Sheltered Samui cove for easy snorkeling and shallow reef.
Crystal Bay is Koh Samui’s sheltered shore cove, framed by granite boulders, small coral patches and easy water close to the beach. It is best for relaxed snorkeling and shallow shore time, with colorful fish around the rocks and the calmest water usually showing up in the morning window.

Shore access via public paths or resort frontage; use the calmest sheltered line when entering the water.
