Fodor's Expert Review Thung Wua Laen Beach

Small islands that make up one of the world's strangest bird sanctuaries dot the horizon of this excellent 3-km (2-mile) stretch of curving white-yellow sand. Vast flocks of swifts breed on the islands, and their nests are harvested—not without controversy—for the bird's-nest soup served in Chinese restaurants throughout Southeast Asia. It's such a lucrative business that the concessionaires patrol their properties with armed guards. But all is calm and serene on the beach, which is just north of Chumphon. To get here, catch a songthaew on the street across from the bus station. Amenities: food and drink. Best for: solitude.
