SOUTHWEST FLORIDA may be fringed by white-sand bays and dotted with tropical islands, but there’s way more here than postcard-perfect views. This is a region home to the largest undeveloped mangrove ecosystem in the country and more shell varieties than anywhere else in the US. It’s a habitat for bottlenose dolphins and sea turtles, wild cypress forests and more than 300 species of birds. Basically, it’s an insanely good-looking Pinterest board come to life. Here’s proof.
