Lignumvitae Key Botanical State Park

Lignumvitae Key Botanical State Park protects one of the largest intact tropical hardwood hammocks in the Florida Keys. This undeveloped island, located off the coast of Islamorada, offers visitors a glimpse of the Keys as they existed centuries ago, with dense native vegetation dominated by lignum vitae trees—the park's namesake—along with mahogany, poisonwood, and gumbo-limbo species.

The park's centerpiece is the Mattheson House, a historic residence built in 1919 that sits among the island's lush tropical landscape. Visitors explore the island on guided tours that depart from the park's boat basin on Islamorada, where knowledgeable staff provide insight into the area's natural and cultural history. The 2.4-mile nature trail winds through the hardwood forest, offering an immersive experience of the Keys' unique tropical ecosystem.

Beyond the Mattheson House and trail system, the park preserves critical habitat for native species and showcases the botanical diversity that makes the Keys ecologically significant. The island's isolation and protection have allowed rare plants and wildlife to thrive in their natural state. This is an ideal destination for nature lovers, history enthusiasts, and anyone seeking a peaceful escape into old Florida.

Lignumvitae Key supports a diverse array of native wildlife adapted to the tropical hardwood hammock environment. Visitors may encounter native bird species, including roseate spoonbills, herons, and egrets, along with lizards and other reptiles. The surrounding waters and mangrove areas host fish, crustaceans, and marine species. The island's rich vegetation—particularly the rare lignum vitae tree—represents an irreplaceable example of the Keys' original natural heritage and provides essential habitat for threatened and endangered species.

• Access to the island is by guided tour only; reservations are strongly recommended, especially during peak season (winter months). • Tours depart from the park's boat basin on Islamorada; arrive early to secure parking. • Bring sun protection, including sunscreen and a hat, as the island offers limited shade. • Wear comfortable walking shoes suitable for a natural trail with uneven terrain. • Bring plenty of water, as there are no concessions or services on the island.
