Often dubbed the capital of sport fishing, and scuba diving, the Florida Keys is an epicenter for exploring marine wildlife, think coral reefs teeming with vibrant aquatic animals, but there is a unique place where nature aesthetes can find a freshwater sanctuary filled with animals. Right in the middle of Big Pine Key (which is one of the largest islands in the lower Florida Keys) lies an abandoned rock quarry known as the Blue Hole. The Blue Hole is a freshwater lake sourced from frequent rains and salt water that filters in through a limestone unlike the Great Blue Hole in Belize, which was formed when rising seawater flooded a series of gigantic caverns at the end of the last Ice Age.

Thanks to the great work of the visionary Henry Flagler who not only built a railroad in the area to facilitate mobility but has also created a supply of fresh water for the endangered animal species such as the Key Deer, which is the only deer species that live on Big Pine Key. The Blue Hole forms an integral part of the Florida Keys National Wildlife Refuge ensuring the survival of other wildlife such as the large iguanas, birds, fishes, and of course the Florida Alligator. Nature lovers prefer to explore this sanctuary by taking a short hiking trip. The 0.7 miles out-and-back hiking trail is an easy route to complete with children. This can be a wonderful way to get up close and personal with the wildlife.
