Nai Yang Beach, combined with Mai Khao Beach to the north, is the longest stretch of sandy beach on the island, covering 9 km. It is here that you will find giant sea turtles and throughout the dry season, October through February, this is where they come ashore to lay their eggs.
One of the activities of the Songkran Festival in April is to release turtles back to the sea. There is great swimming and snorkeling along this beach with access to Phuket Campground and Nai Yang National Park. There's great golfing east at Blue Canyon Country Club and the airport is out this way too.
