Crocodile Lake National Wildlife Refuge

Crocodile Lake National Wildlife Refuge is a protected area in Key Largo that contains tropical hardwood forests, mangrove wetlands, and salt marshes. These different habitats create distinct zones where water and land meet, each supporting different wildlife populations across the refuge.

The refuge was established in 1980 by the United States Fish and Wildlife Service to protect American crocodile populations and their habitat. This protection measure came after the species had become severely threatened in the region.

The Community Butterfly Garden showcases local butterfly species and allows visitors to see how these insects live among native plants. Walking through the garden, you notice how the landscape is designed to attract and support the butterfly population that depends on these habitats.

The visitor center on US 1 Overseas Highway at mile marker 106 provides information and helps arrange visits to the refuge. Contact the center beforehand to learn about conditions, access routes, and the best times to see wildlife in the different habitats.

The refuge holds one of only three remaining breeding populations of American crocodiles in the southeastern United States. This critically small population makes the refuge a place of international importance for the survival of the species.
