Picnic Key is near the Northwest corner of the park, literally next door to Tiger Key. A narrow channel separates the two islands. (Tiger Key's camping areas are on the opposite side from Picnic Key.)
icnic Key is a beach site. There's room for several groups, with a porta john at the West end of the beach. Because of easy boater access to this porta john, there's a fair number of people stopping to use it, so you might want to camp at the other end of the beach. Signs advising "Nudist in the area" or something similar would be a good idea.
