A beautiful place a little hidden but that everybody knows and that attracts all tourists tour of local agencies. To really enjoy the Emerald Cave and have the cave for you alone, the best option is to stay in one of the hotels in Koh Mook and go in early morning before the arrival of groups from Koh Lanta, Trang...
The cave is inaccessible at high tide!. The best moment to go to avoid tour groups is to go the morning or late afternoon. Take a mask and snorkel and a waterproof flashlight or frontal lamp to light you in the tunnel.
