It's hard to preserve waterfront property in Miami. If high-rise developers aren't locked in a bloody battle over a parcel, it's destined to become a gaudy mansion. Every now and again, a municipality gets a sliver of land to maintain for the masses. Alice C. Wainwright Park is a gem hidden among multimillion-dollar mansions on a hard-to-find spot south of downtown. To the north are Brickell's glittering office and condo towers. To the south is still-Bohemian Coconut Grove. The park is a narrow strip of green space that ends at Biscayne Bay and offers sweeping views of Key Biscayne and the edge of downtown Miami. The best place to roll out the blanket, before depositing the cheese and wine, is next to the water, which is separated from the rest of the park by a short, rocky drop-off. If you want to take things to the next level, fire up the built-in charcoal grills.
