Welcome to Dagny Johnson Key Largo Hammock Botanical State Park

Once slated to become a condominium development, this park contains one of the largest tracts of West Indian tropical hardwood hammock in the United States.


The park is home to 84 protected species of plants and animals, including wild cotton, mahogany mistletoe and the American crocodile.

Exploring the park's trails gives visitors a chance to see some of these rare species of plants and animals. Over six miles of nature trails provide a wealth of opportunities for birdwatchers and photographers. Most of the park's trails are paved and accessible to both bicycles and wheelchairs.

Signs along a self-guided nature trail provide information about the park's ecosystem and wildlife. Ranger-guided tours are also available.

This park is located on County Road 905, half-mile north of the intersection with U.S. Highway 1 at Mile Marker 106.
