About This Anchorage
Koh Kradan is widely considered one of Thailand's most beautiful islands — an uninhabited (no permanent residents) island within Hat Chao Mai National Park with extraordinary clear water, white sand beaches, and healthy coral reefs. The anchorage off the northern beach is in clear turquoise water over sand and coral. Annual underwater Valentine's Day wedding ceremony attracts significant attention. Snorkeling directly from the boat is outstanding.
