Phnom Samkos stands as the second-highest peak in Cambodia, reaching an altitude of 1,717 meters within the western Cardamom Mountains. It is the focal point of the Phnom Samkos Wildlife Sanctuary, which covers approximately 3,337 square kilometers of rugged, isolated terrain. The area is renowned for its high levels of endemism, hosting species of frogs, birds, and plants found nowhere else on Earth due to its unique microclimates and geographic isolation. The sanctuary's vegetation transitions from dense lowland rainforests to mossy cloud forests at higher elevations, providing critical habitat for endangered mammals like the clouded leopard and sun bear. Historically protected by its remoteness and the remnants of conflict, the area is now a primary focus for international conservation efforts to prevent habitat loss from logging and agriculture. The mountain also serves as a vital water catchment area, feeding several rivers that sustain local communities and downstream ecosystems.

📋 Practical info
Getting there
This incredibly remote mountain area is exceptionally difficult to reach, generally demanding a highly capable four-wheel-drive vehicle negotiating terrible dirt roads originating from Pursat.
Best season
Attempting an expedition here is strictly advised only during the absolute driest months from January to March, as the monsoon rains render the approach trails completely unusable.
Terrain & paths
The landscape represents completely untamed, aggressively rugged mountainous jungle terrain, featuring virtually zero established paths, dense suffocating vegetation, and deep treacherous ravines.
What to bring
Independent survival is impossible without top-tier wilderness expedition gear, massive water capacities, machetes for clearing brush, GPS locators, and robust hammock sleeping systems.
Parking
Expedition vehicles are ultimately parked securely at the last functional outpost or ranger station situated on the sanctuary's periphery, long before any real hiking actively begins.
Safety
This environment harbors extreme dangers including unexploded ordnance, aggressive wildlife, and utter isolation, making the mandated employment of specialist local guides an absolute imperative.
Time needed
Due to the grueling pace necessitated by bushwhacking through trackless forest, achieving the summit typically commands a serious commitment of at least five exhausting, consecutive days.
