Baby black tip reef sharks
One of the best places to see reef sharks while snorkeling is at the Surin Islands. This video was taken by snorkelers on the Sawan snorkeling liveaboard which runs 3 day 3 night trips to the Similan Islands, Surin Islands, Koh Bon and Koh Tachai.
Increasingly these trips spend more time at Surin and less at the Similan Islands, in fact sometimes they skip the Similan Islands all together. There are fewer other boats at Surin and the hard corals are beautiful. There is also usually the option to visit the Moken sea gypsy village.
Update July 2015. Sawan will no longer visit the Similan Islands on it’s 3 day 3 night trip, it will instead spend more time at the Surin Islands.
