Khao Lak snorkeling recommendations

Snorkeling tours from Khao Lak to the Similan Islands and Surin Islands

Similan Islands tours

Crystal clear water surrounding nine uninhabited granite islands. Popular with scuba divers and snorkelers. Biggest schools of fish, turtles, eels, hard and soft corals.

Beautiful beaches with viewpoints to climb to get some amazing photos.

Surin Islands tours

Snorkeling at the Surin Islands

The Surin Islands are great for beautiful beaches, healthy soft corals, baby reef sharks and turtles. Plus the chance to see the native Moken sea gypsies.

The Surin Islands are a less visited destination than the  Similan Islands.

Koh Bon tours

Manta Koh Bon

Koh Bon is a tiny limestone island about 20km north of the Similan Islands and part of the Similan Islands national marine park. It’s popular with dive boats because it’s a manta ray feeding and cleaning station.

The best way to go to Koh Bon is by liveaboard (better chance to see a manta ray) but a day trip is also available.


Khao Lak snorkeling tours are done by day trip boat (speedboat or slower dive boat) or on a longer liveaboard trip. Tour options include the Similan Islands, Surin Islands, Koh Tachai, Koh Bon and Richelieu Rock. These are the best reefs in Thailand with the most fish and the biggest fish.

The Khao Lak snorkeling season is November to April. That’s when the north east monsoon brings good weather, there are virtually no boats running from May to October, Khao Lak is very quiet during the summer.

  • Phi Phi Islands – a Khao Lak low season tour.
    If you are staying in Khao Lak from November to April you are closer to the Similan and Surin Island national parks than to Phi Phi. Phi Phi is reached by driving to Phuket (1.5 hours) and then getting a boat to Phi Phi.
    This is an option for you if you are in Khao Lak during the summer months of May to October when the Similan and Surin Islands are off limits.
