Welcome to Lignumvitae Key Botanical State Park

The virgin tropical hardwood hammock that thrives on this island was once common on most of Florida's Upper Keys.

Pay Online, Single-Use Day Pass

In 1919, William J. Matheson, a wealthy Miami chemist, bought this tiny island and built a caretaker's home with a windmill for electricity and a cistern for rainwater. Today, his hideaway is the visitor center for this island forest.

Ranger-guided tours are currently unavailable. However, there is a self-guided tour brochure that visitors can use to learn about the home and other features that dot the lawn.

Lignumvitae Key is accessible by boat or kayak only. Boat and kayak rentals are available through local vendors.

Seagrass Ecosystem of Lignumvitae Key

Have you ever heard the saying "Brown, brown, run aground”? Shallow water in the nearshore environments of the Florida Keys can look brown due to light reflecting off a substrate of seagrass. While the seagrass flats may not look like much to the casual observer, seagrass is vital to the Florida Keys ecosystem.
