The Blue Hole is an abondoned rock quarry that was dug in the 1930s and 40s. The rock from the quarry was used to build local roads and Henry Flagler’s railroad. The Blue hole is a lake that has a fresh water surface that lays over the heavier salt water. It is home to some local wildlife including birds, turtles, a variety of fish and even a couple of American Alligators. It is a beautiful spot and the locals keep a close eye on it’s inhabitants.
