Snorkel with the fishies, spend a day on a boat, relax on the beach, or suit up for a scuba dive at Biscayne National Park. This park is the largest marine park in the National Park System and protects four ecosystems: a stretch of mangrove forest along the shoreline, the southern portion of Biscayne Bay, the northern Florida Keys, and a part of the world's third-longest living coral reef. All of these ecosystems mean that there's plenty of nature to explore here. There's also a visitor center on site with an art gallery featuring works inspired by the park and other attractions.
Visit the Kampong National Tropical Botanical Garden to see a variety of tropical plants from all around the world. The outdoor garden is full of plant life from Southeast Asia, Central and South America, and the Caribbean, and includes a number of fruit and flowering trees. A few plants you may see are the cultivars of candle fruit, peanut butter fruit, egg fruit, cocoplums, and over 50 varieties of mango.
Explore the mysterious structure that is the Coral Castle. This unique stone landmark was constructed by Edward Leedskalnin over a 28 year period, from 1923 to 1951. How one man built this solid stone “castle” is still a mystery – supernatural powers? Superhuman strength? Sheer determination? No one witnessed the building process and Ed refused to share his secret, saying only that he knew “the secret of the pyramids”. Once you tour the massive Coral Castle you'll be in awe, and a little mystified, by the brilliant creation of one man.
