An extensive Anastasia rock reef is located just offshore of the park extending 4.7 miles along the coast and up to 1 mile offshore. Depths range from 5 ft. to 35 ft. 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. No spearfishing is permitted within state park boundaries.
