Whether you're discovering Key Largo, which sprawls across more than 10 miles or just passing through on your way to one of the other Keys, a stop at Harry Harris Park, mile marker 93.5 oceanside, makes for a pleasant visit. At this waterfront park, you can walk the beach, give the children a break in the toddler playground, join a game at the sports field or enjoy lunch on a covered picnic table for a lazy afternoon of sun, sand, wine, cheese and watersports. Entry is free Mondays through Fridays. On weekends, children age 12 and under are free.
