The 10 best free things to do in Boston
This list covers ten places inside the City of Boston that cost nothing to visit, from Charlestown to Jamaica Plain and South Boston. It is written for visitors watching a budget and for residents looking for a weekend plan that does not involve a ticket counter.
The list favors public parks, trails, government buildings and national park sites that are free every day they are open. One museum is included because admission is waived at a set time each week, and that time is stated in the entry. Paid extras, such as guided walking tours, a zoo or a museum along a free trail, are named where they come up.
How we chose
The list is alphabetical, not ranked. Each place had to be inside the Boston city limits, open to the public as of November 2026, and free to enter either at all times or at a stated weekly time. Details were checked against the pages of the agency or organization that runs each site, including the National Park Service, the City of Boston, the Commonwealth of Massachusetts and Harvard University. Places open year-round were favored, and seasonal programs are marked as seasonal.
Hours and prices below come from each business and change without notice. Call ahead if you are making a special trip.
Arnold Arboretum
Harvard University runs this 281-acre collection of trees and shrubs in Jamaica Plain, and the gates are open to anyone at no charge. The arboretum’s visitor page lists admission as always free, with the grounds open every day from sunrise to sunset. Founded in 1872, the landscape works as both a research collection and a public park, so most plants carry labels with their names. The visitor center is the place to pick up a map and ask about guided walks, which include an introductory tour and an Explorers Garden tour. Self-guided and virtual walks are also listed for people who would rather set their own pace.
Hours: Landscape open daily, sunrise to sunset. Visitor center open daily, 10 a.m. to 4 p.m.

Boston African American National Historic Site
On the north slope of Beacon Hill, the National Park Service maintains the Black Heritage Trail, a walk of about 1.5 miles through the neighborhood where Boston’s Black community lived in the 1800s. The route covers the Underground Railroad, the abolition movement and early civil rights campaigns. Walking it is free, and the NPS App has a self-guided version that works any day. Rangers lead tours in the warmer months only. Most buildings on the trail are privately owned and closed to the public, so the walk is an outdoor one. The Museum of African American History at 46 Joy Street charges separate admission. Sidewalks are narrow and uneven in places.
Hours: Self-guided trail open any time, seven days a week. Ranger-led tours ran Wednesday through Sunday at 10 a.m. and 1 p.m. from May 23 to September 27, 2026, with advance registration required.

Bunker Hill Monument
A 221-foot granite obelisk marks the Charlestown hill where colonial and British forces fought in June 1775. The National Park Service charges nothing to enter the grounds, the museum across the street or the monument itself. Climbing to the top means 294 steps up a tight spiral stairway with no elevator. Climbers enter through the Bunker Hill Lodge at the base, and only 25 people are allowed inside at a time, so a wait is possible on busy days. The park service may close the stairs for weather or other safety reasons. The lodge and the base of the monument are accessible to visitors who skip the climb.
Hours: Check current hours before you go.
Address: Monument Square, Charlestown; the Bunker Hill Museum is at 43 Monument Square, Charlestown, MA 02129

Castle Island and Fort Independence
South Boston’s harbor edge ends at this 22-acre state park, which is joined to the mainland by roads and walkways despite the name. The centerpiece is Fort Independence, a five-sided granite fort built between 1834 and 1851 on a site that has held fortifications since 1623. A short loop circles the fort, and a longer walk follows the causeway around Pleasure Bay. The state lists the park as open from sunrise to sunset, with a free parking lot near the fort. Volunteers give free tours of the fort’s interior in summer and early fall only, weather permitting. The 2026 season has ended, so a November visit means the outside walls and the harbor view.
Hours: Sunrise to sunset. Fort tours are seasonal, on weekend afternoons from June into October.

Walking, running and picnicking are free; the city requires permits for organized picnics and events. Two attractions inside the park boundary, the Franklin Park Zoo and the William J. Devine Golf Course, charge their own fees. The city has an action plan for the park, so some areas may be under improvement.
