About Coral Cove Beach

Coral Cove punctuates the southeast shore of Koh Samui, Thailand's second-largest island in the Gulf of Thailand, where a 150-metre crescent of fine sand sits crowded with rounded granite boulders – the same formation as the famous Hin Ta and Hin Yai rocks further south. Five kilometres north, Chaweng Beach runs six kilometres of resort strip and white sand, while Lamai Beach stretches mellower four kilometres south. The sea holds 28–29 °C from January through September, with Samui airport 25 minutes by Route 4169.
