Billy's Reef - Cape Town & Western Cape

Billy's Reef, tucked away in the Cape Town area, offers a decent dive for those exploring the local scene. It’s a series of parallel ridges, running northwest to southeast, with the higher bits of reef concentrated centrally and to the north. We’ve found the layout makes for some interesting navigation through the deeper, sandy-bottomed gullies, often crisscrossed by smaller reef sections. While it might not blow your hair back like some of the bigger-name sites, you’ll usually spot some interesting nudibranchs if you look closely, and the resident shy reef fish are always fun to try and spot. It’s a good choice for divers looking for a relaxed exploration rather than a high-octane drift.
