Windley Key Fossil Reef Geological State Park

Located in Islamorada in the Florida Keys, Windley Key Fossil Reef Geological State Park is a compact but memorable park that highlights the region’s geology and railroad-era history. The site preserves a former quarry where fossil-rich Key Largo Limestone was cut for use during the construction of Henry Flagler’s Overseas Railroad and other local projects. Today, visitors can walk short interpretive trails, view exposed quarry walls, and explore exhibits that explain how ancient coral reefs helped shape the Keys. It is a rewarding stop for travelers interested in nature, history, photography, and easy sightseeing.
