Looe Key Reef

Located within the Florida Keys National Marine Sanctuary, offshore from Big Pine Key and Ramrod Key in the Lower Keys, Looe Key Reef is one of Florida’s most celebrated coral reef destinations. The site was formerly protected as the Looe Key National Marine Sanctuary and remains a highlight for snorkelers, scuba divers, and wildlife lovers today. Named for the British ship HMS Looe, which ran aground here in 1744, the reef is known for clear-water days, abundant tropical fish, and impressive spur-and-groove coral formations.

Because Looe Key is an offshore reef, visits are typically made by commercial snorkel and dive charters or by private boaters following sanctuary rules. Conditions, visibility, and trip availability can vary by weather and season.

Things to Do at Looe Key Reef

Snorkeling
Looe Key Reef is one of the Lower Keys’ signature snorkeling spots, with shallow reef areas accessible on many guided trips:
- Float above coral formations, sea fans, and patches of reef busy with tropical fish.
- Look for parrotfish, angelfish, sergeant majors, wrasses, grunts, and other common reef species.
- Local operators in the Lower Keys often include gear, basic instruction, and site briefings; offerings vary by company.
Scuba Diving
Looe Key is also a well-known dive site for certified divers and guided dive charters:
- Explore spur-and-groove reef structure, coral heads, sandy channels, and ledges where marine life gathers.
- Sightings may include barracuda, groupers, moray eels, nurse sharks, rays, and sea turtles.
- Depths and conditions vary, so divers should book trips that match their certification level and experience.
Wildlife Watching
The reef supports a rich mix of marine life and is one of the main reasons visitors come here:
- Watch for lobster, reef fish, rays, and sea turtles among the coral and hardbottom habitat.
- On some days, boaters and tour guests may also spot dolphins or seabirds in the surrounding waters.
- The protected reef is part of the broader Florida reef tract, making responsible wildlife viewing especially important.
Attend the Lower Keys Underwater Music Festival
This quirky annual event is closely associated with Looe Key Reef and helps promote reef stewardship:
- Participants snorkel or dive while music is broadcast underwater during the festival program.
- Event details, dates, and participating operators can change from year to year, so check locally before planning around it.

Coral restoration and stewardship programs exist throughout the Keys, though hands-on participation is usually arranged through specific organizations and may not take place directly at Looe Key.
