Crandon Park Beach
Crandon's two-mile beach on Key Biscayne sits behind an offshore sandbar that knocks down most of the surf, so the water inside is usually calm and shallow. Many swimmers head out to the bar and swim or wade along it. The bar shifts with storms, flotation devices aren't allowed, and parking is $7 plus tax Monday to Thursday, $10 Friday to Sunday.
Bill Baggs Cape Florida State Park
At the southern tip of Key Biscayne, Bill Baggs has a mile and a quarter of natural Atlantic beach open to swimming, with the 1825 Cape Florida Lighthouse at its end. There are no lifeguards, so swim with a partner and know your limits. The park opens at 8 a.m. and closes to all entry once it fills on busy weekends, so arrive early.
