Fodor's Review

The fossilized-coral reef, dating back about 125,000 years, demonstrates that the Florida Keys were once beneath the ocean. Excavation of Windley Key's limestone bed by the Florida East Coast Railway exposed the petrified reef, full of beautifully fossilized brain coral and sea ferns. Visitors can see the fossils along a 300-foot quarry wall when hiking the park's three trails. There are guided (Friday, Saturday, and Sunday only) and self-guided tours along the trails,

which lead to the railway's old quarrying equipment and cutting pits, where you can make rubbings of the quarry walls. The Alison Fahrer Environmental Education Center holds historic, biological, and geological displays about the area, including videos. The first Saturday in March is Windley Key Day, when the park sells native plants and hosts environmental exhibits.
