Overview

A short, worthwhile sampler of the Upper Keys’ natural and human history, the Hammock Trail is a 0.6‑mile loop inside Windley Key Fossil Reef Geological State Park. It’s walking‑only and mostly shaded, weaving through tropical hardwoods and skirting former coral‑reef quarries. Expect uneven limestone underfoot rather than a flat, paved stroll.

What You’ll See

Interpretive signs help you pick out gumbo‑limbo, paradise tree, ironwood, thatch palms, and even cacti unique to the Keys. The loop passes the filled Russell Quarry and connects to short spurs toward the larger Flagler Quarry, where quarry walls reveal fossil coral that helped build Henry Flagler’s Overseas Railway. Watch for white‑crowned pigeons and occasional green parrots; iguanas are regular sun‑soakers along the rock.

Trail Notes

The route begins behind the Alison Fahrer Education Center—grab the free trail guide before you step onto the rock ledge. Bikes aren’t allowed, and the substrate is bright, sharp Key Largo limestone, so closed‑toe shoes beat flip‑flops every time. Stay on marked paths: poisonwood is common here, and its sap can cause a nasty rash. Mosquitoes can be persistent; golden digger wasps are sometimes around but are generally non‑aggressive if left alone.

Best Time to Hike

The park is open 8:00 a.m.–4:00 p.m., Thursday through Monday. Aim for the first hour after opening for cooler temps and quieter paths. Midday sun reflects off the pale reef rock—bring reef‑safe sunscreen, water, and a hat. This is a quick outing; if you want more, add the nearby short interpretive loops within the park for a 30–60 minute visit total.

Logistics

Entry is $2.50 per person. Restrooms, exhibits, and picnic tables are near the visitor center. Trails are rocky and can be slick when wet; watch your footing and keep children close around quarry edges. Collecting plants or fossils is prohibited. Pet policy isn’t specified in the available materials—call the park to confirm before bringing a dog.

Pros

  • Interpretive tree ID signs in a true tropical hardwood hammock
  • Easy link‑ups to quarry overlooks for up‑close fossil reef views

Cons

  • Limited hours (Thu–Mon, 8–4) restrict late‑day visits
  • Sharp, uneven limestone underfoot; flip‑flops are a bad idea
  • Poisonwood is common—stray off trail and you may regret it

Parking

Park at Windley Key Fossil Reef Geological State Park off the bayside of US‑1 (about 0.5 miles south of Mile Marker 85); the trailhead starts behind the Alison Fahrer Education Center.

Caution

Stay on marked paths to avoid poisonwood; wear closed‑toe shoes for sharp, uneven limestone; bring insect repellent and water; wasps may be present but are non‑aggressive unless provoked; no bicycles; do not collect plants or fossils.
