Natural Escape at Dagny Johnson Key Largo Hammock Botanical State Park

Dagny Johnson Key Largo Hammock Botanical State Park, located in Key Largo, Florida, offers a rare and peaceful glimpse into one of the largest remaining tracts of West Indian tropical hardwood hammock in the United States. This state park stands apart as a crucial preserve for an ecosystem that once stretched widely across the Florida Keys but is now highly threatened. Visitors here witness an uncommonly rich variety of plants, including the rare Florida semaphore cactus and wild cotton. The park’s extensive trails wind through dense hammock forest and coastal mangroves, providing habitat for endangered species like the Key Largo woodrat and various vibrant butterfly species.

This area presents a unique natural environment where the subtropical climate supports unusual wildlife and plant life not found elsewhere in the region. The presence of both paved and natural trails offers an inviting walk through shady woods and alongside tranquil waterways. The park also features a charming butterfly garden and picnic area, making it a pleasant spot for a quiet day outdoors.

Named for conservationist Dagny Johnson, whose efforts helped protect this land from development, the park carries an important history of environmental activism in Florida. Despite its beauty, visitors should be aware that sections of the trails can become muddy or flooded after rain, and mosquitos can be quite persistent. A small vault toilet near the entrance provides basic facilities, but the area maintains a rustic feel that helps preserve its ecological character. For those patient enough to navigate the subtle trail network, Dagny Johnson Park reveals a peaceful, natural retreat away from the typical Keys tourist spots.
