Mai Khao is almost 10 km long combined with Nai Yang. It’s the only real gateway on the west coast of Phuket. Aside from JW Marriott Phuket Resort & Spa, the area is largely undeveloped with only a few tourist business. This lonely beach is another area where sea turtles come to lay eggs. It is also home to what the Thais calls sea cicada, which is a form of marine life. The water here is fine for swimming during the dry season, but the rainy season brings big waves and strong currents.
