The coast of the Gulf of Thailand—which includes the southern and western shores of Thailand and the southwestern edges of Cambodia and Vietnam—is home to some of Southeast Asia’s most celebrated beaches and islands. Paradise is easily to find in these parts; popular spots include the palm-studded trio of Koh Samui, Koh Pha Ngan, and Koh Tao islands and the kaleidoscopic coral reefs of the Ang Thong National Marine Park.
