Opened to the public in 1969, St. Lucie Inlet Preserve State Park preserves one of the few undeveloped barrier islands on Florida's east coast. The park is composed of 10 distinct natural communities including beach dune, coastal strand, maritime hammock and tidal swamp. An extensive Anastasia worm reef is located offshore and extends 4.7 miles along the coast. This reef is the northernmost limit for the ranges of several species of corals found in South Florida.
Accessible by private boat only, the beach area of the park is the focus of recreational activities at St. Lucie Inlet Preserve State Park. Activities include swimming, snorkeling, scuba diving, sunbathing, fishing, picnicking, hiking and nature appreciation. This barrier island became a state park in 1965.
An extensive Anastasia rock reef is located just offshore of the park extending 4.7 miles along the coast and up to one mile offshore. Depths range from 5 to 35 feet. This reef is the northernmost limit for the ranges of several species of corals found in South Florida. In addition, many species of marine plants and tropical fishes are associated with the reef.
The park's varied habitats provide excellent opportunities for birding enthusiasts to view many different species of birds. The park is part of the Great Florida Birding Trail. St. Lucie Inlet Preserve is a good place to see wading birds and shorebirds, such as great blue herons, brown pelicans, white ibis and the purple plover.
