What You'll Find at Coskata-Coatue

Coskata-Coatue Wildlife Refuge is a 1,100-acre barrier beach and saltmarsh complex on the northeastern tip of Nantucket Island, managed by the Massachusetts Audubon Society. The refuge protects a working landscape of tidal flats, salt marshes, and sandy beaches that draw striped bass, bluefish, and weakfish in season, along with nesting shorebirds and migratory waterfowl. Access is limited to protect breeding habitat, but fishing is permitted in designated areas during specific times of year.

The refuge sits at the convergence of Nantucket Harbor and the Atlantic, creating rich feeding grounds for both fish and birds. The shallow tidal flats and marsh channels hold schooling fish in spring and fall, while summer brings calmer conditions and smaller resident populations. Winter access is restricted entirely to allow undisturbed roosting and feeding for overwintering species.

Key Takeaways

  • Fishing is permitted only from June through October in designated areas, with access restricted to protect nesting shorebirds in spring and early summer.
  • A parking permit and day-use fee are required; permits are sold at the refuge gatehouse on a first-come, first-served basis during operating hours.
  • Striped bass and bluefish are the primary target species, with best results on the ocean-facing beaches and in tidal channels during moving water.
  • Wading and walk-in access are the only methods allowed; no motorized boats or vehicles are permitted within the refuge boundaries.
  • Massachusetts fishing regulations apply, including current saltwater licensing requirements and species-specific size and bag limits.

Seasons and Access Rules

The refuge operates on a seasonal access schedule tied to shorebird nesting and migration. From June through October, day-use access is open to the public, including anglers. November through May, the refuge is closed to protect nesting terns and plovers in spring and fall migrants and wintering waterfowl in winter. This closure is firm—no exceptions are made for fishing during the off-season.

During the open season, you must enter through the gatehouse on the western side of the refuge. A day-use parking permit is required and costs a modest fee; permits are sold on-site during gatehouse hours, typically 9 a.m. to 5 p.m. daily. Arrive early on weekends, as the refuge limits daily vehicle entries and permits sell out. The gatehouse staff can tell you current conditions, recent fish activity, and which areas are open that day.

Once inside, you are restricted to foot traffic only. No motorized boats, kayaks, or vehicles are allowed beyond the parking area. Wading and shore fishing are the only methods permitted. Dogs are prohibited year-round to protect nesting and roosting birds.

Where to Fish and What Species to Target

The refuge's best fishing grounds are the ocean-facing beaches on the eastern and northern shores, where striped bass and bluefish move in and out with the tide. The tidal flats adjacent to the marsh channels also hold weakfish and smaller stripers during summer and early fall. The western side, facing Nantucket Harbor, is calmer and produces fewer fish but can be productive during slack tide when baitfish concentrate.

Striped bass are the primary target from June through September, with peak activity in June and September when water temperatures are moderate and baitfish are abundant. Bluefish arrive in July and remain through October, feeding aggressively on the shallow flats during incoming tide. Weakfish are present but less reliable; they prefer deeper channels and are more active at dawn and dusk.

Tidal movement is critical. Fish feed most actively during the first two hours of incoming tide and the last two hours of outgoing tide. Slack water—the period between tides—is typically slow. Plan your visit around tide tables; the refuge gatehouse often has printed tide charts, or check online before you go.

Tackle and Techniques

Light to medium spinning tackle works well for striped bass and bluefish on the flats. Bring 6- to 8-pound test line and a selection of small topwater plugs, soft plastics in white or chartreuse, and small metal spoons. Live bait—sand eels, silversides, or small mackerel—is effective but requires a bait net or purchase from a local tackle shop. Check current regulations on bait transport and storage before you arrive.

Wading is the primary fishing method. The bottom is sandy and relatively even, but wear wading shoes or boots to protect your feet from shells and sharp rocks. Water depth rarely exceeds waist-deep on the flats, but currents can be strong during peak tidal flow. Stay aware of your position relative to the tide line; incoming water can cut off your exit route if you wade too far out.

Fly fishing is permitted and can be productive for stripers and bluefish on the flats. Bring 8- to 10-weight rods and a selection of baitfish patterns in sizes 2 to 4. The shallow, clear water rewards accurate casting and a slow retrieve.

Regulations and Licensing

Massachusetts saltwater fishing regulations apply throughout the refuge. You must possess a current Massachusetts Saltwater Fishing License if you are 16 or older. Licenses are sold online through the Massachusetts Division of Marine Fisheries website, at tackle shops throughout Nantucket, and sometimes at the refuge gatehouse. A three-day temporary license is available if you do not want to purchase an annual permit.

Striped bass have a 19-inch minimum size and a two-fish daily bag limit. Bluefish have a 12-inch minimum and a ten-fish daily bag limit. Weakfish have a 12-inch minimum and a five-fish daily bag limit. These limits change periodically; check the current regulations before you fish. The refuge gatehouse staff can confirm current rules, or visit the Division of Marine Fisheries website.

Catch-and-release is encouraged for all species, particularly for striped bass, which support a valuable recreational fishery across the region. Handle fish carefully if you plan to release them, and wet your hands before handling to protect their protective slime coating.

Getting There and What to Bring

Coskata-Coatue is located on Nantucket Island, accessible by ferry from Hyannis (about 1 hour) or by air. Once on Nantucket, the refuge is a 20-minute drive from the ferry terminal. Follow signs toward Wauwinet; the refuge entrance is at the end of Wauwinet Road. Parking is available at the gatehouse, and the day-use fee covers parking and refuge access.

Bring sunscreen, a hat, and plenty of water—the open beach offers no shade and sun exposure is intense. Bring a tide table or check tides online before you arrive. Wading shoes or boots are essential. A small cooler for keeping fish fresh is useful if you plan to keep your catch. Insect repellent is wise in summer, particularly in early morning and evening when mosquitoes and biting flies are active in the marsh areas.

The nearest tackle shops are in Nantucket town, about 20 minutes away. Stock up on bait and tackle before heading to the refuge, as no supplies are available on-site. The gatehouse can provide recommendations for local shops and current fishing reports.

Why This Refuge Matters for Fishing

Coskata-Coatue protects one of the last large saltmarsh complexes on the Atlantic coast. The refuge's tidal flats and marsh channels are nursery habitat for juvenile fish and feeding grounds for migratory species. By limiting access and restricting fishing seasons, the refuge maintains the ecological health of the system—which in turn supports the fish populations that make it worth visiting.

The refuge also protects critical nesting habitat for piping plovers, least terns, and common terns, species that have declined sharply due to human disturbance and habitat loss. The seasonal closures and access restrictions you encounter as a fisher are direct results of these conservation needs. Understanding that trade-off—fewer fishing days in exchange for a healthy, productive fishery—is part of fishing responsibly in a protected area.

Frequently Asked Questions

Can I fish here in winter?

No. The refuge closes to all public access from November through May to protect wintering waterfowl and spring-nesting shorebirds. Fishing is permitted only from June through October. If you want winter saltwater fishing on Nantucket, look for public beaches and jetties outside the refuge.

Do I need a boat to fish here?

No. Motorized boats and kayaks are not permitted. Wading and shore fishing are the only methods allowed. The shallow tidal flats are actually ideal for wading anglers, and you can reach productive water without a boat.

What if the gatehouse is closed when I arrive?

The gatehouse operates during standard day-use hours, typically 9 a.m. to 5 p.m. If you arrive outside those hours, you cannot enter. Plan your visit during posted hours. Call ahead if you are unsure about current operating times, particularly in shoulder seasons.

Are there fish here in June, or should I wait until July?

June can be excellent for striped bass, particularly in the first half of the month when water temperatures are moderate and baitfish are moving through. Bluefish typically arrive in July. If you can only visit in June, focus on the ocean-facing beaches during tidal movement.

Can I keep fish I catch here?

Yes, as long as they meet size and bag limits under Massachusetts regulations. Striped bass must be at least 19 inches and you can keep two per day. Bluefish must be at least 12 inches with a ten-fish daily limit. Keep only what you plan to eat, and handle fish carefully if you decide to release them.
