The snorkeling sites of Koh Gai, the sandbar necklace of Krabi

Where the sea splits into three colors, the sandbars appear like magic, and snorkeling feels like walking into a postcard.

Koh Gai (เกาะไก่), also known as Chicken Island, is the iconic limestone island with a “chicken head” rock formation. Around it sit Koh Tup, Koh Mor, Koh Poda, and the quiet, underrated Koh Tang Ming — four islands connected by sandbars, coral gardens, and shallow turquoise water.

This is the bright, playful, sandbar chapter of Krabi — sunny, simple, and full of color.
