Phnom Thom: Hiking Cambodia’s Quiet Southern Mountain

Why Visit Phnom Thom

Phnom Thom rises from the coastal plain of southern Cambodia, offering hikers a rewarding climb through dense forest to open viewpoints overlooking the Gulf of Thailand and surrounding countryside. The mountain forms part of the broader range that includes Bokor, yet it remains quieter and less developed, making it ideal for travelers seeking a genuine nature experience rather than crowded viewpoints.

What to See and Do

The main activity is the hike itself. Trails wind through secondary jungle where tall dipterocarp trees shade the path and vines drape between trunks. Birdsong is constant, and lucky hikers may spot monkeys or hornbills. Near the summit, vegetation opens to reveal 360-degree panoramas that stretch from the sea to the distant Cardamom Mountains on clear days. Some visitors combine the climb with a picnic at a rocky clearing just below the highest point.

Trails and Difficulty

Two main routes exist: a steeper southern approach starting near small villages and a gentler northern track that follows an old logging road for part of the way. Both reach the summit in three to five hours depending on fitness and stops. The terrain is uneven with roots and rocks, so sturdy shoes are essential. No technical climbing is required, but the final section can be slippery after rain.

Getting There

Phnom Thom lies roughly 20 kilometers inland from Kampot. Most visitors arrange a moto or tuk-tuk driver for the day; the driver waits at the trailhead while the group hikes. Independent travelers can rent a motorbike in Kampot and follow the road toward the mountain, turning onto a dirt track marked by local signs. Four-wheel-drive vehicles are advisable during the wet season when sections become muddy.

Best Time to Visit

The coolest and driest months, from November through February, offer the most comfortable hiking conditions and clearest views. March and April remain dry but grow hotter, while the May-to-October monsoon brings heavy rain that makes trails muddy and leeches more active. Early morning starts are recommended year-round to avoid midday heat and to catch the best light at the summit.

Nearby Attractions

Many travelers pair Phnom Thom with a visit to Kep’s crab market or the colonial ruins on Bokor Mountain. The coastal road between Kampot and Kep provides easy access to both the mountain and seaside destinations, allowing a full day of varied scenery.
