The dive sites at Ko Haa offer beautiful scuba diving and snorkelling with spectacular visibility. Diving at Ko Haa is suitable for divers of all levels.

Ko Haa’s highlights include The Lagoon, The Cathedral, and other caverns, inter-connected chambers and swim-throughs.

We make trips to Ko Haa every day during high season on board our luxury dive boat MV Moskito.

Ko Haa, which means ‘Five Islands’ in Thai, has a central lagoon area that is ideal for beginners. It offers a safe and relaxed starting point for you to take your first underwater breaths and there are some extremely friendly little Porcupine Puffer Fish, ready to make your acquaintance in the large, sandy bay area. The bay slopes gently onto the reef allowing you to progress into your first dive effortlessly.

The marine life that can be found at Ko Haa varies from rare Ghost Pipefish measuring only a few centimetres, to an abundance of Octopus hiding amongst the rocks and crevices. A Hawksbill Turtle is often seen swimming amongst the pristine coral. Manta Rays, Marble Rays, Eagle Rays and even Whale Sharks are spotted here occasionally.

You can’t predict exactly what you’ll see, but it’s always a pleasant and rewarding surprise!

One of Ko Haa’s highlights is the series of caverns and swim-throughs. The largest cavern has three chambers and is known as The Cathedral. The first two chambers are connected by a shallow swim through at about 9 metres.

Ko Haa Island #1 (Ko Haa Nung) has various chimneys and other systems to explore. You can find banded sea snakes, lionfish, nudibranches, frogfish, harlequin shrimps, many other crustaceans and beautiful cowries. If you take a look out into the blue, you can find huge schools of silverside fish, glassfish, barracudas and travellie.

The clear waters and consistent visibility of 25m+ make Ko Haa an un-forgettable diving destination.

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!

Our experienced Divemasters know the dive sites extremely well, and will be happy to discuss what you would like to see, and the type of dive or snorkel experience you would like to have. Each dive is personally planned with the divers in each group, to ensure you enjoy each and every dive you make with us.

A full briefing is provided at each site, with helpful tips on what to look for, safety information, and the most interesting places to visit.
