Sandfly Hiking Trail

A wooden boardwalk through a dense forest of mangrove trees

Sandfly Island offers a short, flat 0.9-mile walk through layers of Florida's human history. The Calusa Indians engineered this horseshoe island for tidal fishing, and pioneer homesteaders left behind a concrete cistern you can still see. The trail reveals how nature and human design shaped this mangrove estuary, all in 40 minutes with historical interpretation and scenic views.

Safety & strategy

Best Time To Visit: Visit October through April when humidity drops and mosquitoes thin out. Start by 7am to beat the midday heat and afternoon crowds.
Tips Advice: Carry 2L water minimum—the bare ground offers no shade relief
Apply insect repellent before you go; mosquitoes are relentless May-October
Wear light-colored, long sleeves for sun and bug protection
Tighten your boots—the ground is uneven and can twist ankles
Bring a light layer; wind can pick up near the water
