Phnom Aural: Trekking Cambodia’s Highest Mountain in the Cardamom Range
Cambodia's tallest peak offers serious trekkers remote jungle trails, rare wildlife, and sweeping highland views.
Why Phnom Aural Stands Out
At 1,813 meters, Phnom Aural is Cambodia’s highest point and the centerpiece of the southern Cardamom Mountains. The mountain rises steeply from lowland evergreen forest into cooler montane woodland, creating a rare habitat for species such as the Asian elephant, clouded leopard, and several endemic birds. Because the area remains sparsely populated, visitors experience genuine wilderness rather than crowded viewpoints.
Trekking the Summit
Most ascents begin at trailheads near the villages of Kirirom or Phnom Srouch in Kampong Speu Province. The route climbs through bamboo groves and mossy forest, crossing small streams that feed the Prek Teuk Chhou river system. The final ridge walk delivers 360-degree views over the Cardamom plateau and, on clear days, toward the Gulf of Thailand. Multi-day treks with overnight camps are standard; the terrain is steep and unmarked in places, so experienced local guides are essential for navigation and safety.
Flora and Fauna Highlights
Lower slopes hold dipterocarp forest while higher elevations feature rhododendron and pitcher plants. Birders often record great hornbills and the rare chestnut-headed partridge. Mammal sightings are uncommon but possible at dawn or dusk near water sources.
Getting There
From Phnom Penh, travelers drive National Road 4 to Kampong Speu town, then continue on secondary roads toward the mountain’s eastern flanks. Four-wheel-drive vehicles are recommended beyond the main highway, especially after rain. Public transport reaches only the district centers, after which motorcycle taxis or arranged transfers are needed to reach trailheads.
Best Time to Visit
The dry season from November through April offers the most reliable trail conditions and clearest summit views. The wet season brings leeches, slippery clay, and occasional trail washouts, though the forest is lush and waterfalls are at peak flow. Avoid the peak of the southwest monsoon if possible.
Nearby Attractions
Combine a Phnom Aural trek with visits to Kirirom National Park for pine-forest walks and waterfalls, or continue westward into the Central Cardamom Protected Forest for river rafting on the Stung Pursat. The historic town of Kampong Speu itself offers quiet markets and access to nearby pepper plantations.
Visitor tips
- Hire a licensed local guide through Kampong Speu tourism authorities; trails lack signage and mobile coverage is limited.
- Pack lightweight rain gear, sturdy boots with good tread, and plenty of water even in the dry season.
- Register your trek with village authorities at the trailhead to aid rescue efforts if weather turns.
