Palm Beach County Parks Professional Review and Guide
"John Prince is a 726-acre urban park, but is nevertheless peaceful and shaded. This site on the Lake Osborne chain is great for as long as you can stay, because it is close to attractions and beaches, and if you have never strolled down Worth Avenue in Palm Beach on a warm summer evening, you must visit. With a watercraft and fishing license, this is a place to indulge.
A boat ramp is located in the campground. Prince also has a 5-mile multiuse path, a 0.5-mile wheelchair trail, 1.4-mile fitness trail, lighted tennis courts, playgrounds, rental picnic pavilions, and nature trail. Reservations are suggested."
