San Pedro Underwater Archaeological Preserve State Park

San Pedro Underwater Archaeological Preserve State Park is a Florida State Park located in 18 feet (5.5 m) of water, approximately 1.25 nautical miles (2.32 km) south of Indian Key. It became the second Florida Underwater Archaeological Preserve when it opened to the public in 1989. The heart of the park is the San Pedro, a submerged shipwreck from a 1733 Spanish flotilla, around which visitors can dive and snorkel.

The San Pedro, a 287-ton Dutch-built vessel, and 21 other Spanish ships under the command of Rodrigo de Torres left Havana, Cuba, on Friday, July 13, 1733, bound for Spain. The San Pedro carried a cargo of 16,000 silver Mexican pesos and crates of Chinese porcelain. A hurricane struck the fleet, while entering the Straits of Florida, and sank or swamped most of the fleet.

The wrecksite includes an "eighteenth century anchor, replica cannons, ballast stones encrusted with coral, a dedication plaque, and a mooring buoy system." The wreck was added to the U.S. National Register of Historic Places on May 31, 2001.

San Pedro Underwater Archaeological Preserve State Park occupies a particular place in the imagination of American public lands. As a State Park in Florida, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
