Ancient Khmer ruins crown the dramatic cliffs of Khao Phra Viharn National Park, where Thailand meets Cambodia in a spectacular display of both cultural heritage and natural beauty. This UNESCO World Heritage site protects not only the magnificent Prasat Preah Vihear temple complex but also pristine tropical forests, rare wildlife, and some of the most impressive panoramic views in Southeast Asia.
Hiking trails wind through dense deciduous forests where the calls of hornbills and gibbons echo through the canopy. Wildlife enthusiasts can spot Asian elephants, leopards, and over 200 bird species along the park’s well-maintained paths. The main trail leads to the temple ruins perched 525 meters above sea level, offering sweeping vistas across the Cambodian plains. Early morning walks reveal dewdrops on spider webs, the fresh scent of rain-washed leaves, and the gradual awakening of the forest as sunlight filters through the trees. Photography opportunities abound, from close-up shots of intricate stone carvings to wide landscape views that stretch to the horizon.
Peace and solitude define the experience here, far from Thailand’s busier tourist destinations. The combination of spiritual significance and natural tranquility creates a contemplative atmosphere where time seems to slow down. Standing atop the cliff face, with ancient stones beneath your feet and endless sky above, you’ll feel connected to both history and nature in ways that few places can provide.
Visit during cool season (November-February) for the most comfortable hiking conditions and clearest views. The park is accessible by car from Ubon Ratchathani city, about 2 hours drive to the entrance at Baan Phumisral. Bring sturdy walking shoes, sun protection, and plenty of water. Entry fees are 400 baht for foreign adults and 200 baht for children (significantly less for Thai nationals). Camping facilities are available for those wanting to experience the forest at dawn and dusk when wildlife is most active.
