About Koh Tao

Assava Dive Resort is situated on the northern tip of beautiful Chalok Baan Kao, one of Koh Tao's most stunning beaches.


Ideally situated, the resort is close to supermarkets, viewpoints, ATM machines, medical facilities, bars and restaurants. From our beachfront dive shop location you will be able to enjoy the stunning view across the bay taking in the famous 'Grandfather Rock' on the headland and Angthong Marine Park on the horizon, the inspiration behind the book and film "The Beach".


The Beach

The beach is perfect for swimming and snorkelling, or alternatively just to relax and soak up the sun. In the evenings you can enjoy the 'The Cove Restaurant and Bar' where you are guaranteed some ecclectic tunes to accompany your cocktails. The perfect venue for meeting new friends.


The Name

The name "Assava" comes from the ancient Thai legend of a horse who represents strenth, prosperity and moving forward. Assava is also the abbreviation for the Thai owner's name "Assavachin" which is why the logo for resort has the seahorse to represent scuba diving within the waters of Koh Tao.
