Great Wall

Great Wall is a wall dive off Sipadan Island in Sabah, Malaysia, part of the marine park that made the island famous. The wall drops off sharply into deep water and is known for large numbers of green and hawksbill turtles, along with reef sharks and schooling barracuda and jacks that gather along the drop-off. Visibility is typically good given the site's exposure to open water near the edge of the continental shelf. Depths along the wall run from the shallows down well past recreational limits, so divers usually work the upper portion of the wall, and currents here can be brisk, making it a dive suited to those comfortable with drift conditions.
