Nai Yang is just a five-minute drive south of the airport and is very popular with Thai locals. Here you'll find what beach life is all about. Fringed with casuarina trees providing picnic areas for locals, it's a shady spot for souvenir and food vendors.
Laid back to the extreme, most people who stay here find absolute relaxation. Parts of the of the beach are inside Sirinath National Park which also includes the reef at the north end of the beach.
