Facts, fees and hours were checked on 9 September 2026 against the National Park Service and the sites themselves; sources are listed at the end.
The Freedom Trail is 2.5 miles long, marked by a red brick or painted line through downtown, the North End and Charlestown, with sixteen sites from Boston Common to the Bunker Hill Monument. The park service gives a visit-duration range of "2–12 hours" — a range that includes time exploring the sites, not a walking time — which is the honest answer to how long it takes with children: it depends entirely on how many doors you go through. So this guide does not treat the trail as one walk. It treats it as pieces of the trail, each with a free version, plus two outings just off it.
Which piece fits today?
| If today you have… | Choose | What it asks of the group | Cost |
|---|---|---|---|
| A gentle morning | Boston Common and the State House — the park where the trail begins, the golden dome above it; Acorn Street and Beacon Hill's residential streets as optional detours | Open park paths with some slopes; the optional detours are steep, on cobbles and uneven brick | Free |
| An hour between other things | The downtown trail — Granary, Old South, Old State House, the Massacre site, Faneuil Hall | Short blocks, stairs at some sites, busy crossings | Free outside; two paid partner sites |
| Patience for narrow streets | The North End — Paul Revere's house, Old North Church, Hanover Street | Narrow sidewalks, crowds; two small paid sites | Free to walk; admission charged separately at each site |
| Fresh legs and a clear day | Charlestown — the monument, the ship, the Navy Yard | A 294-step climb (if open) and a ship with a tide-dependent ramp | Free to climb the monument and board the ship; the ship's museum is separately operated |
Free, paid, and where the passes don't work
The park service is precise about this: "There are no fees at the federally or municipally owned historic sites within Boston National Historical Park. This includes Faneuil Hall, Bunker Hill Monument, Bunker Hill Museum, USS Constitution, and Dorchester Heights." Four sites on the trail are run by independent non-profits and charge admission — Old South Meeting House, the Old State House, the Paul Revere House and Old North Church — and national park passes are not accepted at them. Ranger-led tours and programs are free. Most sites are open year-round with hours that change by season; peak season is May through October, and the park's hours page is the place to check on the day.
The Common and the State House, with Beacon Hill as a detour
Boston Common is America's oldest public park, set aside in 1634, and it is where the red line begins. It is the gentle piece: open park paths, with some slopes, free, with the Soldiers and Sailors Monument on its rise and the State House's golden dome above it — the trail's first stops. Acorn Street and the residential streets explored here are optional detours from the marked trail: brick sidewalks, gas lamps, purple window glass, steep and uneven underfoot, and what the Adventure Quest Beacon Hill adventure is built around. Take them if the group has the legs, and come back to the red line when it doesn't.
The downtown trail and Faneuil Hall
Between the Common and the North End the trail passes the Granary Burying Ground, Old South Meeting House, the Old State House, the Boston Massacre site and Faneuil Hall — the stretch the free Freedom Trail Explorer adventure follows. Faneuil Hall is free, has an elevator, restrooms, drinking water and rangers on hand, which makes it the natural midpoint for a family. The park service's own guidance on the trail is that stairs at several sites mean detours for wheelchairs and strollers; plan the stops, not just the route. Old South and the Old State House charge admission (prices not listed here — check their sites), and the park service names the Old State House among the sites that remain inaccessible.
The North End
Boston's oldest neighbourhood is the trail's tightest: narrow streets, crowded sidewalks, and two small paid sites, each with its own admission, worth deciding about in advance. The Paul Revere House charges $6 for adults, $5.50 for seniors and college students and $1 for children aged 5–17; it is open 10 a.m. to 5:15 p.m. from 15 April to 31 October and 10 to 4:15 the rest of the year, closed Mondays in January, February and March and on four holidays. Old North Church's self-guided Discovery Pass — sanctuary, crypt, audio guide and a family scavenger hunt — is $10 for adults, $5 for youth and free for children five and under, or $15/$10 with the 25-minute bell-chamber tour; hours are 10–5 Monday to Saturday and 12:30–5 on Sundays. Hanover Street, the feast days and the neighbourhood's Italian century are the rest of the North End adventure.
Charlestown: the monument and the ship
Across the bridge, the trail ends at the Bunker Hill Monument, a 221-foot granite obelisk with 294 steps to the top. The climb is free, and so is the Bunker Hill Museum across the street — but the park warns that the monument "may close for climbing due to weather conditions and/or other safety considerations," so check the day's hours before promising the view to anyone. Rangers give talks at the monument; current times are on the park's hours page.
Boarding USS Constitution, "Old Ironsides," is free, but the ship is "open on a limited schedule"; everyone 18 and older must show a physical, government-issued photo ID (the Navy does not accept digital IDs), the ship's active-duty crew guide visitors on a first-come basis, and the ramp to the top deck depends on the tide. The USS Constitution Museum beside it is separately operated, with its own admission arrangements — check its site (ussconstitutionmuseum.org) before you count it as part of the free day. The neighbouring USS Cassin Young is closed for maintenance through September 2026. Plan the ship around the Navy's current schedule, not around your afternoon.
The harbor: an outing of its own
The Harbor & Waterfront adventure is a separate outing from following the red line. It walks the water where much of the trail's story happened — the harbor the tea went into, the Navy Yard where Old Ironsides is moored, the working Fish Pier — and it is the one to keep for the end of a day when the light is low. Check the adventure's route for the walking it asks before promising it to the group.
Take the outing with you
Start with the free one. The Freedom Trail Explorer adventure follows the red line from the Common to Faneuil Hall in eight small missions and costs nothing. The Boston collection adds four more — Beacon Hill and the Common, the North End, the Harbor and Waterfront, and Charlestown and the Navy Yard — each eight missions to notice, find and photograph things at the place itself, six of which finish the adventure. Two of them — Beacon Hill and the Harbor & Waterfront — extend beyond the marked route.
