Lanta Dive Site Tips – Insider Knowledge from the Locals!


Ko Haa is a fabulous group of dive sites. They consistently offer the best diving in the area with superb visibility and fantastic diving conditions. Take several days to explore and experience the best sites. Although less well-known and publicised than Hin Daeng & Hin Muang, they offer more consistent diving, a greater range of sites and marine life with an equally good chance of seeing Whale Sharks. Great for underwater photography.

These sites are for experienced, advanced divers only. Conditions can be unpredictable with strong currents, variable visibility and require diving at depths greater than 18m. You must have a minimum of 25 dives, a deep adventure dive or advanced certification and have dived recently. We recommend you make your first day’s diving at one of the local sites before venturing out to these sites. Great sites for nitrox.

These two diving and snorkeling destinations are both less well known than the other sites in the area and too far south for many of the Saladan dive operators to visit. This means that we are usually the only dive boat at these sites. Offering different types of coral and marine life than other sites in the area, we are still discovering new sites and new species as we dive these spots. Great for mixed groups of divers and snorkelers.


Open all year round – we offer diving and snorkeling trips every day!


High Season:
Throughout high season (October – April), Scubafish operates 2 separate dive boats each day, visiting 2 different dive destinations. This allows the chance to visit the widest possible range of dive sites during your visit to Ko Lanta. Take a look at our Trip Schedule to plan and maximise your diving opportunities.

During high season, we depart directly from the beach in Kantiang Bay in the south of Ko Lanta, saving you hours of valuable holiday time. We know your holiday time is precious and we want to make sure you get the most out of it!

Please note: during the high season there is an entry fee to the Ko Lanta National Marine Park of 600 THB per person per day when you dive, snorkel or enter applicable sites.

Low Season:
During the low season (May – September), we operate a more flexible schedule, offering trips where dive conditions are the most favourable. We offer trips to Ko Haa, Ko Rok, the Southern Islands and Hin Daeng & Hin Muang (weather permitting). We are able to join dive boats departing from the north to visit Ko Phi Phi.

During the low season, we moor our boats in Lanta Old Town on the East side of the island. We aim to offer trips every day, however there are some days when, due to the wind and waves, we are not able to take the boats out.
