Even better than the Seaquarium is Sea Grass Adventures, in which a naturalist from the Marjory Stoneman Douglas Biscayne Nature Center will introduce kids and adults to an amazing variety of creatures that live in the sea grass beds of the Bear Cut Nature Preserve near Crandon Beach on Key Biscayne. Not just a walking tour, you will be able to wade in the water with your guide and catch an assortment of sea life in nets provided by the guides. At the end of the program, participants gather on the beach while the guide explains what everyone's just caught, passing the creatures around in miniature viewing tanks.
