This curious Miami landmark of colorful, crumbling buildings was originally built in the 1920s and '30s in the shallows on the northern end of Biscayne National Park. Available as a two-hour, government-sanctioned sightseeing cruise departing from Dinner Key Marina in Miami’s Coconut Grove, you'll be treated to stunning views and authentic stories about the area’s history and culture. You might even spot a few dolphins while you’re out there.
