More ways to explore the area's outdoor wonders
Dawn light spills across the Gulf of Thailand and the boat slips quietly from Mae Haad pier — the water a glassy sheet daring you into its shallows. The first stop, Tao Thong Bay, wakes with the tide: coral gardens unfurl under a surface that catches the sun, and small fish thread between stony fingers of reef. Moving on, Freedom Bay and Ao Leuk offer sheltered water where schools of baitfish scatter like thrown coins, and Shark Bay lives up to its name with graceful reef sharks patrolling the blue.
