Why Koh Lanta?

Scuba diving around Koh Lanta is relatively easy. Most dive sites are in the 5m - 25m depth range where we have the most sunlight, best colours and widest diversity of marine life on the coral reefs.

The dive sites, marine life and coral reefs are far more extensive, diverse and healthier in the Andaman Sea compared to the Gulf of Thailand. The perfect environment for teaching all PADI courses.
