Koh Tao, Thailand
Koh Yang Nuan
Koh Tao and Koh Yang Nuan are islands were you can do some diving and snorkeling in the Gulf of Thailand. If you’re trying to get to these islands, your best option is to take a trip from the island of Koh Samui to get there. Koh Tao is one of the areas in Thailand where you can possibly see whale sharks (and regular ones!), and you will see lots of brightly colored tropical fish in the shallower snorkeling areas.
Given the recent announcement that the Thai government is considering restricting access to Koh Surin and The Similan Islands, it will be interesting to see if similar steps are taken to protect the coral for human development and other environmental pressures in other aquatic marine parks.
