Long Reef is an offshore coral reef known for easy depths and a steel schooner that grounded here in 1966. It’s a classic Biscayne experience: clear water, spur‑and‑groove coral formations, and fish everywhere—without needing to dive deep.
Expect vibrant hard and soft corals, big sways of gorgonians (sea fans), and patches of fire coral. The shallow shipwreck rises close to the surface and is draped in life. Common sightings include schools of yellowtail snapper, parrotfish, blue tangs, colorful sponges, and the occasional nurse shark cruising by.
Few spots combine a shallow, beginner‑friendly reef with an accessible wreck that’s lively and easy to navigate. The spur‑and‑groove structure creates mini alleys and sand channels that concentrate fish and make for varied, photogenic terrain.
This is a boat‑only destination with no facilities. Use the provided mooring buoys and do not anchor—both the reef and the wreck are fragile. Bring all your water, snacks, and gear; pack it out when you’re done.
Depths hover roughly 10–20 feet, ideal for long, relaxed snorkeling or shallow dives. Water clarity changes with weather and swell, so check marine conditions before committing. The site draws tour boats and private vessels; expect more traffic during popular times.
Aim for non‑peak times to dodge boat traffic, and plan around favorable wind and seas for better visibility. Weekdays typically feel quieter than weekends. If conditions look stirred up, give it a day and try again—this site shines in clear water.
Stay off the coral and wreck, control your fins in the surge, and keep a respectful distance from wildlife. Use reef‑safe sunscreen and secure all loose gear so nothing drifts onto the reef.
