With 9km (5 1/2 miles) of snowy white sand this is Phuket's longest beach. Its crystalline sands are devoid of litter and it is one of the island's two beaches that remain in a pristine state. The adjoining mangrove area is now preserved as the new Sirinat National Park and includes a visitors' centre. Dine at one of the small thatched restaurants on the northern end. They serve excellent seafood at very low prices. Construction has been banned here, so there are no accommodations available. It is the only beach in the area filled with wide Cicadas and they are found profusely near the airport. The sea Cicadas are a kind of insect blending harmoniously with the colour of the sand. Villagers catch them to eat.
In the beginning of December 2006, Thailand launched the first of 22 tsunami-detection buoys to be positioned around the Indian Ocean as part of a regional warning system against giant waves caused by earthquakes under the sea. The satellite-linked deep-sea buoy will float 1,000km (620mi) offshore, roughly midway between Thailand and Sri Lanka.
