Infamous for its monthly full moon parties, Haad Rin Beach on Ko Phangan’s southern shore is synonymous with music, dancing and all-night beach raves. Backed by lush tropical rainforest, Thong Nai Pan Noi and Thong Nai Pan Yai are ideal spots to watch the sunrise, and Hat Than Sadet’s shady coconut trees offer respite on a sunny day. Meanwhile, Haad Khuat (also known as Bottle Beach) is a tranquil cove best for swimming and snorkeling.
