Koh Kai is famously located about 8 kilometers from Ao Nang and owes its name to the shape of its strange rock formations, resembling a chicken's head.
The island not only impresses with crystal clear water and white sandy beaches, but is also considered one of the most spectacular snorkeling spots in the Krabi Sea.
Very close by are two other islands, Mo Island and Tap Island, whose sandy junctions are revealed at low tide, revealing the breathtaking scenery of a white sandbar in the middle of the sea. The place is called "Thale Waek" or "Sea Separated".
Entry to this area is 400 THB / Adult, paid cash to the Park Rangers. Different rates apply for Thai nationals, foreigners, adults and kids.
Regular Season prices. All rates in Thai Baht, incl. VAT.
