Tham Le Khao Kob

ถ้ำเลเขากอบ

A thrilling 4 km boat ride through an underground river cave, where you must lie flat in the boat under low ceilings, with unusual stalactite formations.

Tham Le Khao Kob is located in Huai Yot district in northern Trang and is known as the "Sea Cave". Visitors ride small boats rowed by local boatmen along an underground river through the mountain for about 4 km. Along the way, the stalactites and stalagmites take many shapes, and there are several spots where the ceiling is so low that you must lie flat in the boat to pass, which is quite thrilling. The whole trip takes about an hour, and the fare is per boat (roughly several hundred baht). Wear clothes that can get wet and bring a headlamp. It is about 25 km from Trang city, so you'll need a car or a chartered vehicle.
