Dive Site Overview

A classic Florida Keys spur-and-groove reef configuration defines this site, characterized by coral ridges (spurs) interspersed with sandy bottom channels (grooves). The spurs rise from 1.5 to 6 meters (5 to 20 ft) deep, creating cliff-like structures where marine life finds shelter.

These formations offer numerous crevices and overhangs, enhancing the habitat for various species. Fire coral is notably prevalent in several reef sections, contributing to the vibrant underwater topography and adding textural interest for divers. On the northwest side, coral heads and mixed rubble are found near a lagoon, providing distinct microhabitats.

In contrast, the south side gently slopes to a ledge around 20 meters (65 ft) before dropping further to 27 meters (90 ft) in some areas, presenting opportunities for deeper exploration for appropriately certified divers. Artifacts from an earlier brick lighthouse, destroyed in an 1846 storm, are present in the shallower parts of the reef, adding a historical dimension to the dive.

Spanning over 286 acres within a Sanctuary Preservation Area, this reef ensures a protected environment, limiting human impact and supporting ecosystem health.
