Natural AttractionFowey Rocks Lighthouse
Five miles offshore, a solitary 50-foot tower marks Miami's deadliest reef. Built 1875, still the "Eye of Miami."

The hull of the British steamer Lugano lies 25 feet below the surface on Long Reef, a three-story vessel frozen mid-recovery from its March 1913 grounding. On a stormy passage to Cuba carrying fine silks and wines valued at $1 million, Captain Penwill ran aground in heavy seas, stranding 116 passengers and a dedicated salvage effort that would make headlines across the Keys. Wreckers removed cargo and attempted refloating for over a month, but by April the hull was abandoned—its broken mast and stack still visible underwater today as a maritime archaeology site protected within the park.

Boat access required; snorkeling possible for swimmers; diving equipment and certification needed for close examination.
Submerged British steamer hull, visible structure at 25-foot depth, broken mast, cargo hold, deteriorated deck sections.
Steel and wooden hull sections, evidence of cargo removal, mast remnants, marine life colonization (corals, fish), reduced visibility depending on water clarity and tidal conditions.
One of the largest vessels wrecked on Florida reefs at the time of incident (1913); documented salvage history with U.S. Customs involvement; protected archaeological site with interpretive value for maritime history.
April through November for calmest seas and best underwater visibility. Avoid December-March when rough Atlantic conditions make boating hazardous.
Underwater hazards: nitrogen narcosis at depth, strong currents around reef, limited visibility in poor sea conditions, hypothermia risk in winter water (73°F). Divers must maintain 100-yard distance from other marine life per NPS policy. Surface intervals required for safe decompression. Do not dive alone.
One of the largest vessels wrecked on Florida reefs at the time of incident (1913); documented salvage history with U.S. Customs involvement; protected archaeological site with interpretive value for maritime history.
Maritime archaeology (1913 salvage operations documented by U.S. Customs), conservation biology (wreck as artificial reef habitat), marine corrosion mechanics on steel and wood in salt water.
Launch your own boat from Convoy Point ramp near the parking area, or book a guided tour through park-approved operators. Head approximately 7 nautical miles to Long Reef. GPS coordinates: 25.443983,-80.119517.
Other reef wrecks accessible via boat from the same launch point; Birding at Elliott Key and Birding at Convoy Point.
Approach from the north to observe the starboard side hull profile; diving allows 360-degree inspection of wreck structure.
Wide-angle underwater photography captures hull silhouette; morning light penetration is best; macro shots of coral growth on hull surfaces.
North hull side in morning light; coral colonies on deck; fish school behavior through open hull sections.
Reef fish (grouper, snapper, angelfish), sea turtles, moray eels, rays, corals, lobster.
Strong afternoon winds, summer thunderstorms (May–September), rough Atlantic swells (December–March), occasional cold fronts with water temperature drops.
Fowey Rocks Lighthouse, Alicia shipwreck, Arratoon Apcar wreck, Erl King wreck, Mandalay wreck, 19th Century Wooden Sailing Vessel.
Fuel, supplies, and restaurants in Key Largo (north) and Key West (south); bait and tackle shops at Convoy Point and Islamorada.
Boat launch via paved ramp at Convoy Point. Access requires private vessel or commercial tour operator. Close examination requires diving equipment and certification. Snorkeling possible from surface for strong swimmers.
Viewing from boat deck suitable for all ages. Snorkeling requires strong swimming ability and adult supervision for children. Diving not recommended for children under 12. Boat ride can be rough in choppy sea conditions—use seasickness medication if prone.
Parking, picnic areas, and restrooms at Convoy Point launch facility. Visitor center with interpretive exhibits 3 miles north at Key Biscayne entrance. Boca Chita Campground and Elliott Key Campground available for overnight trips.
To Park Entrance
Approximately 7 nautical miles from Convoy Point boat launch.
" Visitors appreciate the authentic maritime archaeology experience and accessible wreck viewing for snorkelers and divers. Most understand the historical significance; some express surprise at the visible deterioration since earlier decades. Feedback emphasizes the importance of checking sea conditions and boating experience before attempting the trip."
Yes, with proper diving certification and experience. Depths reach 25 feet, requiring attention to nitrogen narcosis and decompression safety. Most tour operators require Advanced Open Water certification. Independent divers must be comfortable with strong currents and limited visibility.
Partially. The broken mast and upper hull sections are sometimes visible at low tide and clear water conditions, but most of the structure remains below the surface. Snorkeling or diving offers the full archaeological experience.
Yes, but prepare for afternoon thunderstorms and strong winds. Water temperature is warmest (80–85°F), offering the best visibility and comfort. Launch early to complete the trip before afternoon weather deteriorates.
Both options exist. Private boat launch at Convoy Point costs only parking fees. Commercial tour operators offer guided trips with equipment rental; these are recommended for first-time visitors unfamiliar with reef navigation.
Grounded March 9, 1913, in heavy seas on its way to Havana. Despite aggressive salvage efforts recovering $150,000 in cargo, the hull proved impossible to refloat. It was declared a total loss and abandoned on April 15, 1913. The broken wreck remains protected as maritime heritage.
The hull sits approximately 25 feet below the surface on Long Reef. Depth varies slightly with tide and swell; divers should check current conditions with a tour operator or the park before attempting the dive.
Yes. Currents around the reef are strong, visibility can be limited by weather or tidal timing, and nitrogen narcosis affects divers below 30 feet. Maintain 100-yard distance from sea turtles. Never touch coral or remove artifacts—it's a protected archaeological site.
