As climate change and resulting flooding reshape Miami's landscape, the city is becoming increasingly reminiscent of Venice. As the sea rises, you'll want to enjoy it as you would the Italian city: in a boat. Rent a kayak, canoe, or paddleboard at Alfresco Fun and head on a five-mile loop. Enter the Oleta River, paddle out to the bay, turn left (or to port, if you want to get nautical), and then beach at Duffy's. Buy yourself lunch or take advantage of the happy-hour specials. Then get back in your boat and paddle north. Turn left again and pass through Maule Lake before heading back to East Greynolds Park. Alfresco's rental prices dip as low as $12 for 45 minutes on a single kayak. The only mildly hairy spot on this route is passing under the 163rd Street Bridge, where big boats can make a wake.
