When it comes to scuba in Thailand there is only place that is worldwide known for great diving - the Similan Islands in the Andaman Sea. We have secured a perfect slot in the best season and right over Easter allowing for a perfect break with minimal time off work.


Join Insider Divers to the Similan Islands in Thailand. Home to the healthiest reefs and the best marine life in Thailand. The world famous marine park Mu Ko Similan has been under protection since the eighties and has therefore maintained good reef cover and plentiful fish stocks.

Reef sharks and leopard sharks are very common as well as many schooling fish. But the famous pelagics such as Manta Rays and even the Whaleshark can be spotted here on occasion as well.


The key season is December to May and particularly in March and April we have the clearest, warmest and calmest waters allowing for the best diving that this region has to offer.


During our trip we will dive mostly 4 times a day including night dives so on this 4 night trip we will manage to do 14 dives, weather permitting.

We will dive Koh Bon, Koh Tachai and of course Richelieu Rock as well as Khao Lak wrecks. All of these are of cours weather permitting but April is one of the calmest months of the year.

Check out this video to see a bit more about our vessel "The Junk" and the kind of diving you can expect here.


The Junk is part of the World Wide Dive and Sail group that owns the brands Blue o Two, Master and Siren. You can expect to be perfectly catered for in this stylish converted wooden Chinese sailing junk with great food and lovely ambiance. Diving of two speed boats we will be diving very comfortably. Every room as individual aircon and private batch. For those wanting to save a few bucks or travel with friends we have a quad and a triple available.
