Everglades National Park is situated in the Everglades in southwest Florida just 45 minutes from downtown Miami. This UNESCO World Heritage Site is Florida’s most famous park. Some describe it as a river of water and grass, others as a unique swath of often unfriendly terrain and cypress trees. Either way, it’s a significant part of a decidedly distinct ecosystem and is known as the home of the American crocodile. Visit during this US park’s dry season, November through April, when you have the best opportunity to spot the wild residents.
If you’re a caver visiting Kentucky, Mammoth Cave National Park is the place to be. It features the world’s longest-explored cave system. Every year many troglophiles travel select sections of the 400 miles of this cave system, delving deep underground into a mysterious maze of oft’times incredible sights.
Arguably one of the most memorable sections in the cave is known as Frozen Niagara. Tours to fit anyone’s spelunking expertise are available but you should book them in advance. If you want to avoid the crowds, the best time to visit is actually in the winter. For although the weather outside may be colder, the temperature inside the cave remains constant all year.
