In short
Ratanakiri is Cambodia’s far north-east, about 493 km by road from Phnom Penh, with Banlung as its base. Most visitors come for Yeak Laom, a round volcanic crater lake you can swim in, nearby waterfalls and the gateway to Virachey National Park. It needs at least three nights and pairs best with a stop in Kratie or Stung Treng.
Ratanakiri is the far corner of Cambodia, where the country meets Laos and Vietnam. The landscape is red earth, cashew and rubber plantations, forest and rivers, and the population includes several Indigenous peoples, among them the Tampuan, Jarai, Kreung and Brao. Banlung, the provincial capital, is a small, dusty town and the base for everything.
Yeak Laom and the waterfalls
Yeak Laom is a near-perfect circle of clear water in an old volcanic crater, ringed by forest about 5 km from Banlung. Local Tampuan communities have managed the site for years under a lease, with entrance fees going towards village needs; current arrangements may have changed since that lease was due to end in 2021. You swim from wooden platforms, walk the path around the rim and, ideally, arrive early before the day warms up.
Several waterfalls lie within a short drive of town, plunging into forest pools. In the dry season they shrink; in the wet season they are at their most dramatic but the tracks to them can be slippery.
Indigenous communities and Virachey
Ratanakiri is home to many Indigenous villages, and some visits are arranged through community guides. Approach them as a guest, not a sightseer: go with a guide the community has chosen, ask before photographing people, and expect simple conditions.
To the north lies Virachey National Park, one of Cambodia’s largest and least visited protected areas. Treks there are organised through the park office in Banlung with rangers and community guides. It is a serious undertaking, covered honestly on our Virachey page.
Getting there and time needed
From Phnom Penh it is about 493 km by road; buses take roughly 8.5 to 11 hours according to published timetables and traveler reports. Stopping in Kratie (about 244 km from Banlung) makes the trip far more pleasant and adds the Mekong dolphins. Allow at least three nights in Banlung to make the journey worthwhile.
Ratanakiri or Mondulkiri?
Both are hill provinces in the east with Indigenous communities and forest. Mondulkiri is closer and has the stronger organised wildlife days; Ratanakiri has the lake, the waterfalls and a more remote feel. See Mondulkiri or Ratanakiri.

Questions travelers ask
How long does it take to get to Banlung from Phnom Penh?
Published bus times range from about 8.5 to 11 hours for roughly 493 km. A private car is faster but it is still most of a day. Breaking the journey in Kratie is much more comfortable.
Can you swim in Yeak Laom?
Yes. Swimming in the clear crater lake from wooden platforms is the main reason people go. The site charges a small entrance fee; reported amounts vary between sources, so carry some small US dollar notes or riel.
Should I choose Ratanakiri or Mondulkiri?
Mondulkiri is closer to Phnom Penh and stronger for organised wildlife days (elephants and gibbons). Ratanakiri is further, more remote-feeling, and better for lakes and waterfalls and as a gateway to Virachey. With under two weeks in Cambodia, most people pick one. Our comparison sets out the details.
Can I go between Mondulkiri and Ratanakiri directly?
There is a road north from Sen Monorom through Koh Nhek, about 182 km to Banlung, but older traveler and rider reports describe rough sections and wet-season mud, and most split it with a night on the way. Current conditions need checking before planning around it; the long way round via the main highways is more predictable.
