Koh Haa island Thailand – How to get there
This part of Thailand’s scuba diving region is located in the southern Andaman Sea. It can be found between the Phi Phi Islands and Hin Daeng – Hin Muang.
The liveaboard trips depart in the evening from Phuket. There is a minibus service to collect scuba divers from their hotels or from Phuket airport on Phuket island. But there is an additional charge for this service.
Mostly visited by liveaboard cruises, but it is also frequented by day-boats too. Koh Haa’s lagoon is enjoyed by scuba divers and snorkelers alike. You can pick out the liveaboard dive boats going to the Phi Phi Islands that also visit Koh Haa below. Or continue reading to find out more about the two Koh Haa liveaboards reviewed in this article below.
The meaning of Koh Haa in Thai is ‘five islands.’ But actually there are six islands in total.
This tiny group of islands is located about 25 kilometers (15.5 miles) west of Koh Lanta Island.
Koh Haa scuba diving
The Channels that run between the Koh Haa islands are over 50 metres (164 feet) deep in places. The visibility is normally clear, making for good blue-water diving in warm waters.
Koh Haa falls within the Mu Koh Lanta National Marine Park and diving there requires a licence.
The lagoon itself ranges in depth between 3 metres (10 feet) in the centre to around 12 metres (40 feet) at the edges.
The area is ideal for all diver levels, which includes both beginner scuba divers to advanced divers alike.
At some of the other dive sites in the region, dive depths will range from 5-20 metres (16-66 feet). There are currents at certain points of the islands, but currents are extremely gentle which allows for beginners to dive there too.
However, the conditions and the sea state can be choppy at times when the winds come in from the Indian Ocean.
Koh Haa caverns and swim-throughs
Koh Haa is known for scuba diving in caverns, which have large entrances and are safe to enter. The exciting part about these caverns is that you can surface inside. When you do you can see the ancient stalactites which hang from the cave ceiling.
In addition to the fantastic and exciting caverns, there are also swim-throughs to enjoy too. These swim-throughs lead away from and then back to the main cavern.

Koh Haa lagoon – what to see
As with many dive sites around Thailand, Koh Haa is a place to see plenty of interesting sea creatures.
Sea creatures around Koh Haa lagoon:
- Hawksbill turtles.
- Stingrays, including Kuhl’s blue-spotted stingrays.
- Blacktip reef sharks in the mornings and early evening.
- Moray eels in abundance.
- Spot yellow box fish.
- Banded sea snakes.
- A good spot for plenty of octopus.
- Trumpet fish.
- Great macro life including nudibranchs and coral reef fish.
- Plenty of soft corals with large Gorgonian fans and sponges.
- Pelagic fish are often seen at the point of the islands in the fairly strong currents there, including mackerels and cobias.
- For the patient scuba divers and keen underwater photographers, there’s the chance to see seahorse, frogfish, ghost pipefish and sea moths.
Best time to visit Koh Haa – when’s the dive season?
The best dive season for Koh Haa is between November and April. This is the time when the weather is at its best. But also the seas are usually calm at this time of year.
The water visibility can reach as much as 30 metres (100 feet) at this time of year.
The water temperature is a balmy 29-30°C (84-86°F) from February through to April.
During the rest of the months of the year, the Koh Haa islands are officially closed to scuba diving.
During this season there are strong winds in the region, which tend to whip the the seas up into a storm. These winds bring large waves and at times heavy rains too.
Not that this makes much difference, as diving is not permitted, but the visibility can drop to as low as 5-10 metres (16-33 feet) at this time of year.
