Nai Thon beach lies about 15km south of the airport. The beach is still quite undeveloped and is a nice quiet place to sit in the sun or take in a swim.
This pristine beach is a great place to get away from the crowds. However, the beach is not completely deserted, and there are a few sunbeds available for hire. There are also a few small restaurants that serve fresh seafood and local dishes.
Nai Thon is part of the Sirinath Marine National Park, which also includes Mai Kao and Nai Yang, the next beaches along to the north. The area was declared a national park in 1981 to protect the sea turtles that lay their eggs here from November to February.
Part of the reason Nai Thon has managed to remain so peaceful is that it is quite isolated. The road leading to the beach winds through jungle and rubber plantations as well as over a few hills. There are a few places to stay, including some bungalows and guesthouses.
