You push off from Tao Than Pier before dawn and the speedboat cuts a clean line through glassy water, the island silhouettes growing sharper as the sun climbs. Wind salts your face; the sea seems to pull you toward pockets of coral and white sand. By the time you step into the turquoise shallows at Koh Miang, the ocean has already begun to reveal its choreography of fish, bommies and branching coral.

History
The island name derives from the Malay word for nine islands; the chain’s granite outcrops were later designated a national park to protect marine habitat and tourism.
Conservation
The park enforces seasonal access and rules against touching coral or fishing—use reef-safe products, avoid single-use plastics and follow guide instructions to minimize impact.

Bring reef-safe sunscreen

Waters can be rough during transit; use waterproof cases for cameras and lock items in the boat’s dry storage.
Listen to guides for entry and exit
Follow snorkel briefings—proper entry, exit and finning techniques protect both you and the reef.
