From an Olympic-sized pool to kayaking tours and the occasional open-water event on Biscayne Bay, Florida International University's waterfront campus offers several outdoor attractions to its sun-kissed student body. But it's the nature trail that best shows off the university's tropical setting. Beginning at the Glenn Hubert Library, wrapping around the campus, and running partly alongside Biscayne Bay, this three-mile trek is a master class in plant and wildlife native to Florida. Not only are birds such as the belted kingfisher and roseate spoonbill often visible from the trail, but also the damp surroundings attract Instagram-worthy butterfly species such as monarchs and sulphurs. Check out the mangroves, which not only serve as a barrier from the whipping sea breeze but also make for a prime nesting place for some of these incredible creatures. You won't need to worry about cutting class to take a stroll down the trail: It's open to the non-Panther public.
