What Hermit Island Offers and How to Fish It

Hermit Island is a small, rocky outcrop in Casco Bay off Phippsburg that holds striped bass, bluefish, and mackerel in season. You cannot land on the island itself—it's privately owned and closed to the public—but you can fish the waters around it from a boat. The island sits roughly two miles offshore and works best on the incoming tide when baitfish move through the channels. Most anglers fish it as part of a broader Casco Bay trip rather than making it a solo destination, since the island alone is small and the bite can be inconsistent depending on season and water conditions.

Access requires your own boat or a charter out of nearby Harpswell or Brunswick. The island is marked on GPS and nautical charts, making it straightforward to locate once you're on the water. Depths around the island range from 15 to 35 feet, with the best structure on the eastern and southern sides where rocks create current breaks. Stripers here run 18 to 30 inches on average, with occasional fish pushing into the 35-inch range during spring and fall migrations.

Key Takeaways

  • Hermit Island is a private, no-landing rocky island in Casco Bay that you fish from a boat, not from shore.
  • Striped bass, bluefish, and mackerel are the primary species, with the best fishing during spring and fall when baitfish are moving through the bay.
  • Incoming tide and early morning light produce the most consistent results around the island's rocky structure.
  • You will need your own boat or a charter service; there is no public dock or shore access to the island itself.

Seasonal Patterns and Timing

Spring (April through May) brings the first strong striped bass bite around Hermit Island as fish move into Casco Bay from offshore wintering grounds. Water temperatures in the low 50s trigger feeding, and the incoming tide concentrates baitfish around the rocks. Early morning—first light through mid-morning—is when you'll see the most activity. Slack tide and outgoing water often slow the bite considerably.

Summer (June through August) can be hit or miss. Stripers disperse into deeper water and cooler channels as the bay warms, so Hermit Island becomes less reliable. Mackerel and bluefish are more consistent during this period, and night fishing around the rocks can produce stripers when daytime bites are slow. Water temperatures in the upper 60s and low 70s push fish to seek cooler structure.

Fall (September through October) is the strongest season. Stripers return to the shallower bay structure as water cools, and the island becomes a reliable waypoint on the migration route. Baitfish congregate in the same areas, and you can expect steady action on incoming tides. October often produces the largest fish of the year as pre-winter feeding intensifies.

Winter (November through March) is slow and risky. Water temperatures drop into the 30s and 40s, fish move to deeper channels, and weather makes boat access difficult. Most anglers avoid Hermit Island during this period in favor of more protected or productive water.

Tackle and Bait That Work Here

Live mackerel and herring are the top baits for striped bass around Hermit Island. Mackerel especially holds up well in the current and attracts larger fish. Fish them on a simple two-hook rig with a 2 to 3-ounce sinker to keep the bait near bottom structure in 20 to 30 feet of water. A 6 to 7-foot medium-heavy rod with 20-pound braided line gives you the sensitivity to feel the bottom and the backbone to set the hook in current.

Artificial lures work well on the incoming tide when stripers are actively feeding. Swim shads in the 4 to 5-inch range—white, pearl, or natural colors—mimic the baitfish moving through the bay. Jigging spoons (1 to 2 ounces) work when fish are suspended or when you want to cover water quickly. Cast along the rocky edges and work the lure with a steady retrieve or a jigging motion depending on depth and current speed.

For bluefish and mackerel, small metal jigs, spoons, and topwater plugs all produce. Bluefish will hit almost anything moving, but mackerel require a faster retrieve and smaller profile. Bring a mix of lure weights and colors so you can adjust to the tide and light conditions.

Tides, Currents, and When to Fish

The incoming tide is the primary window for Hermit Island. As water pushes into Casco Bay, baitfish move through the channels around the rocks, and stripers position themselves to intercept them. The first two hours of the incoming tide and the hour before slack high are usually the most productive. Current speed matters—a moderate, steady flow is better than a ripping tide that makes holding bottom difficult.

Slack tide (the brief period between incoming and outgoing) can be productive if baitfish are still in the area, but the bite often slows as current stops. Outgoing tide generally produces less, though early outgoing can still hold fish if the tide change is recent. Plan your trip to arrive at the island 30 to 45 minutes before the tide starts coming in, so you're positioned and ready when the bite begins.

Water clarity affects visibility and feeding behavior. Clear water (visibility beyond 10 feet) is ideal for sight-casting and lure fishing. Stained water (3 to 8 feet visibility) is common in Casco Bay and still productive, especially with live bait. Very murky water (under 3 feet) can slow the bite, though it sometimes concentrates fish tighter to structure.

Getting to Hermit Island by Boat

From Phippsburg, the nearest public boat launch is at Cundy's Harbor, roughly 4 miles south of the town center. The launch has a paved ramp, parking for trailers, and a small dock area. From Cundy's Harbor, Hermit Island is about 3 miles northeast across open water. The run takes 10 to 15 minutes depending on sea state and your boat speed.

Harpswell, just north of Phippsburg, offers additional launch options at Harpswell Town Landing and several private marinas. These are slightly closer to Hermit Island (roughly 2 to 3 miles) and can save fuel and time. Check with the town or marina for current launch fees and hours before you go.

Charter services operating out of Harpswell and Brunswick regularly fish Hermit Island as part of their Casco Bay trips. A half-day charter typically includes the island plus other nearby structure and costs between $400 and $600 for two anglers. Charters handle navigation, know the current bite, and can save you time if you're unfamiliar with the area or don't own a boat.

Nautical charts (NOAA Chart 13288 covers Casco Bay) show the island clearly, and GPS coordinates are widely available online. The island is marked by a small light structure, making it easy to spot in daylight. Approach from the south or east to avoid shallow water on the western side.

Safety and Regulations

Casco Bay can develop rough conditions quickly, especially in spring and fall when weather systems move through. Check the marine forecast before you leave, and don't hesitate to stay ashore if winds are forecast above 15 knots or seas are building. The island offers no shelter, so you're exposed to whatever weather develops.

Wear a Coast Guard-approved personal flotation device at all times on the water. Hermit Island sits in a shipping lane for larger vessels heading to Portland, so stay alert and keep your radio on Channel 16. Small boat traffic is common, especially on weekends.

Maine requires a saltwater fishing license for anyone 16 and older. You can purchase a short-term license (three days or seven days) online through the Maine Department of Inland Fisheries and Wildlife or at most tackle shops in the area. Striped bass have a 19-inch minimum size and a one-fish daily limit in Maine. Bluefish and mackerel have no size or bag limits.

Other Nearby Water Worth Fishing

If Hermit Island is slow or weather prevents you from reaching it, several alternative spots in Casco Bay hold the same species. Bustins Island, just south of Hermit Island, has similar rocky structure and often fishes just as well. The deeper channels between Phippsburg and Harpswell hold stripers during summer when the shallower areas warm up. Eagle Island and the waters around it produce bluefish and mackerel consistently through the season.

The New Meadows River, which borders Phippsburg to the north, offers a protected alternative when bay conditions are rough. The river holds stripers in spring and fall, especially around the deeper holes near the mouth. You can launch at the New Meadows River boat launch in Brunswick and fish the river without dealing with open-water conditions.

Frequently Asked Questions

Can I fish Hermit Island from shore?

No. The island is privately owned and closed to public landing. You must fish from a boat anchored or drifting around the island's perimeter. Shore fishing is not an option here.

What's the best tide for Hermit Island?

The incoming tide is almost always best, especially the first two hours as water begins to flow into the bay. Fish the hour before slack high tide as well. Outgoing and slack tides are usually slower.

Do I need a boat to fish here, or can I hire a charter?

You can do either. If you own or have access to a boat, you can launch from Cundy's Harbor or Harpswell and fish on your own. Charter services out of Harpswell and Brunswick fish Hermit Island regularly and handle navigation and tackle advice.

What size stripers should I expect?

Most fish run 18 to 30 inches. Larger fish (35+ inches) show up during spring and fall migrations, but they're less common. The island is better for consistent action on keeper-size fish than for trophy hunting.

What happens if the weather turns bad while I'm out there?

Hermit Island offers no shelter. If conditions worsen, head back to the nearest harbor—Cundy's Harbor or Harpswell are both close. Check the marine forecast before you leave and don't stay out if winds or seas are building.
