Main highlights: Banteay Chhmar Temple, northwestern countryside, Anlong Veng historical sites and the Dangrek landscape
Overnight: Sraem

The adventure begins early in Siem Reap with a detailed safety briefing, motorcycle familiarisation and luggage inspection. A BMW GS 1250cc is a powerful long-distance machine, but Cambodia rewards smoothness rather than speed. Riders will be reminded to maintain generous following distances, watch for livestock and village traffic, and avoid sudden braking on dusty road shoulders.

Leaving Siem Reap behind, we ride west through broad rice plains and farming communities before turning north towards Banteay Chhmar. Hidden among rural villages, this enormous temple complex was built during the reign of Jayavarman VII. Its weathered galleries, carved faces and partially collapsed stone corridors create an atmosphere that feels markedly different from the more frequently visited monuments around Angkor. Banteay Chhmar is also associated with a community-based tourism initiative that connects temple visits with local livelihoods and village experiences. 

After time to explore the temple respectfully, we continue towards Samraong, the provincial capital of Oddar Meanchey. The riding becomes quieter here. Long, straight roads cross sugar-palm country, while occasional laterite lanes provide the first taste of Cambodia’s red-earth terrain.

The afternoon brings us to Anlong Veng, a place requiring thoughtful interpretation. Once connected to the final strongholds of the Khmer Rouge, the district contains locations associated with Ta Mok and the last chapter of Cambodia’s civil conflict. These sites are not presented as attractions in a celebratory sense. Instead, they offer an opportunity to reflect on the suffering, political isolation and unfinished memories that continue to shape modern Cambodian society.

From Anlong Veng, the route turns east beneath the Dangrek Mountains. The final kilometres to Sraem are usually a test of concentration after a long day in the saddle. We arrive before dark, refuel the motorcycles, inspect tyres and controls, and settle into our hotel near the gateway to Preah Vihear.

Comparable BMW motorcycle itineraries calculate this stage at approximately 373 kilometres, making it one of the tour’s longest opening days. 

Estimated distance: 330–370 kilometres
Estimated riding time: 7–8 hours, excluding the temple visit
Road character: Sealed roads, steep mountain access, open provincial highways and possible gravel or construction sections
Riding level: Challenging
Main highlights: Preah Vihear Temple, Dangrek escarpment, remote northern Cambodia and the Mekong–Sekong river town of Stung Treng
Overnight: Stung Treng

An early departure is essential today. From Sraem, we ride towards the Dangrek Mountains, which rise abruptly above the plains and form Cambodia’s natural northern frontier. The morning air is cooler, traffic is limited and the silhouette of the escarpment grows steadily larger as we approach the mountain.

When officially open and considered safe, the centrepiece of the day is Preah Vihear Temple. Dedicated to the Hindu god Shiva, the sanctuary stretches along an approximately 800-metre axis of stairways, ceremonial approaches and successive temple enclosures. Construction developed over several centuries, with much of the surviving complex dating from the first half of the 11th century. Its dramatic position above the Cambodian plain is inseparable from its architectural meaning: each level feels like another stage in a ritual ascent from the human world towards the sacred mountain. 

The visit requires walking, so riding boots may be changed for lighter footwear where practical. Photography must follow local instructions, particularly around military or restricted areas. Riders must never leave recognised roads or marked paths because landmines and unexploded ordnance remain a risk in Cambodian border areas. 

After descending from the mountain, we turn east and begin the long trans-Cambodian stage towards Stung Treng. This is classic big-bike touring country: open horizons, isolated villages, stretches of forest and long sections where the boxer engine settles into an effortless rhythm. Fuel, hydration and rest stops must be carefully managed because facilities become less frequent away from the larger settlements.

The landscape slowly changes as we approach the Mekong basin. Stung Treng stands near the meeting of the Mekong and Sekong river systems and has long functioned as a trading gateway between Cambodia and Laos. The province is known for wetlands, river islands, kayaking and nature-based tourism. 

We finish beside the river, where fishing boats, food stalls and the fading evening light create a peaceful contrast to the scale of the day’s ride. After checking the bikes, riders can enjoy dinner at a local riverside restaurant.

Operational replacement while Preah Vihear remains closed: Tbeng Meanchey – remote village roads – Stung Treng, avoiding the Thai-border exclusion zone.

Estimated distance: 180–220 kilometres
Estimated riding time: 4–5 hours, plus local sightseeing
Road character: Mostly sealed highway with optional red-earth plantation roads
Riding level: Easy to moderate
Main highlights: Sekong River, northeastern countryside, Yeak Laom volcanic lake, indigenous culture and optional Kachanh Waterfall
Overnight: Banlung

After two demanding stages, today offers a shorter and more relaxed ride. We leave Stung Treng across the Sekong River and follow the eastern road towards Ratanakiri, a province distinguished by red volcanic soil, forests, rubber plantations and the cultural diversity of its indigenous highland communities.

The main road allows the BMW GS to stretch its legs, but the journey is not about maintaining high speed. Farm vehicles, motorcycles joining unexpectedly from village tracks, wandering cattle and patches of loose material can appear without warning. We keep the group compact and stop regularly for photographs, fresh fruit and local coffee.

As we ride east, the soil becomes increasingly red, staining roadside tracks and the lower parts of the motorcycles. Small wooden homes stand among cashew, rubber and cassava fields. These cultivated landscapes also reveal how rapidly northeastern Cambodia is changing. Forests, commercial agriculture and indigenous land-use traditions now exist beside one another, sometimes uneasily.

Arriving in Banlung around midday, we have lunch before visiting Yeak Laom Lake, approximately five kilometres from town. The nearly circular body of clear water lies inside a volcanic crater and is surrounded by forest. A path loops around the lake, and a small cultural centre traditionally displays handicrafts made by local indigenous communities. The setting is quiet, shaded and ideal for recovering after the previous day’s long-distance ride. 

Guests should approach local customs with sensitivity. Photographs of community members should never be taken without permission, and cultural traditions should not be reduced to staged entertainment.

Depending on arrival time and seasonal water levels, we may continue to Kachanh Waterfall, located around six kilometres from Banlung. The waterfall drops approximately 12 metres into a forested setting reached by a wooden stairway. Rubber plantations and red-earth lanes surrounding the area can provide an enjoyable, low-pressure ADV riding section before returning to town. 

The evening is free in Banlung. Riders can explore the local market, enjoy a cold drink and prepare for tomorrow’s highly scenic crossing into Mondulkiri.

Estimated distance: 230–280 kilometres
Estimated riding time: 5–6 hours, excluding sightseeing
Road character: Flowing sealed mountain road, rolling hills, forest sections and occasional gravel shoulders or roadworks
Riding level: Moderate
Main highlights: Route 76, northeastern highlands, Bousra Waterfall and Mondulkiri’s “Ocean of Trees”
Overnight: Sen Monorom

Today delivers one of the finest pure riding experiences of the expedition. Leaving Banlung, we turn south towards Mondulkiri on Route 76, crossing a sparsely populated region of forests, plantations and rolling uplands.

Once known among overland riders as a difficult and sometimes punishing connection, the main Banlung–Sen Monorom route has since been substantially sealed. Recent rider reports describe a paved journey of roughly 198 kilometres between the two provincial capitals, although roadworks, damaged edges and seasonal debris may still change conditions without notice. 

This is where the BMW GS feels at home. Broad handlebars, long-travel suspension and strong mid-range power make the machine ideally suited to flowing highland roads. Yet the weight of a fully fuelled 1250cc motorcycle demands respect. Riders should enter bends conservatively, avoid cutting corners and remain alert for sand, gravel and slow-moving agricultural vehicles.

We pause near Koh Nhek for refreshments and a simple local lunch before continuing through cooler, greener hills. Mondulkiri is one of Cambodia’s least densely developed regions and is widely associated with eco-tourism, forest landscapes and waterfalls. It is also home to Bunong communities whose relationship with the land, forests and elephants extends far beyond the tourism experiences commonly presented to visitors.

Before reaching Sen Monorom, we take a scenic detour to Bousra Waterfall, approximately 43 kilometres from the provincial capital. Bousra is one of Mondulkiri’s best-known natural sites, where water descends through a forested valley in powerful stages. Its appearance varies considerably between the dry and wet seasons, and pathways may become slippery after rain. 

The final ride into Sen Monorom climbs through pine-like landscapes and open hills. Near town, we stop at the Ocean of Trees viewpoint, where layers of green ridges stretch towards the horizon. The light is often at its finest in the late afternoon, when the forest canopy appears to roll like waves beneath the sky. 

We arrive at the hotel with time for a motorcycle inspection, followed by dinner in the cool highland atmosphere of Sen Monorom.

Estimated distance: 300–350 kilometres
Estimated riding time: 7–8 hours, excluding the dolphin excursion
Road character: Mountain descent followed by fast sealed highways and increasingly busy provincial roads
Riding level: Moderate to challenging due to distance
Main highlights: Mondulkiri highlands, Kratié riverside, Kampi dolphin habitat, Chhlong and the Mekong River corridor
Overnight: Kampong Cham

We leave Sen Monorom early and descend from the highlands towards Snuol. The morning section carries us through forest edges, plantations and long sweeping bends before the road begins to flatten. Temperatures rise noticeably as we leave the plateau, so hydration stops become increasingly important.

At Snuol, we join National Road 7 and continue towards Kratié. The surrounding countryside is dominated by farms, cashew plantations and small settlements where roadside stalls sell fruit, drinks and simple Khmer snacks. This section is generally faster, but traffic becomes more unpredictable. Trucks, tractors and local motorcycles may use the shoulder or change direction without warning, making defensive riding essential.

Arriving near Kratié, we continue north to Kampi, approximately 15–16 kilometres from town and regarded as the province’s principal location for observing freshwater Irrawaddy dolphins. A short boat trip may be arranged when river, weather and timing conditions permit. Boats should maintain a respectful distance, minimise noise and never chase the animals. 

The dolphins are not simply a tourism highlight; they are part of a fragile Mekong ecosystem shared by riverside communities. The experience is often quiet and understated—a curved back breaking the surface, a breath of air, then still water again.

After lunch in Kratié, we turn south and follow the Mekong corridor. The town itself retains a relaxed riverside character, with old shop houses and shaded streets facing the river. Farther downstream, we pass Chhlong, another small town known for its riverfront atmosphere and remnants of colonial-era architecture.

The final stage to Kampong Cham is a sustained ADV touring run. The road is mostly paved, but heat, traffic and accumulated fatigue make concentration more important than speed. We reach Kampong Cham in the late afternoon and cross or view the broad Mekong beside the city.

Kampong Cham’s surrounding province is known for fertile agricultural land, rubber, tobacco and tropical crops, while the city retains traces of French-era architecture alongside modern Cambodian life. 

After checking in, riders can walk along the riverfront or enjoy a relaxed dinner overlooking the Mekong.

Estimated distance: 300–330 kilometres
Estimated riding time: 6–7 hours, excluding visits
Road character: Primarily sealed national roads with city traffic, village sections and possible construction diversions
Riding level: Moderate
Main highlights: Wat Hanchey, Mekong landscapes, Skun, pottery traditions of Kampong Chhnang and Tonle Sap countryside
Overnight: Pursat

The day begins with a short ride outside Kampong Cham to Phnom Hanchey, a hilltop religious site overlooking the Mekong countryside. The elevated setting provides a calm start to the morning, with views across fields, river channels and rural settlements. Kampong Cham is home to several historical and religious sites, including Hanchey, Nokor Bachey and Phnom Pros–Phnom Srei. 

Returning to the main route, we cross the Mekong region and ride towards Skun. The town is widely known among travellers for its roadside market, where fried tarantulas and other local snacks are sometimes sold. The stop is presented as a window into regional food culture rather than a spectacle. Guests are free to observe, taste or simply enjoy a coffee before continuing.

The road west becomes busier as we move through central Cambodia. This is not a technical off-road day, but it demands strong road awareness. Large trucks, buses, roadside markets and motorcycles carrying agricultural produce all share the same corridor. The GS’s commanding riding position is useful, yet riders must avoid becoming overconfident on apparently straightforward asphalt.

We bypass the most congested parts of Phnom Penh and continue towards Kampong Chhnang, whose name can be translated as the “Port of Pottery.” The province is known for traditional red-clay ceramics, floating communities and its close connection with Tonle Sap Lake. At villages such as Ondong Rossey, pottery has traditionally been formed by hand, using foot-powered wheels or wooden tools before being fired. 

Time permitting, we stop at a roadside workshop to observe the craft and purchase small locally made pieces that can be safely carried in the support vehicle.

The final kilometres follow National Road 5 towards Pursat. Rice fields, sugar palms and canals accompany us into a quieter provincial town known for marble carving and access to the floating community of Kampong Luang. 

After a long but varied day, we check in, service the motorcycles and enjoy our final evening on the road.

Estimated distance: 280–310 kilometres
Estimated riding time: 6–7 hours, excluding visits
Road character: Mostly paved highway with rural detours and moderate traffic
Riding level: Moderate
Main highlights: Battambang heritage quarter, Bamboo Train or countryside ride, northwest rice plains and return to Siem Reap
Tour ends: Siem Reap

Our final morning begins on National Road 5, riding north from Pursat towards Battambang. The stage is comparatively straightforward, allowing the group to enjoy the rhythm of the open road while remaining alert to trucks, local buses and motorcycles entering from village lanes.

Battambang appears slowly through a landscape of canals, rice fields and traditional houses. Cambodia’s second great historic city is appreciated for its old shop houses, relaxed riverfront and surrounding agricultural countryside. The province also contains ancient temples including Wat Ek, Prasat Banan and Baset Temple. 

After a coffee near the Sangker River, we explore part of the old quarter on foot. Faded façades, balconies and family-run businesses reveal the many layers of Battambang’s history. The city is less monumental than Siem Reap, but that is part of its appeal—it feels inhabited rather than staged.

Depending on the group’s pace and arrival time, riders may choose one short countryside experience. The most accessible option is the Bamboo Train, where a simple rail platform travels through fields outside the city. Alternatively, the group can take a scenic motorcycle loop through farming villages, stopping to observe rice-paper making, fruit cultivation or local food production. The official tourism authority lists the Bamboo Train among Battambang’s characteristic countryside experiences. 

Following lunch, we begin the final ride towards Siem Reap. The journey passes through Sisophon before joining National Road 6. These final hours often feel reflective. Over seven days, the landscape has changed from ancient temple country to remote highlands, from the Mekong River to Tonle Sap’s western plains.

We approach Siem Reap in the late afternoon, regroup outside the city and ride together to the motorcycle base. After refuelling, the bikes are inspected and returned. The journey concludes with a final briefing and a well-earned celebration.

The loop ends where it began, but the Cambodia now carried in memory is far larger than Angkor: a kingdom of rivers, red roads, quiet villages, difficult histories and extraordinary human warmth.

What riding experience is required?

Participants should be confident riding motorcycles above 1,000cc and able to manage a heavy ADV bike at low speed. Experience with gravel, broken asphalt, steep access roads, loose surfaces and long riding days is strongly recommended. This is not an appropriate tour for beginners.

Which motorcycles are suitable?

The preferred motorcycle is a BMW R 1250 GS or BMW R 1200 GS, with equivalent models considered subject to availability. Riders should be familiar with the motorcycle’s weight, electronic riding modes, braking system and luggage arrangement before departure.

Is the route mainly off-road?

No. It is an adventure-touring route rather than a hard-enduro expedition. Most of the journey uses sealed roads, but riders may encounter red laterite, gravel, potholes, damaged shoulders, roadworks, sand and wet-season mud.

Is Preah Vihear Temple currently accessible?

As of 4 August 2026, the UK FCDO reports that Preah Vihear Temple is closed, and official travel advice discourages travel close to the Cambodian–Thai border. The original route must not operate until access, security and insurance coverage have been formally reconfirmed. 

What motorcycle licence is required?

Cambodia’s licensing arrangements for foreign riders require careful verification, especially for motorcycles above 125cc. Cambodia’s Ministry of Public Works and Transport provides a Type A motorcycle licence category for foreigners, while the Australian Embassy notes that international driving permits have not always been accepted. Guests should therefore submit their home motorcycle licence before booking so the operator can confirm current requirements with Cambodian authorities and insurers. 

Is travel insurance compulsory?

Yes. Insurance must specifically cover large-capacity motorcycle riding, medical evacuation and the full itinerary. Standard travel insurance often excludes motorcycles above a certain engine capacity or may become invalid when travelling against government advice.

Is a support vehicle recommended?

Yes. A support vehicle is strongly recommended for groups using BMW GS motorcycles. It can carry luggage, drinking water, spare tyres, tools, medical supplies and a disabled motorcycle if recovery is required.

What is the best time of year?

Cambodia’s dry season generally runs from November to April, with December and January usually offering cooler conditions. For big-bike touring, November to February is normally the most comfortable period, subject to security, road and accommodation availability. 

Can the tour operate during the rainy season?

It may be possible, but daily distances and off-pavement sections must be reconsidered. Cambodia’s rainy season generally runs from May to October, and heavy rain can create flooding, slippery laterite and sudden changes around waterfalls and rural roads. 

Can a pillion passenger join?

A highly experienced rider may carry a pillion, but the long distances, heat and occasional rough sections can be tiring. A support vehicle should be available so the passenger can transfer to the vehicle whenever necessary.

What accommodation standard is expected?

Accommodation is normally comfortable provincial hotel or resort standard with private bathroom, air-conditioning where available and secure motorcycle parking. Standards in remote towns may be simpler than in Siem Reap or Phnom Penh.

Are vegetarian and special meals available?

Vegetarian meals can generally be arranged with advance notice. Vegan, gluten-free or allergy-sensitive requirements require more careful preparation in remote provinces, where ingredient choices may be limited.

Is fuel easily available?

Fuel is available in provincial towns and along major highways, but remote sections require planned refuelling. The guide should identify reliable stations daily, and emergency fuel may be carried by the support vehicle where legally and safely permitted.

What riding equipment should guests bring?

A full-face or adventure helmet, armoured jacket and trousers, riding boots, gloves, rain layer, hydration system, sunglasses and sun protection are essential. Lightweight clothing and sandals should be packed for evenings and temple visits.

Are there landmine risks?

Yes, particularly near former conflict zones and border areas. Riders must never leave recognised roads, marked tracks or authorised temple paths. Metal objects should not be picked up, and all instructions from local authorities must be followed. 

How physically demanding is the tour?

Riders should be able to spend six to eight hours on the motorcycle, cope with heat and maintain concentration over consecutive long-distance days. Good cardiovascular fitness, hydration discipline and adequate sleep are important.
