Islamorada is known for its off-the-beaten-track attractions, but the sights at Windley Key Fossil Reef State Park are sure to be some of your favorites. This park is located at Mile Marker 85.5 near Islamorada.
The park is a former 1900s quarry that was used by Henry Flagler, an oil and railroad tycoon known as the founder of the Florida East Coast Railway. Before the grounds were used as keystone and railway construction quarries, travelers to the area wouldn’t have seen any “land” at all — the entire area is a fossilized coral reef! As you explore, take note of the sea-like patterns in the rocks and the evidence of underwater life on the vast number of walking trails. Admission into the park is only $2.50 per person, along with another $2 for a guided tour of the park. Please note that the park is closed to visitors on Tuesdays and Wednesdays.
