What You Can Fish at the Charlestown Navy Yard

The Charlestown Navy Yard sits on a working waterfront where the Mystic River meets Boston Harbor, and it holds striped bass, bluefish, and schoolie stripers year-round. The yard itself is a National Historic Site—you can walk the grounds and see the USS Constitution—but the real fishing happens along the perimeter where the water is accessible. Spring and fall bring the best action, when stripers move through the harbor on their seasonal migrations. Summer holds resident fish and smaller schoolies. Winter fishing is possible but inconsistent, depending on ice and water temperature.

Access is limited compared to other Boston-area spots. You cannot fish from the Navy Yard's interior docks or piers; those are restricted. Your options are the public walkway along the Mystic River side and the outer harbor edges where the park meets the water. The Mystic River side is more productive for stripers because the current and structure hold fish. The harbor side is shallower and better for bluefish and smaller stripers, especially in summer.

Key Takeaways

  • Striped bass and bluefish are the primary species, with spring and fall offering the most consistent fishing.
  • Access is limited to the public walkway along the Mystic River side and outer harbor edges; interior docks are off-limits.
  • The Mystic River side holds deeper water and structure that attracts larger stripers; the harbor side is shallower and better for schoolies.
  • Parking is available at the Navy Yard visitor center, but arrive early on weekends because spaces fill quickly.
  • Tide and current matter more here than at many other Boston spots because the Mystic River flow changes the water conditions throughout the day.

Best Times to Fish the Mystic River Side

The Mystic River side is where you want to be if you are targeting stripers. The river channel runs deep here, and the current brings baitfish and holds larger fish. Spring (April through May) is excellent—water temperatures are rising, stripers are moving north, and they feed aggressively. Fish the slack water near the pilings and along the edges of the current. Early morning and the last two hours of daylight are most productive.

Fall (September through October) is equally good, sometimes better. Stripers are moving south and feeding hard before the migration. The water is still warm enough to hold fish all day, but dawn and dusk are still your best windows. Summer (June through August) is slower for larger stripers, but schoolies are abundant and will take small plugs and soft plastics. Winter fishing is unpredictable; ice can form along the banks, and fish move deeper into the harbor.

Tide matters here more than at many other spots because the Mystic River flow is strong. Fish the incoming tide when the current pushes water up the river—this is when baitfish move and stripers feed. The slack water at the turn of the tide can also be productive, especially if you are working structure. Outgoing tide can be slow because the current pushes fish out into the harbor.

Harbor Side and Schoolie Fishing

The outer harbor side of the Navy Yard is shallower and more exposed to open water. This is where you find schoolie stripers and bluefish, especially in summer. The water here warms faster than the river side, and smaller fish move in to feed on sand eels and silversides. Schoolies will take small plugs (2 to 3 inches), soft plastics rigged on light jigs, and live shiners if you can get them.

Bluefish show up in summer and fall, and they are aggressive hunters. They will hit topwater plugs and metal spoons. The harbor side is also less crowded than the river side, so if you want to fish without an audience, this is your spot. The downside is that the water is shallower and clearer, so fish are spookier. Fish early and late, and use lighter tackle and longer casts.

How to Get There and Where to Park

The Charlestown Navy Yard is in Charlestown, just north of downtown Boston. The main entrance is at 1 Constitution Road, Charlestown, MA 02129. There is a visitor center and parking lot at the entrance. Parking is free, but spaces fill quickly on weekends and nice weather days. Arrive early if you are going on a Saturday or Sunday.

From downtown Boston, take the Green Line to the Community College stop, or drive north on the Fitzgerald Expressway (I-93) and take the exit for Charlestown. Once you park, walk to the Mystic River side by heading toward the water and following the public walkway. The walkway is paved and well-marked. The harbor side is accessible by walking around the perimeter of the yard, but it is less obvious—ask at the visitor center if you are unsure.

Public restrooms are available at the visitor center. There are no tackle shops inside the yard, so bring everything you need. The nearest tackle shops are in downtown Boston or across the river in Somerville.

Gear and Tackle for the Navy Yard

Bring a medium-action spinning rod (6 to 7 feet) with 10- to 15-pound braided line. This setup handles both stripers and bluefish and gives you the sensitivity to feel structure and current changes. For the Mystic River side, use 3/8- to 1/2-ounce jigs tipped with soft plastics (4 to 5 inches), or small plugs (2 to 3 inches). For the harbor side, go lighter—1/4-ounce jigs and smaller plugs work better in the shallower water.

Topwater plugs are effective at dawn and dusk, especially for bluefish. Metal spoons (Hopkins, Kastmaster) work year-round and are good for covering water quickly. If you want to throw live bait, shiners and mackerel work, but you will need a net or a way to keep them alive. The current here is strong enough that you need to stay vertical with your jig most of the time—casting and retrieving works, but jigging the drop is more effective.

Bring polarized sunglasses so you can see structure and baitfish. The water here is relatively clear in spring and fall, and you can spot stripers hunting. Waders are not necessary—you are fishing from the walkway and shore—but wear shoes with good grip because the pavement can be slippery when wet.

Rules and Restrictions at the Navy Yard

The Charlestown Navy Yard is a National Historic Site, and fishing is allowed only in designated areas. You cannot fish from the interior docks, piers, or any part of the active shipyard. Stick to the public walkway along the Mystic River and the outer harbor edges. Rangers patrol the yard, and they will ask you to leave if you are in a restricted area.

Massachusetts fishing regulations apply. You need a fishing license if you are 16 or older. Striped bass have a minimum size of 18 inches and a daily limit of one fish per person (as of 2024, but check the current regulations before you go). Bluefish have no size restriction and a daily limit of 10 fish. Catch-and-release is always an option if you want to fish without keeping anything.

The yard is open dawn to dusk. Fishing after dark is not allowed. The visitor center has information about the historic site and can answer questions about access and rules.

Why the Navy Yard Fishes Well Despite Urban Location

The Charlestown Navy Yard works as a fishing spot because it sits at the confluence of the Mystic River and Boston Harbor. This geography creates structure, current, and baitfish concentration. The river channel is deep, and the current brings food. The pilings and seawalls provide cover for stripers. The water here is cleaner than it was 20 years ago, and fish populations have recovered.

The urban setting is actually an advantage in some ways. The yard is easy to reach by car or public transit. You do not have to drive an hour to find stripers. The crowds are manageable compared to Cape Cod or Rhode Island beaches. And because many anglers assume urban fishing is poor, the Navy Yard gets less pressure than it deserves. If you know what you are doing, you can catch fish here consistently.

Frequently Asked Questions

Do I need a Massachusetts fishing license to fish at the Navy Yard?

Yes, if you are 16 or older. You can get a license online through the Massachusetts Division of Fisheries and Wildlife website, or at most tackle shops and sporting goods stores. A one-day license costs less than a full-year license if you only plan to fish once.

What is the best tide for fishing the Mystic River side?

Incoming tide is usually best because the current brings baitfish and pushes stripers into feeding mode. The slack water at the turn of the tide can also be productive. Outgoing tide is slower because fish move out into the harbor with the current.

Can I fish at night at the Charlestown Navy Yard?

No. The yard closes at dusk, and fishing after dark is not allowed. Plan your trip for early morning or late afternoon if you want to fish the best hours.

Are there tackle shops near the Navy Yard?

There are no shops inside the yard. The nearest tackle shops are in downtown Boston and Somerville, across the Mystic River. Bring all your gear with you.

What size stripers can I keep at the Navy Yard?

The minimum size is 18 inches, and the daily limit is one fish per person (check current Massachusetts regulations before you go, as these can change). Bluefish have no size restriction and a 10-fish daily limit.
