Known to locals as "Mad Beach," this lively barrier island town occupies the southern tip of Shell Key. The beachfront consists of a long stretch of soft, shell-strewn sand, and it's often crowded with families as well as clusters of twentysomething beachgoers. You can get to the beach via numerous public access points, but your best bet is to park at the municipal beach parking lot and head to the sand from there. It's easily accessible from Treasure Island, northern
St. Petersburg, and Clearwater Beach. Amenities: food and drink; parking; showers; toilets. Best for: partiers; swimming; walking.
