The practical route is a long offshore boat run to Koh Tang, with operator logistics handling the trip and pickup.
Rocky Ridge is a remote Koh Tang boat dive at the island's southern tip, where a rocky ridge and big fan corals pull in the area's richest marine life. The site feels like a deep rock wall more than a simple reef, with open-water exposure that rewards calm conditions and steady trim. It suits divers who are comfortable with a long boat trip, deeper water, and a destination-style dive.
