Looe Reef – Lower Keys & Key West

Site Overview

Looe Reef is a pristine coral sanctuary in the Lower Florida Keys featuring healthy elkhorn coral formations, diverse reef fish communities, and extraordinary snorkeling and diving conditions in shallow protected waters. The reef is part of the Florida Keys National Marine Sanctuary with strict protection ensuring exceptional coral health and fish density compared to unprotected reef systems throughout the Caribbean. Massive elkhorn coral colonies create dramatic underwater landscapes with branching formations reaching toward the surface providing habitat for hundreds of tropical fish species including colorful parrotfish, angelfish, and juvenile reef sharks. The shallow depth of one to ten meters makes Looe Reef accessible to snorkelers and beginner divers while still rewarding experienced divers with the opportunity to observe healthy coral ecosystems that are increasingly rare throughout the Caribbean region. Seasonal visitors include sea turtles feeding on the reef, spotted eagle rays gliding along the reef edge, and dolphins occasionally passing through the channel creating unforgettable surface interval encounters. The sanctuary protection has allowed the reef ecosystem to recover and thrive with coral coverage exceeding most Caribbean reef systems and fish populations that include commercially important species at densities rarely seen on unprotected reefs. The reef's shallow profile and protected location create ideal conditions for coral recruitment with new colonies establishing annually expanding the living reef structure and providing habitat for an ever-increasing diversity of marine organisms.
