What Peanut Island Offers Anglers

Peanut Island sits in Lake Worth Lagoon just north of the Lake Worth Inlet, a 44-acre mangrove-ringed park that holds some of the most consistent shallow-water fishing in Palm Beach County. The island itself is small and heavily protected—you cannot fish from the island—but the surrounding flats and channels hold redfish, snook, tarpon, and permit year-round. The real fishing happens in the water around it: the shallow grass beds to the north and west, the deeper channel along the eastern shore, and the inlet mouth where tidal movement concentrates baitfish and larger species.

The lagoon here averages 4 to 6 feet deep on the flats, dropping to 8 to 12 feet in the main channel. Mangrove shorelines provide structure and shade, and the tidal exchange through the inlet keeps water quality high and baitfish abundant. This is sight-fishing water in the morning and evening, and blind-casting water when the sun is high. The island itself functions as a landmark and a current break—fish stack up on both sides depending on tide direction.

Key Takeaways

  • Fish the flats and channels around Peanut Island, not the island itself, which is a protected park where fishing is prohibited.
  • Redfish and snook are most reliable on the shallow grass beds during incoming tide, especially in early morning and late afternoon.
  • Access requires a boat; the nearest public ramp is at the Lantana Bridge or Riviera Beach Marina, both about 10 to 15 minutes away by water.
  • Tarpon move through the inlet mouth during spring and early summer, and permit work the deeper flats on the eastern side year-round.
  • Tidal movement is critical—fish the slack water at tide changes and the moving water along channel edges during peak flow.

Best Times and Tides for Peanut Island

Incoming tide is the most productive period around Peanut Island. Redfish and snook move shallow to feed as water rises, pushing baitfish into the grass beds and against the mangrove edges. The first two hours of an incoming tide, especially in the early morning, is when sight-fishing is most reliable. The water clarity improves as tide comes in, and fish are more aggressive.

Outgoing tide concentrates fish in the deeper channels and along the inlet mouth. Tarpon and large snook hold in the channel during the outgoing push, and permit often work the deeper flats on the eastern side of the island. Slack water—the 20 to 30 minutes between tide changes—can be slow, but it is when fish move between shallow and deep water, so it is worth fishing the transition zones.

Spring tide (the largest tidal swings) brings more water movement and more aggressive feeding. Neap tide (the smallest swings) can be slow, but the reduced current makes sight-fishing easier and keeps fish in shallower water longer. Check the tide tables for Lake Worth Inlet specifically; the timing varies slightly from the open ocean.

Species and What to Target

Redfish are the most consistent catch around Peanut Island. They hunt the shallow grass beds and mangrove edges year-round, feeding on mullet, shrimp, and small crabs. Early morning and late afternoon are best; fish the incoming tide on the western flats and the channel edges on the outgoing tide. Sight-cast to tailing fish in 2 to 4 feet of water, or blind-cast along the mangrove line with topwater plugs and soft plastics.

Snook are present year-round but most active from April through October. They hold tight to mangrove roots and channel structure, especially during the outgoing tide when current brings food to them. Fish live shrimp or mullet under the mangroves, or cast soft plastics and topwater near the deeper channel. The inlet mouth and the eastern channel are prime snook water during the outgoing push.

Tarpon move through the inlet mouth from April through June, following the spring baitfish migration. Fish the deeper water near the inlet during the incoming tide, when tarpon move into the lagoon to feed. Live mullet or mackerel work best; cast near the channel edges and let the current carry your bait into the tarpon's path. This is sight-fishing at its most demanding—tarpon are spooky and require a long cast and a quiet approach.

Permit work the deeper flats on the eastern side of the island year-round, though they are most abundant in spring and fall. They feed on crabs and small shrimp in 4 to 8 feet of water. Sight-cast small crab patterns or shrimp flies; permit are selective and require a precise presentation. Early morning and late afternoon are best, and the incoming tide concentrates them on the shallower flats.

How to Reach Peanut Island by Boat

Peanut Island is accessible only by boat. The nearest public boat ramps are at Lantana Bridge (on the Intracoastal Waterway, about 2 miles south) and Riviera Beach Marina (about 3 miles north). From either ramp, run north or south along the Intracoastal, then enter Lake Worth Lagoon through one of the marked channels. The island is clearly marked on GPS and visible from the water—it is a small, heavily vegetated island with a distinctive shape.

The run from Lantana Bridge to Peanut Island takes about 15 minutes in a center-console or flats boat. The Intracoastal is well-marked and relatively deep, but watch for commercial traffic and stay in the marked channel. Once you enter the lagoon, depths drop to 4 to 6 feet, so a shallow-draft boat (18 feet or less) is ideal. Larger boats can fish the deeper channel on the eastern side of the island, but the best redfish and snook water requires a boat that draws less than 2 feet.

Parking is available at both ramps, though Lantana Bridge fills quickly on weekends. Riviera Beach Marina charges a launch fee (typically $10 to $15) and has fuel and tackle shops nearby. Neither ramp has a dedicated fishing guide service, but several independent guides work the lagoon and can be found through local tackle shops or online guides directories.

Tackle and Bait for Peanut Island Flats

Light to medium spinning tackle is standard for Peanut Island. A 7 to 8-foot rod with 15 to 20-pound braided line handles redfish and snook in the shallow water, and the thin diameter of braid improves casting distance and bite detection. For tarpon and permit, step up to 20 to 30-pound braid and a longer rod (8 to 9 feet) to improve casting distance and hook-setting power.

Live bait is most effective: mullet (6 to 8 inches) for snook and tarpon, live shrimp for redfish and permit. Dead mullet works for snook and redfish when live bait is not available. Artificial lures are productive too—soft plastics (4 to 6 inches) in natural colors, topwater plugs for redfish and snook in shallow water, and small crab patterns or shrimp flies for permit. Tarpon respond to large topwater plugs and live mackerel.

Bring a push pole or electric motor for silent approach—noise spooks fish in shallow water. Polarized sunglasses are essential for sight-fishing; the morning sun angle (fishing east-facing flats) gives the best visibility. A landing net makes handling redfish and snook easier, especially if you plan to release them.

Rules and Restrictions at Peanut Island

Peanut Island itself is a protected park managed by Palm Beach County. Fishing from the island is prohibited, and landing on the island requires a permit. All fishing must occur in the water surrounding the island. Florida saltwater fishing regulations apply: redfish have a slot limit (18 to 27 inches), snook require a special permit and have seasonal closures (June 1 to August 31), and tarpon are catch-and-release only. Permit have no bag limit but are protected by state regulations on handling and release.

Check current regulations with the Florida Fish and Wildlife Conservation Commission (FWC) before you fish. Regulations change annually, and some species have seasonal closures or slot limits that vary by region. A saltwater fishing license is required for all anglers 16 and older; non-resident licenses are available for 3 days, 7 days, or a full year.

Seasonal Patterns Around Peanut Island

Spring (March through May) is peak season. Tarpon move through the inlet, snook are aggressive, and redfish are feeding heavily on the incoming tide. Water temperatures range from 72 to 78 degrees, and visibility is good. This is the best time for sight-fishing and for targeting multiple species in a single trip.

Summer (June through August) brings heat and afternoon thunderstorms, but early morning fishing is excellent. Snook are in a seasonal closure (June 1 to August 31), so focus on redfish, permit, and tarpon. Water temperatures exceed 85 degrees, and fish move deeper during the day. Fish early and late; midday is slow.

Fall (September through November) is productive again as water temperatures drop and baitfish return. Redfish and snook are aggressive, and permit are abundant on the deeper flats. Visibility improves as summer rain runoff clears. This is a second-best season after spring.

Winter (December through February) is slower but still fishable. Redfish remain active, snook move into deeper channels, and tarpon are absent. Water temperatures drop to 65 to 72 degrees, and fish are less aggressive. Midday fishing is better than early morning because water is warmer.

Frequently Asked Questions

Can I fish from shore near Peanut Island?

No public shore access exists near Peanut Island. The island itself is a protected park, and the surrounding shoreline is private or mangrove-lined. You must fish from a boat. The nearest shore fishing is at public parks in Lantana or Riviera Beach, which are several miles away and fish different water.

What is the best month to fish Peanut Island?

April and May are peak months. Tarpon are moving through the inlet, snook are aggressive, redfish are feeding heavily, and water clarity is excellent. Spring tide (the largest tidal swings) often occurs in April, which brings more water movement and more aggressive feeding.

Do I need a guide to fish Peanut Island?

No, but the lagoon is shallow and the channels are narrow, so local knowledge helps. If you are unfamiliar with the area, a guide can show you the best flats, teach you to read the water, and help you understand the tidal patterns. Several independent guides work the lagoon and can be found through local tackle shops.

What size boat do I need?

A 16 to 20-foot center-console or flats boat is ideal. Anything smaller is uncomfortable for a full day, and anything larger struggles in the shallow water around the island. A boat that draws less than 2 feet lets you fish the shallowest grass beds where redfish and snook are most abundant.

Is Peanut Island good for beginners?

Yes, if you have boat experience. The water is shallow and forgiving, redfish are abundant and not overly selective, and the tidal patterns are straightforward. Sight-fishing is challenging for beginners, but blind-casting along the mangroves and channel edges is productive. Start on an incoming tide in the morning, when fish are most active and the water is clearest.
