Dagny Johnson Key Largo Hammock Botanical State Park

Dagny Johnson Key Largo Hammock Botanical State Park protects one of the largest remaining stands of tropical hardwood hammock in the Florida Keys. Named after a pioneering conservationist, this 2,400-acre park preserves a rare and fragile ecosystem that once covered much of the Keys before development. The park offers visitors a chance to experience the unique plant communities and natural character that define the island chain.

The park's primary attraction is its network of hiking trails that wind through dense tropical hardwood forest. Visitors can explore the hammock's diverse vegetation, including native trees such as gumbo-limbo, mahogany, and poisonwood, along with tropical understory plants and vines. The trails provide a cool, shaded respite from the Florida Keys heat and offer glimpses into the ecological richness that supports the region's wildlife.

This state park is ideal for nature lovers, hikers, and photographers seeking an authentic Keys experience away from commercial attractions. The preserve's peaceful setting and botanical diversity make it an excellent destination for learning about Keys ecology and appreciating the importance of habitat conservation. Whether you're interested in a leisurely walk or a longer hiking adventure, the park offers accessible ways to connect with Florida's tropical natural heritage.

The hammock supports a diverse array of native Florida Keys wildlife, including tropical bird species, native tree snails, and various reptiles adapted to the hardwood forest environment. The dense canopy and understory vegetation provide critical habitat for species found nowhere else in Florida. Visitors may encounter wildlife typical of mature tropical hardwood ecosystems, making the park valuable for wildlife observation and ecological study.

• Visit during cooler months (November through April) to avoid intense heat and humidity while hiking. • Bring plenty of water, insect repellent, and sun protection—the trails offer limited shade in some areas. • Wear sturdy, closed-toe hiking shoes suitable for potentially uneven forest terrain. • Arrive early, especially on weekends, for better parking availability and a quieter experience. • Check current trail conditions before your visit, as paths may be affected by weather or maintenance.
