          From the moment you arrive at Koh Tao Scuba Club you will be treated to a team of professionals that love to dive and excel at providing you with the best experience you could possibly gain whilst diving around Koh Tao. Sun Smile is the name of the boat and since they do not share her with anyone they get to choose the dive sites they wish to visit on a daily basis. Koh Tao Scuba Club provides you with a diving experience which is as close to boutique as you could possibly get, without being boutique (at the end of the day, if they do everything for you, you will never learn the correct way to manage your own equipment). Since Koh Tao is so small you will find them perfectly situated at the south end of Sairee Beach, therefore access to any location during your stay whether that is the heart of Sairee or Chalok is only a matter of a few minutes’ walk along the beach. They have a vast array of accommodation available within the Mae Haad area, which are ideally placed guaranteeing a peaceful night’s sleep away from the late night bars. All you need to bring is a smile and a sense of adventure.
