John D MacArthur Beach State Park

Top choice state park in Treasure Coast

While this state park is one of the smallest in the region (438 acres), it has some of the best turtle-watching programs around. Loggerhead, green and leatherback turtles nest along the beach between May and August. It's home to aquariums and a spectacular 1600ft boardwalk spanning the mangroves of Lake Worth Cove. The on-site nature center offers kayak rental (unguided; single kayak $12 per hour).

In June and July, lucky visitors might catch a glimpse of hatching baby sea turtles during the ranger-led turtle walks, led nightly at 8:30pm.
