Lignumvitae Key Botanical State Park

Located just offshore from Islamorada in the Upper Florida Keys, Lignumvitae Key Botanical State Park protects a secluded island known for its tropical hardwood hammock, cultural history, and peaceful setting. Named for the lignum vitae tree, the park preserves one of the region’s most notable remaining examples of native island habitat. Accessible only by boat, Lignumvitae Key is a rewarding stop for paddlers, boaters, birders, and visitors looking to experience a quieter side of the Florida Keys.

Things to Do at Lignumvitae Key Botanical State Park

See the Historic Matheson House
The island’s best-known historic feature is the Matheson House, built in 1919 by William J. Matheson:
- Learn about the island’s history as a private home and self-sustaining island retreat.
- Interpretive displays and ranger- or volunteer-led programs may highlight the house, the family’s legacy, and the island’s ecology.
- Tour availability can vary by season, staffing, and weather, so it is smart to check ahead.
Walk the Nature Trails
Short natural trails lead visitors through one of the best-preserved tropical hardwood hammocks in the Keys:
- Look for native plants such as lignum vitae, mahogany, gumbo limbo, and wild tamarind.
- Interpretive signs help explain the ecological importance of this rare island habitat.
- Bring binoculars for birds, butterflies, and other small wildlife that may be active along the trail.
Paddle or Boat to the Island
Getting there is part of the experience:
- Arrive by kayak, canoe, paddleboard, or private boat when conditions allow.
- The crossing from nearby Islamorada can be scenic but weather, wind, and tides matter, especially for paddlers.
- Local outfitters and eco-tour operators may offer guided trips or rentals nearby.
Enjoy a Quiet Picnic
Lignumvitae Key is more about atmosphere than crowds:
- Limited picnic seating may be available in shaded areas.
- Bring your own water and snacks, since concessions are not available on the island.
Wildlife and Water Views
The park sits within the broader Florida Bay and Florida Keys marine environment:
- Watch for wading birds, shorebirds, fish, rays, and other coastal wildlife from the shoreline or your boat.
- If you explore nearby waters, use care around seagrass beds and follow all marine sanctuary and boating regulations.

Unique Features of Lignumvitae Key

Rare Tropical Hardwood Hammock
Lignumvitae Key protects one of the Florida Keys’ most significant remaining tropical hardwood hammock communities.
- This habitat supports native tree species and understory plants that were once far more common across the island chain.
Historic Matheson House
The preserved 1919 home adds cultural history to the island’s natural appeal and helps tell the story of early life in the Keys.
