For your next family adventure, push pause on the sunbathing and head over to the eco-maniac’s dream come true that is Key Biscayne’s Marjory Stoneman Douglas Biscayne Nature Center. Spend the afternoon communing with nature through hands-on exploration programs. Your kids will love getting touchy-feely with the collections of shells and bones, or checking out sea creatures up close in the saltwater aquariums. Bring along your binoculars so you can point out some of the amazing winged wonders visible from the center’s bird observatory. Wade right into the seagrass and you’ll feel like a star as you introduce your kids to starfish, along with sea urchins and seahorses. Or take a tour through an ancient fossil reef that makes your hotel’s infinity pool seem positively finite. If your gang is the kind to dive in headfirst, hike up to the wreck of the Half Moon, a yacht cum underwater archaeological preserve that’s like a scene out of an animated Disney movie–minus the singing fish. You’ll also find boat trips and bike rides among the outings this $4 million center brings to the community. Opt for a beach walk with one of the well-informed naturalists and they’ll make sure your kids find the day as educational as it is fun.
