A reef wrapping a peninsula near Mononaftis that steps down in levels from 6 m to 30 m at its deepest point on the northwest side. The feature divers come for is a tunnel: the entrance is at 14 m and the exit at 8 m. Shallow ground for beginners and deeper rock for certified divers, on the same dive.

The dive
The reef wraps the peninsula in terraces, so you choose your depth rather than follow one contour. It starts at 6 m near the rock and steps down, level by level, to the deepest ground on the northwest side at 30 m. That range is what makes the site work for mixed abilities: the shallow terraces are a dive in their own right, and the deep side is there for anyone certified to use it.
The tunnel is the set piece. The entrance is at 14 m and the passage runs up through the rock to an exit at 8 m, so you go in deep and come out six metres shallower than you went in. Take a torch and keep your trim settled: it is an overhead, however brief. After that, the shallow terraces will absorb whatever gas you have left and the safety stop is over rock rather than in blue water.
