Sitting along the southern coasts of Phuket, Nai Harn Beach’s laid back vibes draws family-friendly crowds seeking a beach hangout away from Phuket’s busier coasts. Its tranquil shores, lined with sunbeds and rows of casuarina trees, are perfect for a lazy afternoon of sunbathing. Beach-goers seeking respite from the tropical heat may cool down with a dip in Nai Harn’s calm, turquoise waters.
