Caving & Cheow Lan Lake in Khao Sok

Karst towers ring an emerald reservoir cut by long, deep arms. Longtail rides reach raft houses, viewpoints, and trailheads to caves with ornate chambers. Park staff may require guides for flood-prone caves, and rangers close routes after heavy rain. Wear a helmet and headlamp, keep hands off stalactites, and watch footing on slick calcite. Coral Cave and Nam Talu sit on many plans, with swims and squeezes that add spice. Sleep on the lake for sunrise mist and gibbon calls, then paddle back past buttressed trees that rise from the water.
