Koh Lanta Marine Life with Dive & Relax

After returning from a trip, our dive staff love to spend time with our guests, logging the dives and sharing our knowledge of the wonderful marine life at the dive sites around Koh Lanta.

Underwater Photographers love Koh Lanta Diving

Koh Lanta diving is easy and relaxed. With relatively shallow reefs, sheltered lagoons and gentle drop-offs, most of our reef life is in the 5m to 20m depth range.

Divers love the great visibility, dramatic underwater topography, and huge diversity of corals, fish, crustaceans, slugs, snails, sponges and thousands of other species found around Koh Lanta.

Shallower diving means you get to spend more time underwater, where the colours are more vibrant, and the marine life is most abundant. Koh Lanta diving is a fantastic choice for underwater photographers.
