What You'll Find at MacArthur Beach

John D. MacArthur Beach State Park sits on Singer Island in North Palm Beach, about 45 minutes north of downtown West Palm Beach. The park spans 438 acres and includes a half-mile of Atlantic beachfront, a mangrove shoreline along Lake Worth Lagoon, and a shallow inlet system that connects the two. Most anglers fish the lagoon side rather than the open ocean beach—the lagoon holds permit, tarpon, snook, and redfish year-round, while the inlet and nearshore waters hold Spanish mackerel, pompano, and jack crevalle.

The park has a single boat ramp on the lagoon side, a small fishing pier, and beach access. There is no bait shop inside the park, so bring your own tackle or stop in North Palm Beach before you arrive. The park charges an entrance fee (currently around $6 per vehicle) and is open from 8 a.m. to sunset daily. Restrooms and a picnic area are available, but there is no fuel dock or fish-cleaning station.

Key Takeaways

  • The lagoon side holds permit, tarpon, and redfish in shallow water; the inlet and nearshore waters hold mackerel and pompano.
  • A single boat ramp serves the lagoon; the fishing pier is free to use once you pay park entry.
  • No bait or tackle is sold inside the park, so bring your own or stop at a nearby shop in North Palm Beach.
  • The park is open sunrise to sunset, and the best fishing windows are early morning and the last two hours before dark.

Fishing the Lagoon and Inlet

Lake Worth Lagoon is the main draw for most anglers. The water is shallow—typically 2 to 6 feet—and clear enough to sight-fish on calm mornings. Permit and tarpon move through the deeper channels and around the mangrove edges, especially during spring and early summer. Redfish and snook hold tight to the mangrove shoreline and in the shallow flats near the park's western boundary. The mangrove edges are particularly productive at dawn and dusk when larger fish move into the shallows to feed.

The inlet where the lagoon meets the ocean is a natural funnel for baitfish and larger predators. Spanish mackerel and jack crevalle patrol the inlet mouth during incoming tides, and pompano work the sandy bottom in 4 to 8 feet of water. If you fish from the pier, you can reach the inlet without a boat; the pier extends about 800 feet into the lagoon and is productive for snook and tarpon at dawn and dusk. The pier also gives you a vantage point to spot tailing redfish and permit in the shallows below.

Boat Ramp and Launch Details

The boat ramp is located on the lagoon side of the park, near the main parking area. It is a single-lane concrete ramp with limited parking—typically 10 to 15 spaces for boat trailers. During weekends and holidays, the lot fills early, often by 7 a.m. The ramp itself is in good condition and handles boats up to about 20 feet comfortably. Launch fees are included in your park entrance fee, with no separate ramp charge.

If the lot is full, you can park in the main lot and walk your gear to the ramp, though this is not ideal if you have a trailer. Arrive before sunrise if you want a may provide spot, especially on weekends. On busy mornings, other anglers launching and retrieving can create a wait of 15 to 30 minutes, so plan accordingly if you have limited time on the water.

Tides, Seasons, and Best Times to Fish

Lake Worth Lagoon is a tidal system, and the incoming tide pushes baitfish and larger fish into the shallows and mangrove edges. The best fishing windows are the last two hours of the incoming tide and the first hour of the outgoing tide. Slack tide—the brief period between tidal changes—is usually slow. Check tide tables before you go; the difference between a productive tide and a slow one can be several hours.

Spring (March through May) is peak season for tarpon and permit. Redfish and snook are present year-round but are most active in fall and winter when water temperatures drop. Summer can be productive early and late in the day, but midday heat and afternoon thunderstorms are common. Fall and winter offer the most consistent fishing and the most comfortable conditions for wading or poling the flats. Winter water temperatures can push fish deeper into channels, so focus on structure and tidal movement rather than the open flats.

What to Bring and What to Know

Bring your own tackle, bait, and water. The park has no concessions. If you plan to wade, wear polarized sunglasses and bring a headlamp for early morning—the flats are easier to read in good light. Mosquitoes are heavy in summer and after rain, so bring insect repellent year-round. A small cooler with ice is useful if you plan to keep fish or want cold water to drink.

The park has restrooms and a small picnic area but no fuel dock or fish-cleaning station. Cell service is spotty in some areas of the park. Parking is $6 per vehicle; if you have a Florida Parks Pass, entry is free. Dogs are allowed on the beach before 9 a.m. and after 4 p.m., but not on the fishing pier or in the water. Bring sunscreen and a hat—the sun reflects off the water and intensifies the heat, especially on the flats.

Nearby Resources and Tackle Shops

The closest tackle shops are in North Palm Beach, about 5 to 10 minutes from the park. These shops carry live bait, frozen mullet, and shrimp, plus local knowledge about current conditions. Stop before you enter the park if you need bait or last-minute tackle. Several shops also offer guide services if you want to fish with someone familiar with the lagoon system. Guides can show you where permit and tarpon hold and how to read the flats, which saves time if you're new to the area.

Gas stations and restaurants are scattered along US 1 in North Palm Beach and nearby Juno Beach. Plan to fuel up and grab food before or after your fishing trip, not during it. Most tackle shops open by 6 a.m. on weekends, so you can stop on your way to the park if you're launching at dawn.

Regulations and Licensing

Florida saltwater fishing requires a saltwater fishing license for anyone 16 and older. You can buy a 3-day, 7-day, or annual license online through the Florida Fish and Wildlife Conservation Commission (FWC) website or at most tackle shops. Bag limits and size restrictions vary by species—tarpon has a catch-and-release-only rule, while permit, snook, and redfish have specific slot limits that change seasonally. Check the FWC website or ask at a local shop before you fish to confirm current rules.

Snook and redfish seasons are closed during certain months to protect spawning populations, so verify the current season before you target these species. Permit have no bag limit but must be released in some areas during specific times. Keeping up with seasonal changes takes a few minutes online but prevents a costly mistake on the water.

Frequently Asked Questions

Can I fish the beach side of the park?

Yes, but most anglers fish the lagoon side because the water is calmer and shallower. The beach side faces the open Atlantic and is better for surfcasting for pompano and mackerel during rough conditions. The pier is the easiest way to reach deeper water without a boat.

Do I need a boat to fish here?

No. The fishing pier is free once you pay park entry and reaches productive water. You can also wade the lagoon flats from the beach access area, though a boat gives you access to more water and deeper channels where tarpon and permit hold.

What's the best time of day to fish?

Early morning (one hour before sunrise to two hours after) and the last two hours before sunset are most productive. Midday is usually slow. Fish the incoming tide if you can—it pushes baitfish into the shallows and triggers feeding.

Are there guides available?

Yes. Several guides operate out of North Palm Beach and fish the lagoon system regularly. Ask at a local tackle shop for recommendations. Guides can show you where permit and tarpon hold and how to read the flats, which saves time if you're new to the area.

What if the boat ramp is full?

Arrive earlier the next day—the lot typically clears by mid-morning on weekends. If you don't have a boat, the fishing pier is always open and doesn't require a ramp. You can also wade from the beach access area on the lagoon side.
