Diving in Koh Lanta

Quick facts

Diving here is by boat only, either speed boat or slow boat. There’s a range of sites accessible from Koh Lanta to suit all levels. There are wall dives, pinnacle dives, wrecks and lagoons in which you can blow bubbles. Some sites can experience current, particularly the deeper open ocean sites, and are more suited to more advanced or experienced divers.

The close by jewel on Koh Lanta’s diving crown is Koh Haa. Calm, pristine and with great visibility this is likely to delight divers of all levels. Expect an hour cruise on a slow boat here. The sites closer to Koh Phi Phi are also readily accessed from Koh Lanta, which means you can still enjoy these even though your preferred holiday base is Koh Lanta. Speedboats will deliver you here in around 45 minutes.

Trips also leave from Koh Lanta to the King Cruiser Wreck, Anemone Reef and Shark Point. These sites are closer to both Koh Phi Phi and Phuket, but if you’re not planning to visit either place, then you do have this option. Koh Lanta also offers the closest access to Hin Daeng and Hin Muang, respectively Red Rock and Purple Rock. These rich, deep open ocean seamounts attract manta rays and some whale sharks too.
