St. Lucie Inlet Preserve State Park is a Florida State Park east of Port Salerno on the northern end of Jupiter Island and is accessible only by boat. Activities include snorkeling and scuba diving, swimming, sunbathing, fishing, and picnicking and wildlife viewing.
Among the wildlife of the park are migratory birds such as the Peregrine falcon, Broad-winged hawk and the American kestrel, as well as bobcats, otters, raccoons. Amenities include more than 2 miles (3.2 km) of sandy beach, a 3,000-foot (910 m) boardwalk, and 8 picnic tables.
A boardwalk takes visitors across mangrove forests and hammocks of live oaks, cabbage palms, paradise trees, and wild limes to a neatly preserved Atlantic beach. During the summer months, the island is an important nesting area for loggerhead, leatherback and green turtles. They come ashore at night to dig holes in the beach sand where they lay their eggs.
The preserve is a favorite for nature students interested in learning about the native flora and fauna of Florida barrier islands.
Visitors come to swim, sunbathe or picnic at the pavilion on the quiet beach. Others make the trip for the great surf fishing. Snorkeling and scuba diving are also popular activities.
