Khao Sok National Park is a remarkable feature of the geography and culture of Thailand. A landscape of towering limestone karsts and ancient rainforest older than the Amazon. Its centerpiece is Cheow Lan Lake, an emerald reservoir that feels like an alien sea. Contains one of the world's oldest evergreen rainforests. Home to the rare Rafflesia flower, one of the world's largest. Cheow Lan Lake was created in 1982 by the Ratchaprapha Dam. This natural area reflects the scenic diversity of Thailand, from the Mekong basin to the islands of the Andaman Sea. Like many notable places in Thailand, it combines regional character with the legacy of the Chao Phraya, the Mekong and Buddhist tradition. Thus, this place contributes to the diverse profile of Thailand, between the Andaman coast, rice paddies and tropical forests.

Getting there
The national park is situated in Surat Thani province, easily reached by bus or private transfer from popular hubs like Phuket, Krabi, or Surat Thani, acting as main gateways for visitors.
Best season
While accessible year-round, the driest and most pleasant weather occurs between December and April, though visiting just after the rainy season has spectacularly lush landscapes and full waterfalls.
Terrain & paths
The terrain features an intricate network of dense jungle trails, muddy forest floors, and steep viewpoints, alongside the vast expanse of the lake which requires navigation by traditional longtail boat.
What to bring
Essential gear includes lightweight, breathable hiking clothing, a reliable raincoat, waterproof bags for boat trips, strong mosquito repellent, and leech socks if trekking during wetter months.
Parking
Secure parking is generally available at the park headquarters in Khao Sok village and near the Cheow Lan Lake pier, where many tours originate and visitors often leave their rental vehicles.
Safety
Hiking independently on deep jungle trails can result in getting easily lost, so hiring a licensed guide is highly recommended; visitors should also exercise caution when swimming in the deep lake waters.
Time needed
To fully appreciate both the ancient rainforest and the majestic reservoir, visitors typically spend at least two to three days, often spending a night on the lake in floating raft houses.
