John D. MacArthur Beach State Park is one of Palm Beach County’s loveliest low-key coastal escapes: a protected barrier-island park in North Palm Beach where an Atlantic beach, mangrove estuary and the Lake Worth Lagoon all fit into one outing. It is a particularly good choice for travelers who want more than a chair-and-umbrella beach day, with a boardwalk walk, wildlife viewing and an attainable kayak trip to Munyon Island.
Beach access: what the walk is like
After entering at 10900 Jack Nicklaus Drive, park visitors follow the long boardwalk over the estuary and through tropical hammock habitat before reaching the sand. The boardwalk itself is part of the experience, especially at lower tide, when birds and marine life are easier to spot in the mangroves below. At its end, a sandy path through the dunes opens onto the Atlantic shoreline.
The park has roughly 1.6 miles of comparatively natural beach for swimming, shelling, strolling and settling in with a towel. Swimming is allowed when beach safety flags permit it, so take a look at conditions before carrying everything down. Three beach wheelchairs are available free on a first-come, first-served basis; ask staff when you arrive if one would make the beach day easier.
Parking, admission and hours
The park is open daily from 8 a.m. until sundown, including holidays. Current admission is $5 per vehicle for two to eight people, $4 for a single-occupant vehicle or motorcycle, and $2 for pedestrians, bicyclists and extra passengers. Parking is inside the park and entry is first come, first served, so an early start is the smart move on sunny weekends and holiday periods. Buying a Florida State Parks day pass in advance does not guarantee entry if a park has reached capacity.
There are some important facility updates to know before packing the cooler. The North Beach restroom remains closed until further notice. Restrooms in the Nature Center area are also currently unavailable, with portable toilets provided instead. Outdoor shower facilities, picnic areas, a playground and the Nature Center remain useful parts of a beach day, but check the park’s current alerts before leaving home in case conditions change.
Kayaking to Munyon Island
Munyon Island is the signature paddle here. The island sits in the lagoon west of the beach and can only be reached by boat. From the park’s kayak launch, paddlers can work through the sheltered estuary, pass beneath Burnt Bridge and continue toward the island. It is a calm-water adventure rather than an open-ocean crossing, but it still deserves real preparation: watch the forecast, respect tides and bring water.
The Beach Outfitters Gift Shop rents kayaks and stand-up paddleboards on a first-come, first-served basis. Current kayak pricing is $15 per hour for a single or $20 per hour for a double; half-day rentals cost $38 and $50, respectively, while full-day rentals cost $60 and $70. Rentals begin at 9 a.m.; the final rental goes out at 3 p.m., and all rental paddlers must be checked back in by 4 p.m. If winds are 15 mph or less, rentals may travel throughout the park waters, including toward Munyon Island. At 15 to 19 mph, rentals are limited to the estuary, and at 20 mph or above, rentals are suspended.
You may bring your own canoe or kayak and use the public launch; ask at the entrance gate for directions. High tide generally makes navigating the estuary easier, while low tide reveals mud flats and can make the route feel much shallower. A compact waterproof dry bag is worthwhile for phones, keys and a snack.
Once on Munyon Island, there are nature trails, covered picnic areas, grills and a day-use dock. There are no restrooms and no overnight use, so plan accordingly. The island dock can accommodate up to 20 boats, and boat traffic in the lagoon is another reason to stay alert while paddling.
Snorkeling: set expectations, then go prepared
Snorkeling and scuba diving are permitted off MacArthur Beach, and the park’s shallow nearshore reef habitat can make for a rewarding look when the ocean is calm and visibility cooperates. It is not a guaranteed clear-water snorkeling destination every day: surf, wind, tide and recent weather can change conditions quickly. The park notes that reaching the shallow reefs with full scuba gear involves a long carry across the beach, so snorkelers tend to have the simpler setup.
Florida requires snorkelers and divers to display a diver-down flag. The gift shop rents flags for $5 per day with a $20 deposit or a Friends membership card. Bring your own properly sized flag if you prefer, plus fins and a well-fitting anti-fog snorkel mask. Stay close to shore, keep an eye on the flags and never push through rough surf for a reef look.
Practical takeaway: Arrive close to opening, paddle around high tide if Munyon Island is on your list, and treat current wind, ocean flags and facility notices as the final word for the day.
