Although the Similan and Surin National Parks are closed May to October, there are still plenty of diving opportunities to take in Southern Thailand. We have put together a comprehensive list of some of the best diving options available to you while you visit Khao Lak, Phang Nga.


Khao Sok Lake, just north of Khao Lak, is a spectacular place to visit both above and below the water’s surface.

Thailand Dive and Sail have put together a great trip for 2 days and 1 night (although can be flexible on timings) departing from Khao Lak. Our Khao Sok Lake diving trip combines the best of the national park and the lake, taking in the stunning scenery where ever we go.


Diving in the emerald waters of Khao Sok Lake

Not only will you have the chance to dive this intriguing and eerie lake, a completely unique experience, but you will also get the chance to explore the jungle.

Diving in Khao Sok Lake is perfect for those looking for something a bit different.


Phuket Island is close to the south western dive sites, so for this reason we use it as a base from which to join the diving boats. The sites down there are interesting and varied; there is something for each experience level and even for non divers.

The best dive sites are Shark Point, Anemone Reef and King Cruiser. These 3 sites have a huge variety of marine life and some interesting underwater seascapes.

Koh Phi Phi has many different sites, many comprising of soft corals and beautiful sea fans. Racha Noi is a very similar site to the Similans, with many underwater granite boulders and Racha Yai is great for beginners as there are different sites on each side of the island with different difficulty levels.

Southern Thailand dive trips depart everyday, weather permitting.


Our second option for low season Thailand diving is a choice of one of 3 boats departing from Phuket on day trips.

We have chosen 4 of the best options for diving in the south western dive sites here in Thailand; the MV Latitude, MV Mermaid, MV Dive Asia II and the MV Kepsup. Each one of these boats offers something a little different with different dive sites. All 3 boats are kitted out for divers and snorkellers, the MV Latitude even has other activities such as kayaking for non-divers. This boat is ideal for those wanting to learn to dive.

Getting to Phuket from Khao Lak is easy, just over an hour and a half taxi ride away and you are there. This gives you plenty of time for naps before and after diving 😉



If you are wanting to spend a bit more time out on the water and want to immerse yourself in the diving world, then the 2 day 1 night MV Sai Mai is the option for you.

This low season we are introducing this overnight trip to our low season diving boats to give visitors to the area more diving options. The boat departs every Tuesday and visits the south western dive sites. It takes up to 6 people, so is an intimate and personal trip to join. The MV Sai Mai is also another good option for those wanting to learn to dive or continue their diving education.




At Thailand Dive and Sail we try to custom each trip to each individual diver. If you are interested in diving in Southern Thailand and would like to hear more information about these trips, or if you have any questions, get in touch with our Thailand diving experts.
