Windley Key Fossil Reef Geological State Park, Islamorada

Living in the Keys, it’s easy to get caught up in the beauty of the ocean and overlook the wonders that lie just inland. Windley Key Fossil Reef Geological State Park is one of those hidden gems that reminds us how layered and fascinating our home truly is. This park sits on land that was once actively quarried for the limestone used in Henry Flagler’s ambitious Overseas Railroad project in the early 1900s. What remains today is a striking display of fossilized coral reef — a geological time capsule frozen in stone.

Walking the trails, you’re surrounded by walls of ancient coral, remnants of a prehistoric seabed that give you a whole new appreciation for the natural history beneath our feet. The visitor center offers educational exhibits on both the railroad and the fossil reef ecosystem, making it a place where history and science meet. It’s a peaceful spot to reflect, recharge, and reconnect with the land—especially for locals who don’t always take the time to explore what’s in their own backyard. Whether you’re a nature lover, a history buff, or just looking for a quiet afternoon walk, this park offers something enriching and grounding.
