Windley Key Fossil Reef Geological State Park is a Florida State Park located at mile marker 85.5 near Islamorada. It was a former quarry used by Henry Flagler in the early 1900s to help his building of the Overseas Railroad. Following the railroad's completion, it was a source for decorative stone pieces called Keystone. Now on display are exposed sections of fossilized coral, as well as some of the original quarry machinery. The Hurricane Monument at Mile Marker 82 in Islamorada is constructed of keystone from the quarry.

  • We spent sometime here exploring and hiking around during our Christmas vacation to Islamorada in Dec 2020. Kids loved the big rocks and had fun hiking the short trails and taking fun photos. Neat.....  more »
  • Cool things to see like the large corals in the quarry wall and the trees and plants along the winding hiking trails through the hammock. This is a must-see for the kids and geology types.  more »
  • This is quite possibly the best self-guided tour I've ever been on, and that's saying something. It's a fascinating place to visit, and I recommend visiting all of the trails. Definitely worth your time, especially for $2.50 a person.
  • Great place for a hike and affordable at $2.00-$3.00 a person. There are at least six different trails through the Hammock forest and a great place to take your dog on a walk. They also give a plant and trail guide free to use when you pay admission. Highly recommended for a relaxing walk in nature and to learn about the quarry’s history.
