Dagny Johnson Key Largo Hammock Botanical State Park

Dagny Johnson Key Largo Hammock Botanical State Park is a natural reserve featuring tropical hardwood forest and over six miles of walking trails through thick vegetation. The landscape displays multiple ecosystems typical of this region of the Florida Keys.

The land was originally planned as a housing development before becoming a protected area in 1982. It was named after environmental activist Dagny Johnson, who worked to preserve this landscape.

The signs along the walking paths teach visitors about the local plants and animals that thrive in the tropical forest here. These markers help explain how this landscape connects to the broader ecosystem of the Florida Keys.

Access is through marked entrances, and the best visiting times are the cooler morning or late afternoon hours. Bring plenty of water and wear sturdy shoes, as the paths cross through wet vegetation areas.

The reserve provides refuge for animal species found only in this small part of the Florida Keys, such as the Key Largo woodrat. This isolation has created unique wildlife found nowhere else in the world.
