Phnom Kulen is a sacred mountain in Cambodia, revered for its historical and religious significance. It features ancient temples like Preah Ang Thom with its massive reclining Buddha, waterfalls, and the River of a Thousand Lingas. Accessibility can be challenging due to the road conditions, and a 4x4 vehicle is recommended. While solo visits are possible, a guided tour can enhance the experience with insights into the area's history and culture. There may be some seasonal restrictions during the rainy season (May-October) due to road conditions, so it's best to visit during the dry season (November-April). The approximate cost, including transportation and entrance fees, can range from $30 to $80 USD per person. A typical visit duration is around 4-6 hours, allowing sufficient time to explore the key attractions.
