When visiting the Florida Keys it is hard to miss the Florida Keys National Marine Sanctuary as most of the water surrounding the Florida Keys is part of the sanctuary. Covering 2,900 square nautical miles, the Florida Keys National Marine Sanctuary protects the incredible underwater world of the Florida Keys, where reefs and animals flourish.

During a visit to the Florida Keys National Marine Sanctuary, you have a few different options for how to experience this protected area of nature. The sanctuary is home to the world’s third largest barrier reef and is an excellent spot for scuba diving or snorkeling. There are even a series of shipwrecks you can explore as a diver called Shipwreck Trail.

If you’d rather stay above water, you can rent a boat to explore the sanctuary and possibly do some fishing. When boating it is important to use mooring buoys for your anchor as they won’t damage the reef. In addition, boaters should pay attention to the commands of other buoys in the sanctuary as they are strategically placed to protect the environment.

To learn more about the history and conservation efforts of the Florida Keys National Marine Sanctuary, a visit to the Florida Keys Eco-Discovery Center is a must. Through interactive exhibits you’ll learn about the land-based and under the sea wildlife and plants of the Florida Keys. There is also a living reef tank, which has an abundance of coral and fish living in it.

Whether you are 30 feet or a 100 feet underwater, Amoray Diving experience is one of a kind! The ocean is brisk, the slight current is stirring the sand, the colorful fish are swarming, the bright red lobsters are playfully harassing the neon eels — everything seems surreal, especially the fact that you’re breathing underwater. If you can love big, be open and trust in the power of good, the world truly is an oyster that is waiting to be explored. For most people, this is as close to being an astronaut as you’ll ever get. It’s leaving planet Earth behind and entering an alien world.
