What Are the Best Dive Sites in Koh Lanta?

Koh Lanta lies within Krabi province, which is on the shore of the Andaman Sea – situated at the western coast of Thailand’s central region. Here, you will discover scuba diving spots that are some of the best in the world, all close to wonderfully luxurious resort accommodation.

There are an abundant collection of spectacular dive sites to enjoy in Koh Lanta, including some of the following:

Twin Lotus Resort and Spa
  • Hin Daeng: Known as ‘Red Rock’, this unique geologic formation drops to as low as 70 m. You will see bright red corals teeming with life, including some giant moray eels. If you look out further afield and you will see patrolling barracudas and curious batfish that swim very close to divers.
  • Hin Muang: Known as ‘Purple Rock’. Here you can see beautiful coral, including creatures like anemones – after all, Koh Lanta is right by the famous Anemone Reef between nearby Phuket and Phi Phi. The depths and currents of this dive site make it suitable for more experienced divers.
  • Koh Haa: Another nearby island, Koh Haa has some great opportunities for snorkelers and divers. A calm area called ‘The Lagoon’ is ideal for beginners, and you can see many gentle creatures including turtles swimming amongst the dense coral – sheltered by the surrounding rocks.

Koh Haa also has some caverns that are excellent options for budding cave divers. One such dive spot is known as ‘The Cathedral’, which gives you an amazing view of a curved ceiling – with scattering reflections of sunlight piercing through the clear water and bouncing off the top of the cavern. It is truly mystical.

Aside from the dive sites, at the luxury Twin Lotus Resort and Spa, you can easily relax between dives – or take a quick dip in the pool if you want more swimming! We offer incredible scuba diving holidays to several destinations in Asia, Thailand is a key destination but Koh Lanta is a cut above many of the dive spots available.

What Are the Conditions Like When Diving in Koh Lanta?

Thailand’s warm waters make it a haven for all sorts of activities, and diving is surely one of them. The diving season is during the non-rainy times of the year, which is usually March until October. Overall, conditions are very good for all skill levels – but Koh Lanta is also a great option for beginners.

Further details on the conditions you can expect while diving in Koh Lanta include the following:

  • Temperatures: Thailand’s temperate climate makes it a draw for people both in and out of the water. As such, you can expect very comfortable temperatures. Typically you will see an average temperature at most dive sites ranging from 28-31°C – very comfortable for swimming and diving
  • Currents: The currents for open water dives are stronger than shore dives. However, for an open water dive, they are still quite mild. Currents also vary depending on the depth of different dive sites. However, many sites are ideal for beginners and scuba divers with more experience.
  • Visibility: The glass-like waters of southeast Asia are a sight to behold from above or below the shoreline. Much of Thailand’s treasured coast and islands are protected by strict conservation laws. Expect visibility of around 15 m to 40 m – depending on the location.

Open water dives will require PADI Open Water diver certification, which means that if you want to experience shark diving with the gentle whale sharks in the area – you may need to visit a dive centre to qualify before travelling. 

It is understandable to have reservations about your current skills, but we can provide an extremely fun diving opportunity for all levels of skill – as well as preparatory courses for those keen to safely experience a particular type of dive.
