Explore diving in Koh Lanta

Koh Lanta offers some of the best diving on the west coast of Thailand. Boasting vibrant reefs, deep drop-offs and alluring caves, Koh Lanta is a hotspot for scuba divers looking for adventure.

Expect to see the usual suspects on the colorful reefs. Gorgonian sea fans sway in the light currents and pinnacles are swarmed with carpets of anemone.

When to dive in Koh Lanta

Koh Lanta enjoys warm waters filled with marine life throughout the year with sea temperatures averaging around 84°F/29°C. February-May is when the seas are at their flattest and dive conditions are calm.

Depending on the season you can expect anything between 15-40m visibility. When visibility is reduced from the plankton in the water, big fish appear. Manta rays and whale sharks visit deeper pinnacles annually. The best time of year to spot them is from February-April. Nature’s calendar doesn’t always follow the rules though so these beauties can be spotted at any time of the year.
