Chain Wall - Lighthouse Reef
Chain Wall sits just west of Half Moon Caye, a solid alternative when the main wall is busy. We’ve always found the visibility here reliable, often pushing past 30 meters on a good day, making the wall’s sheer drop quite impressive. Look for barrel sponges clinging to the overhangs and keep an eye out in the blue for reef sharks cruising by. It’s a pretty straightforward wall dive, good for any certified diver looking for a relaxed drift and consistent encounters with the usual Caribbean suspects.
