Ko Tao (เกาะเต่า), literally Turtle Island, is an island in the Gulf of Thailand in the south of Thailand in Surat Thani Province, Thailand.
Historically, it was once the detention place for political prisoners similar to Ko Tarutao of Satun Province, but today it is a great place for divers or anybody who want to get away from the hustle and bustle of Ko Samui and want more than the Full Moon Party on Ko Pha Ngan. Ko Tao is a great place to learn how to dive. There are hardly any currents and a wide selection of dive sites and dive shops, schools and resorts. Activity options are growing outside of diving and the food and nightlife options are some of the best in the Gulf of Thailand.
Ko Tao is a small island with over a 100 000 visitors per year. To minimize your impact on the eco-system, notice that there are no garbage disposal facilities, so everything that can't be burned has to be taken away. Try to avoid plastic bags that are given out for every purchase you make. There is also no department to clean the roads or other public areas, so don't dump your waste on the open landscape. Water is scarce and electricity expensive, so don't waste them.
Peak seasons in Ko Tao are from December to March and July to August. It is quite popular destination amongst Thais also, so it can be nearly fully booked on Thai holidays.
See
Take a bike around the island. Shark Bay is a good place to go snorkeling for the day (don't worry too much about sharks, they are only small black-tip reef sharks). Koh Nang Yuan, Freedom beach, Laem Thian, Mango Bay, Hin Wong Bay and Tanote Bay are good day excursions, accessible by road or boat. If you rent a scooter, be prepared to turn around or continue by foot since some roads (e.g. to Mango Bay) may be in such condition that you need a dirt bike or a car to ride them. Some beaches are private, but a boat can take you snorkeling to those bays also.
However, to see the best places, go by foot as some are inaccessible to motorists. There are a number of good viewpoints around the island such as John Suwan mountain viewpoint in the South of the island, Two View in the center and Fraggle Rock in the North.
Do
Scuba diving is still the biggest attraction on Ko Tao. Diving in Ko Tao is easy, fun, and you can see turtles, stingrays, barracudas, lots of small fish, reef sharks, and there is a very small chance of seeing a whale shark.
At Chumphon Pinnacle you are likely to see juvenile bull sharks which have, until recently, been misidentified as grey reef sharks. Don't worry, the bulls are curious but not aggressive and for many years literally thousands of people have dived this site without a single shark related incident.
Nearly any time of the year except November is good diving weather in Ko Tao and visibility can exceed 40 meters. Average visibility is around 15-20 meters. In November visibility is reduced and the seas are choppy, but diving is good by the standards of many other destinations.
It is possible and perfectly comfortable to swim and dive without a wetsuit year round. However, as with most diving, a wetsuit is recommended to help reduce risk of cuts or injury. Avoid contact with coral reefs!
