Illustrative journey ideas — not bookable packages. No prices, dates or accommodation are implied.
Most travellers see two things in Cambodia: Angkor and the southern coast. The north-east is different. Here the Mekong is at its widest and calmest, its deep pools home to the river's last Irrawaddy dolphins, and further east the plains rise into the green hills of Mondulkiri, home of the Bunong people, where gibbons can still be heard in the forest. The roads are long and the stays simpler, but no two days are alike.
The journey begins in Phnom Penh and ends in Siem Reap, but takes the long way round. In Kratie, a boat among the dolphins and a bicycle across an island of pomelo orchards; in Mondulkiri, a day with elephants that live freely in the forest, and an early walk with Bunong guides looking for monkeys in the canopy. On the way to Angkor, Koh Ker, briefly the capital of the Khmer empire, its seven-tiered pyramid rising out of the forest. It's a journey for experienced, curious travellers who care more for nature and history than for comfort.

01Days 1–3 · Phnom Penh
A capital of rivers
Two nights in Phnom Penh, where the Mekong meets the Tonlé Sap, a good place to rest after the flight and find your feet. In the morning, the Royal Palace and the Silver Pagoda, the National Museum, whose Khmer sculpture you'll recognise later at Koh Ker and Angkor, and the Central Market under its yellow Art Deco dome. In the afternoon, a calm conversation with a guide about the country's 20th-century history and, if you feel ready, the Tuol Sleng Genocide Museum, which we visit quietly and with respect. In the evening, sunset on a boat on the river and dinner on the waterfront. On day three it's about four and a half hours north along the Mekong; on the way, in Kampong Cham province, the river is already wide, calm and unbuilt along its banks.
02Days 3–5 · Kratie
Dolphins in a quiet pool
Kratie is a small town of French-era houses and a riverfront where the sunsets over the Mekong are among the finest in the country. Two nights here. Early in the morning or late in the afternoon, about 15 km north to the Kampi pool, home to Irrawaddy dolphins: round-headed and without a distinct beak, they surface quietly to breathe and slip back into the brown water. Community boatmen approach them very carefully, often with the engine off, so waiting and silence are an essential part of the experience. The dolphins are usually seen, but no one can promise it. The next day, a ferry to Koh Trong, the island facing the town: by bicycle past pomelo orchards, wooden houses and monasteries, with lunch at a village home.
03Days 5–8 · Mondulkiri
Elephants, gibbons and the Bunong hills
About three and a half hours east, the plain rises into rolling green hills with stands of pine: Mondulkiri, a sparsely settled upland of cool evenings and simple lodges. Three nights near Sen Monorom. One day with a project where elephants retired from logging and tourism live in the forest: they are not ridden or bathed, and visitors walk with guides to watch them from a distance and help care for the forest. The next morning, before dawn, the Keo Seima forests, where Bunong community guides lead walks in search of black-shanked doucs and gibbons, which you often hear long before you see them. We visit Bunong villages only with local guides and on their terms.
04Days 8–9 · Koh Ker
A pyramid deep in the forest
The longest day of the journey: some seven or eight hours west via Kratie and Stung Treng province, with stops along the way. A night in a simple guesthouse near Koh Ker. In the first half of the 10th century this was briefly the capital of the Khmer empire, and dozens of temples rose here in a few decades. The greatest is Prasat Thom, a seven-tiered pyramid rising above the forest canopy; the towers of some other temples are already wrapped in tree roots. In the early morning there is almost no one here but birds and guardians. The area was cleared of landmines over many years, so we always keep to marked paths. On the way to Siem Reap, Beng Mealea, a vast, collapsing temple whose courtyards you cross on wooden walkways between mossy stones.
05Days 9–11 · Siem Reap & Angkor
Angkor in the quiet hours
About two and a half hours to Siem Reap and two nights to finish. After Koh Ker and Beng Mealea, Angkor looks different: you can see how the same building tradition reached its height here. We plan the temples so you see the great ones at quieter times: Ta Prohm early in the morning, the Bayon in the late afternoon and Angkor Wat once the crowds have gone. Free time for a bicycle among the smaller temples, dinner in the old town or a performance at the circus where young Cambodian artists perform. On the last day, a flight out of Siem Reap via one of the region's hubs.
Experience highlights
- 01
Irrawaddy dolphins
A quiet wait in a boat at the Kampi pool until a round head breaks the surface.
- 02
A day with elephants
Elephants that live in the forest rather than work: no riding, with respect and distance.
- 03
Morning in the Keo Seima forest
Gibbon song and Bunong guides who know the forest better than anyone.
- 04
The Koh Ker pyramid
The seven-tiered Prasat Thom and temples that are almost empty in the morning.
First, we listen. Then, we explore what's possible.
Make it your own
At a slower pace
The longest day can be split with a night in Kratie or Stung Treng, and a fourth night added in Mondulkiri.
For nature lovers
More time in the Keo Seima forests and, in the dry season, birdwatching on the plains of Preah Vihear province with local guides.
With the seasons
In the dry season the roads are better and the dolphins gather in the deep pools; in the rainy season Mondulkiri is greenest but the roads are slower.
With the coast or Laos
After Angkor, a few days on the coast at Kampot and Kep, or from the north-east into southern Laos and the Four Thousand Islands.
Practical considerations
- The best time is the dry season, roughly November to April, with December and January the coolest. In the rainy season (roughly May to October) some roads, especially to Mondulkiri and Koh Ker, become slow, so we plan with time in hand.
- The journey is planned with a driver and guide: distances are long, and stays beyond Phnom Penh and Siem Reap are usually simple but clean.
- We watch the dolphins only from community boats that keep their distance and their quiet, and visit elephants only at a project where they are not ridden. We check the rules before you travel.
- Some remote areas were once mined; we always keep to marked paths and travel with a local guide.
General guidance only. Seasons, weather and wildlife are never guaranteed, and travel requirements are always worth checking before you go.
