Chimney is a well-known Dog Islands boat dive built around an unusual reef formation with a long swim-through as the signature highlight. Most dives are planned by approaching the structure, passing through the tunnel-like section, and then continuing along the surrounding reef to explore the colorful surfaces and crevices. A dive light is widely recommended to bring out the vivid colors and details inside the swim-through. Because the main attraction includes an overhead environment, plan for controlled buoyancy and careful finning to maintain clearance and avoid contact with the reef.
