Similan day trip diving (Available only from 15th October to 15th May)
The Similan Islands National Marine Park is one of the most beautiful marine national parks in Thailand. The huge granite boulders offer amazing underwater scenery for scuba diving.
Consisting of 11 islands including Koh Bon and Koh Tachai, the Similans is perfect for diving in crystal clear water.
Surin islands and Richelieu rock is part of Surin national park, if you are an experienced diver and only on a day trip do you have a chance here, I would recommend you visit Richelieu rock (which was a top ten world dive site in the past).
With our Similan scuba diving day trip, you will dive from our comfortable day boat. Provided on board is water/tea/coffee, lunch, snacks, weights, tanks, life jacket.
70-90 km from the coast the Similan islands are quite far, so the fastest way to get there is with a speedboat transfer.
Where is the Best Similan Islands Diving Day Trip
There are several Similan Islands diving day trips to choose from, and guests need to be aware of a few things. These include the dive sites to visit, the traveling time, and the logistics.
We have Similan diving day trip boats to the ‘regular’ Similan islands, to Koh Bon, Koh Tachai, and to Richelieu Rock. All of them depart from Khao Lak, so if you’re staying in Phuket, please understand that coming to Khao Lak is necessary. Some of our Similan day trip diving boats depart from Khao Lak’s Tab Lamu Pier, and some others depart from a pier in Baan Nam Khem, nearly an hour north of Tab Lamu. If you are staying in Phuket the night before your Similan Island diving day trip, it is very difficult and expensive to join a diving day trip at the Similan Islands. Staying in Khao Lak the night before your day trip is very important.
