Miami has some magnificent parks. And little known to most citizens, the parks and rec department showcases their amazing assets via an Eco-Adventures program. For reasonable fees, they offer some awesome options, including Redland bike tours, snorkeling at Crandon Park, moonlight kayaking in Key Biscayne, Everglades camping and swamp field trips to Fakahatchee Strand State Preserve. Besides, what good is living in a tropical paradise if you don't get out and enjoy it?
