Ko Rok

Ko Rok Dive Site – Ko Lanta, Thailand. Suitable for scuba divers and snorkellers of all levels.


Ko Rok at a GlanceThe two sister-islands of Ko Rok offer beautiful diving with fabulous beaches and are suitable for divers and snorkellers of all levels.

Located approximately 25km south of Ko Haa and visible on the horizon from Kantiang Bay, Ko Rok offers relatively shallow diving with abundant marine life and thriving corals in the shallower areas. The corals are among the best in the area at these dive sites.

We make trips to Ko Rok once or twice per week during high season on board the luxurious MV Ja Ru Pat.

Featherstar at Ko Rok, Ko Lanta, ThailandKo Rok is best known as the top snorkelling site around Ko Lanta, and very few dive centres offer scuba diving trips to these great sites. Our location in the South of Ko Lanta gives us great access to these little known dive sites. The islands are quite large and we are still discovering new and exciting diving opportunities at these sites.

The shallow channel between Ko Rok’s twin islands reaches a maximum depth of 15 m, which makes Ko Rok a great destination for students, beginner divers and snorkellers.

Beach at Ko Rok Dive Site Ko Lanta, ThailandThe uninhabited islands of Ko Rok (Ko Rok Nai – Inner Rock, and Ko Rok Nok – Outer Rock) are part of Ko Lanta’s National Marine Park and are named after a small furry animal (called ‘Rok’ in Thai), which can occasionally be spotted on the islands. Giant Monitor Lizards (often over a metre in length!) are regularly seen on the beautiful, powder-white sandy beaches, which are among the prettiest in Thailand.

Giant Red Gorgonian Sea FanEnormous Gorgonian Sea Fans, hard corals, interspersed with many colourful, soft corals, dominate the deeper areas on the east side of Ko Rok Nok. The marine life that can be found at Ko Rok varies from abundant and colourful reef fish to Black-Tip Reef Sharks, which can be spotted, cruising past the reef and if you’re lucky you can find a Hawksbill Turtle near the beach.

Ko Rok can be best described as a Coral Garden. The reef tends to slope gently downwards to a sandy bottom between 21 – 25 metres. You can expect to see plenty of Puffer Fish, Anemone fish and Snappers. If you look out into the blue, you might be lucky enough to spot an Eagle Ray or even a passing White-Tip Reef Shark.

Lined Surgeonfish Maya Bay, Ko Phi Phi, Ko Lanta, ThailandThe diving and snorkelling at Ko Rok is relaxed and scenic. There are great underwater photography opportunities and the visibility is usually superb.

The spectacular twin beaches, crystal clear water and abundant wildlife, above and below the water, make for memorable day for all the family.

We keep group sizes small to ensure you get the most out of each fun dive. This also reduces impact on our reefs. Our emphasis is on safety, fun and personal service within a relaxed and stress-free environment. You will find the atmosphere and service on our dive boats, beyond anything you have experienced before!
