Located in Phru Nai subdistrict, to the north-east of ko Yao Yai, Ko Khai is made up of three small private Islands, namely Ko Khai Nai, Ko Khai Nui and Ko Khai Nok. These islands resemble a fried egg from an ariel view, and they occupy the ocean space between Ko Sirae (Phuket) and Ko Yao Yai (Phang-nga). The water is crystal clear with stunning coral reefs, making this island popular with Phuket tourists, as it’s a just a short 15-minute Boat ride away. The main activities available on the Island are checking out the beaches, snorkeling among the coral reefs, and taking pictures with the intriguing, curved rock formations.
