A quiet area on a barrier island, Sand Key is known for its namesake park, featuring a playground, picnic facilities, and a beach. Seashells dot the sand, making it popular for beachcombers, and kayak and bike rentals are available. The beach is a nesting site for endangered sea turtles, while a salt marsh draws herons and anhinga. Seafood restaurants and casual grills, many with bay views, line Gulf Boulevard.
