Two pristine beaches stretch along Phuket’s northwest coast within Sirinart National Park, offering something increasingly rare on this popular island – protected shoreline free from commercial development. Mai Khao and Nai Yang beaches remain largely untouched, serving as crucial nesting grounds for sea turtles while providing visitors with the kind of natural coastal experience that once defined Thailand’s reputation as a tropical paradise.
Crystal-clear waters lap against soft white sand backed by casuarina trees that provide natural shade throughout the day. The beaches here are perfect for swimming, with gentle waves and shallow areas ideal for families. You’ll hear the rustle of pine-like casuarina needles in the sea breeze and smell the fresh salt air mixed with tropical vegetation. Snorkeling reveals colorful coral formations just offshore, while the northern sections offer excellent spots for peaceful walks along seemingly endless stretches of sand. Between October and February, lucky visitors might witness sea turtles coming ashore to nest under cover of darkness.
Tranquility defines the experience at Sirinart National Park. Unlike Phuket’s busier beaches, these shores maintain their natural rhythm, with only the sound of waves and wind through the trees. The absence of jet skis, loud music, and aggressive vendors creates a meditative environment where you can actually relax and reconnect with nature. Families appreciate the safe swimming conditions, while couples find romantic sunset spots along the quieter northern stretches of Mai Khao beach.
Visit during the cooler months from November to March for the most comfortable weather and calmest seas. The park is easily accessible by car or taxi from Phuket Airport, which sits adjacent to the northern boundary. Bring reef-safe sunscreen, plenty of water, and snorkeling gear if you have it. Since facilities are limited within the park, pack snacks for longer visits. This free natural sanctuary proves that Phuket still offers authentic beach experiences away from the crowds.
