Cambodia's 12 National Parks, Province by Province

A guide to Cambodia's twelve national parks, from Virachey and Veun Sai–Siem Pang in the far northeast to Bokor, Ream and Koh Rong in the south.

Most trips to Cambodia are planned around temples, and understandably so. But the country also protects a long list of mountains, forests, coastlines and islands, spread from the Vietnamese border to the Gulf of Thailand. Here are twelve of them, what each one looks like, and where to find it.

1. Virachey, in the far northeast

Virachey sits across Ratanakiri and Stung Treng, in the corner of the country that borders both Laos and Vietnam. It is one of the largest protected areas in Cambodia and one of the least visited: grass-covered ridges falling away into forested valleys, with mist sitting in the folds well into the morning. Trips here are organised locally and usually run several days.

2. Kirirom, the pine forest near Phnom Penh

Kirirom is in Kampong Speu, close enough to Phnom Penh for a day out. The draw is the pine forest — tall, straight trunks and dirt tracks through the grass, at an altitude where the air is noticeably cooler than the plain below. It is the easiest park on this list to reach without planning.

3. Kep, small and coastal

The park above Kep is the smallest here, a wooded hill rising directly behind the town with a path circling it. From the higher stretches you look out over the bay and across to the islands. Easy to add to a slow weekend on the coast.

4. Phnom Kulen, the sacred mountain

Phnom Kulen is an hour or so from Siem Reap, and the one park most travelers already have on their list. It holds carved stone animals, riverbed carvings and waterfalls among the trees — the elephant pictured here is one of several figures left in the forest. If you are already exploring the area, our guide to the lesser-known temples around Siem Reap covers what else is worth the drive.

5. Preah Monivong, better known as Bokor

On the plateau above Kampot, Bokor is where the old hill station was built, and the abandoned church still stands with the mountains behind it. Cloud moves across the plateau for much of the year, which is most of the appeal — and the reason the view can disappear entirely within minutes.

6. Botum Sakor, forest and river in Koh Kong

Botum Sakor occupies a large peninsula in Koh Kong, on the southwestern coast. Seen from above it is dense canopy cut by a slow river winding towards the sea. Access is limited and mostly by boat or unsealed road.

7. The Central Cardamom Mountains

The Cardamom range runs across southwestern Cambodia, spanning Koh Kong and Pursat, and holds some of the largest continuous rainforest in mainland Southeast Asia. Roads through it are narrow and green on both sides, with the ridgeline showing through the gaps. Community-run ecotourism projects operate at several points along the edges.

8. Ream, on the Sihanoukville coast

Ream covers mangrove, estuary and beach just outside Sihanoukville. The picture here is what most of it looks like from the water: palms, a wooden walkway, fishing boats tied up beside a hut with a rusted roof. Boat trips leave from the villages inside the park.

9. Koh Rong, protected underwater

The waters around Koh Rong are protected as a marine park, which is the part visitors tend to miss while they are on the beach. Below the surface there is coral and reef fish — the parrotfish pictured is a common sight on a snorkelling trip. Conditions vary a lot by season and by site.

10. O'Yadav, in eastern Ratanakiri

O'Yadav lies along the Vietnamese border in Ratanakiri, a mix of forest and open grassland. It is one of the areas where wild cattle are still seen at the forest edge, as in the photograph here. Visits go through local operators in Banlung.

11. Veun Sai–Siem Pang, for birdlife

Veun Sai–Siem Pang protects lowland forest in the northeast and is known above all for its birds — bee-eaters, hornbills, and rarer species that draw birdwatchers specifically. It is also one of the sites associated with conservation work on gibbons.

12. Phnom Aural, the highest point in the country

Phnom Aural rises in central Cambodia and is the highest mountain in the country. The landscape is layered ridges with mist sitting between them at sunrise, as pictured. Climbing it is a guided multi-day walk rather than a day trip.

Before you go

These parks vary enormously in how easy they are to visit. Kirirom, Kep, Phnom Kulen and Bokor can be reached on a normal day trip; Virachey, Botum Sakor, O'Yadav and Phnom Aural generally cannot, and are arranged through operators in the nearest town. Entrance arrangements, ranger stations and road conditions all change from one season to the next, so check locally before setting out rather than relying on anything written in advance — including this page.

The dry season, roughly November to April, is the simpler window for the northeastern and mountain parks. The coast and the islands work year-round, with visibility underwater changing month to month.
