It lies to the south of Big Pine Key.
This reef is within a Sanctuary Preservation Area (SPA).
In August 1994, RV Columbus Iselin, a research vessel owned by the University of Miami, ran aground on Looe Key and damaged approximately 164 m2 (1,770 sq ft) of living coral and a larger area of reef framework.
In 1997, the University paid $3.76 million in natural resource damage claims to National Oceanic and Atmospheric Administration (NOAA).
In 1999, a restoration project involving placement of limestone boulders, pouring of concrete, and reintroduction of benthic species was undertaken by NOAA and its subcontractors.
