Seabranch Preserve State Park, State park in Martin County, Florida, United States
Seabranch Preserve State Park is a Florida State Park about ten miles south of Stuart, off A1A, in Martin County. It lies where the subtropical climate (Cfa) gives way to a tropical monsoon climate (Am), a boundary of note in phytogeography. Trails cross sand pine forest, scrubby flatwoods, baygall and mangrove swamp.
The area was shaped millions of years ago by ancient ocean waters that left behind varied soil types and elevated terrain. This geological foundation created the conditions for the diverse ecosystems visible in the park today.
The Tropical Trekkers, a chapter of the Florida Trail Association, maintain the hiking paths through this natural environment for public recreational access.
The park lies about ten miles south of Stuart, reached via A1A. It opens at 8 a.m. and closes at sundown every day of the year, holidays included, and charges no entrance fee. Trails run through sand pine scrub, flatwoods and mangrove swamps, so expect uneven ground and wet sections after rain.
The site marks a transition zone where subtropical plant species meet tropical species, with varying climate patterns influencing vegetation across the preserve. This boundary area supports a particular mix of species that visitors can observe while walking the trails.
