In these waters, snorkelers can explore vibrant coral formations and enjoy encounters with a myriad of sea creatures, including angelfish, parrotfish, barracuda, and even sea turtles.

The Christ of the Abyss, a submerged statue located in the Dry Rocks area, is a must-visit spot within the park.

It’s one of the best places in the Keys to see elkhorn and staghorn corals. Schools of colorful tropical fish, rays, and sharks are commonly seen here.
