Khao Sok National Park is a vast tropical rainforest reserve in southern Thailand known for its exceptional biodiversity, dramatic limestone karst formations, and the stunning Cheow Lan Lake, offering unique wildlife encounters and outdoor adventures.
Located in Surat Thani Province in southern Thailand, Khao Sok National Park is one of the oldest rainforests in the world, dating back approximately 160 million years. The park encompasses over 700 square kilometers of dense jungle, towering limestone cliffs, deep river valleys, and the striking man-made Cheow Lan Lake, created by the Ratchaprapha Dam. Khao Sok's complex ecosystem supports a wide spectrum of flora and fauna, including rare species such as the Malayan tapir, Asian elephants, gibbons, hornbills, and countless tropical plants and orchids. Its karst landscape is characterized by limestone towers reaching over 900 meters high, caves, and underground rivers. Visitors can explore the park through guided jungle trekking, canoeing on the Sok River, and boat tours on Cheow Lan Lake, where floating raft houses provide unique accommodations. Notable sites include the Batu Caves, Nam Talu Cave, and the viewpoint at Guilin of Thailand, famous for its panoramic views of the lake and limestone pinnacles. Wildlife observation opportunities are excellent, with night safaris and bird-watching being popular activities. Khao Sok appeals to outdoor enthusiasts, nature lovers, and those seeking a remote wilderness experience combined with eco-friendly accommodations and cultural encounters with local communities. Responsible tourism plays a key role in preserving this natural treasure.
