Cambodia's temples get most of the attention, but the country's natural side is just as compelling once you know where to look — dense rainforest, misty mountains, coastal mangroves and waterfalls all feature across its network of protected areas. National parks offer a genuine way to see a different Cambodia, away from the Angkor crowds, through trekking, birdwatching and wildlife encounters that the temple circuit simply doesn't offer.

Cambodia's protected areas each specialise in something different, so the right pick really depends on whether jungle, mountains, waterfalls or coastline is the priority. These parks slot naturally into Cambodia tour packages from the UAE, adding a genuine nature-and-adventure dimension alongside the country's cultural highlights.

Virachey National Park

Virachey is Cambodia's wildest and most remote park, tucked into the north-eastern provinces of Ratanakiri and Stung Treng near the borders with Laos and Vietnam. At roughly 3,325 square kilometres, it's a vast stretch of forest, mountains and grassland, and one of the country's most biodiverse protected areas. Cambodia's tourism authorities promote it specifically for guided multi-day treks and community-based ecotourism, run in partnership with local villages.

Gibbons, langurs, hornbills and even the occasional bear are all present in the park, though sightings of rarer wildlife are never guaranteed. For genuinely adventurous travellers, Virachey is about as close as Cambodia gets to true wilderness.

Preah Monivong Bokor National Park

Set on Bokor Mountain in Kampot Province, Preah Monivong Bokor National Park combines rainforest, waterfalls and a scattering of historic sites, including crumbling French colonial-era buildings from its time as a hill retreat. The higher elevation brings cooler air and some of the best panoramic views in the country, and the Popokvil Waterfall is a highlight for anyone exploring further into the park.

The park's wildlife-rich rainforest makes it appealing for nature lovers, and its relatively good road access means it's a realistic option even for visitors who don't want a demanding trek to get to the views.

Ream (Preah Sihanouk Ream) National Park

For coastal ecosystems, head to Ream National Park — officially Preah Sihanouk Ream National Park — just outside Sihanoukville. The park combines lowland forest, mangroves, waterways, beaches and islands, making it well suited to boat trips, nature walks, birdwatching and generally easy-going coastal exploring.

It's a strong choice for a relaxed seaside getaway with a bit of nature built in, and a boat trip through the park gives a genuine sense of how forest, river, mangrove and coastline connect along this stretch of Cambodia.

Kirirom National Park

Kirirom, in the Cardamom Mountains of Kampong Speu Province, is Cambodia's oldest national park — officially designated in 1993, though the area was already a hill retreat decades before that. Around 120 kilometres (roughly two to two and a half hours) from Phnom Penh, it's known for its pine forests, waterfalls, cool mountain air and reliably good birdwatching, even if larger wildlife is scarcer here than in some of the country's more remote parks.

It's an easy, low-key destination for short nature walks, photography, or simply escaping the heat of the lowlands, and the waterfalls are at their best during and just after the rainy season.

Phnom Kulen National Park

In Siem Reap Province, Phnom Kulen combines natural beauty with real cultural and historical weight — the mountain is considered sacred in Khmer tradition and holds ancient carvings, a reclining Buddha, and archaeological remains alongside its forests, waterfalls, streams and caves. It fits naturally into an Angkor-focused itinerary, adding a day of nature and history without straying far from Siem Reap.

Hikers, swimmers, sightseers and nature lovers all find something here, which makes Phnom Kulen a particularly good fit for travellers who want to pair Cambodia's cultural heritage with time outdoors.

Botum Sakor National Park

Botum Sakor, in the country's southwest, is one of Cambodia's more significant protected areas, covering large stretches of lowland forest, wetland and coastal habitat that support a genuinely diverse range of wildlife. Its remoteness makes it better suited to travellers after an adventure- and nature-focused trip rather than conventional sightseeing, and guided activities are the safest and most informative way to explore its wilder corners.

Choosing the Right National Park

The best pick comes down to what kind of experience you're after: Virachey for serious trekking and genuine wilderness, Bokor for mountain scenery and waterfalls, Ream for coastal and mangrove exploring, Kirirom for peaceful forest walks and birdwatching, and Phnom Kulen for blending nature with culture. Travel time, weather, accessibility, and the specific activities on offer are all worth weighing before deciding. The wetter months bring lush scenery and fuller waterfalls, while the drier season is generally better suited to hiking and other outdoor activities.

Conclusion

Cambodia's national parks offer far more than good views — they're a genuine window into the country's rainforests, mountains, waterfalls, mangroves, coastline and wildlife, and a quieter, slower side of Cambodia that the temple circuit doesn't show. There's a fitting park here whether the goal is a serious trek or a gentle nature walk, and building one into a Cambodia itinerary adds a dimension that pairs naturally with the cultural highlights — from Virachey's untouched wilderness to Bokor's mountain views to Ream's coastal calm.
