Set in the middle of Phang Nga Bay, Koh Yao consists of two large islands, Koh Yao Noi and Koh Yao Yai, surrounded by many smaller islands. Yao Noi is covered by forests with a large variety of birds, monkeys, monitor lizards, barking deer as well as very colorful insect life.

From the coast line with nicely shaped beaches and rocky headlands one can enjoy spectacular views of the surrounding limestone formations that are characteristic to Phang Nga Bay.

Koh Yao Noi is the most populated of the two islands with quiet and picturesque fishing villages and Ta Khai, a small town with minimal source of supplies.
