This area is a fisherman's nightmare — they only ever catch Bermuda Chubb, not a particularly tasty fish — so it is avoided in favor of other areas. Their nightmare is our dream. To the southeast of the pin, the miniwall is a mishmash of tunnels, canyons, and archways packed with the namesake Bermuda Chubb. Look in the narrow canyons for Tarpon — with shiny scales and grumpy faces, these large and benevolent fish are easy to photograph as they remain completely unbothered by divers. In the gloomy recesses, look for rarer critters such as the Slipper Lobster, a creepy-looking throwback to prehistoric times.

To the north, the reef opens up with large open-sided overhangs and tall fingers of coral standing on the seabed. In the right season, vast numbers of tiny juvenile fish swim just inches from the bottom and across every coral head. Look out into the blue from time to time — Colliers Bay has an excellent record for sightings of giant Loggerhead turtles, and there is nothing quite like watching these prehistoric creatures cruising about the reef.
