West of Eden is a big-boulder island dive built around giant granite rocks, canyons, and coral slopes. The shallow start gives way to a longer route across walls, channels, and coral-covered boulders, with strong fish activity and current often shaping the line. It is a classic west-side site for divers who want structure and color rather than a flat reef.
