Ao Suthhep is a broad shallow coral bay on Surin Tai.
Ao Suthhep is a broad coral bay on Surin Tai with a long shallow reef that stays close to shore. The site is known for dense hard coral, especially table, staghorn, finger, and fire coral, plus reef fish moving through the coral blocks. It is best in the park's open season, when the bay is calmer and the water is clearer for slow snorkel or easy reef diving.

Safety Notes
Protect fragile hard coral, keep buoyancy tight in the shallow reef, and avoid the site when wind or swell lifts surge.

Follow national-park rules and seasonal closure dates; park fees are part of the visit on organized trips.
Community notes to help plan your visit.
Scuba Diving
Shallow hard-coral reef with easy navigation and enough structure for relaxed reef dives when sea state is steady.
Freediving
Good for calm-water freediving over coral blocks and shallow reef structure, with careful buoyancy and fin control.
Snorkeling
Best as a slow reef snorkel with careful finning over the coral garden; avoid standing on or brushing the reef.
