Mai Khao Beach is Phuket's longest beach that spans for about 11km. The area is relatively quiet, and even undeveloped in some places as it is part of the Sirinat National Park. You won't find a lot of nightlife or shopping in these locations, but they make good alternatives to the hustle and bustle of the beaches further south. The place is close to Phuket International Airport, and also close to Sarasin bridge which connects Phuket to mainland Thailand.
