Probably the largest cluster of beach access points is along A1A between Jupiter’s Carlin Park and the Juno Beach Pier. The paths swoop to the shore through hedges of sea grapes and gnarly trees. Two favorites are along the dog-friendly beach just south of the Jupiter Reef Club. No. 48, a little farther south, features a long, cool switchback boardwalk to the beach. Exploring the accesses is a fun way to exercise and break up an A1A stroll. A major plus is plenty of free parking along the road, or in nearby lots.
