Fodor's Expert Review Windley Key Fossil Reef Geological State Park
The Florida Keys
Family
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. You can see the fossils along a 300-foot quarry wall when hiking the park's three trails.
