One Finger Rock

A flat coral plateau at 12 m (40 ft) that drops sharply to 120

A Douglas Bay site built on a flat plateau at 40 feet (12 m) where sand, sponges and corals run into each other, and which then drops sharply away to 120 feet (37 m). Cabrits Dive Centre describes sand and big coral patches at the foot of the drop, teeming with thousands of fish including some very large snapper.

The dive

The plateau comes first: Cabrits Dive Centre puts it at 12 m (40 ft), a flat run of sand mixed with sponges and corals, easy ground to cover and easy ground to navigate. Then it ends. The plateau drops sharply away to 37 m (120 ft), and that edge is the feature of the site, giving the dive a clear line to follow and a clear place to turn around.

At the foot of the drop the centre describes sand and big coral patches teeming with thousands of fish, including some very large snapper, which is the reason to go over the edge rather than stay on top. The published range, 35 to 120 feet or roughly 10.5 m to 36.5 m, covers the whole structure, so the deep patches go first and the rest of the dive runs back up on the plateau.

Season follows Dominica: November–May gives calmer seas and the best sperm whale sightings; September–October bring the heaviest rain and hurricane risk.

Know before you go

  • The plateau edge falls to 36.5 m and a slope that steep pulls a dive deeper than planned; set the maximum depth before dropping over it.
