Partiers, families, and overnight campers all have a place to go on the 79 acres here. The island, in a wide section of the Intracoastal between Palm Beach Island and Singer Island with an open channel to the sea, is accessible only by private boat or water taxi, two of which set sail regularly from the Riviera Beach Municipal Marina (www.peanutislandwatertaxi.com) and the Sailfish Marina (www.sailfishmarina.com/water_taxi). Fun-loving seafarers looking for
an afternoon of Jimmy Buffett and brewskis pull up to the day docks or the huge sandbar on the north—float around in an inner tube, and it's spring break déjà vu. Walk along the 20-foot-wide paver-lined path encircling the island, and you'll hit a 170-foot fishing pier, a campground, the lifeguarded section to the south that is particularly popular with families because of its artificial reef, and last but not least, the Palm Beach Maritime Museum's "Kennedy Bunker" (a bomb shelter prepared for President John F. Kennedy that was restored and opened to the public in 1999). There are picnic tables and grills, but no concessions. A new ordinance means alcohol possession and consumption is restricted to permit areas. Amenities: lifeguards (summer only); toilets; showers. Best for: partiers; walking; swimming; sunrise.
