The 16 Best Attractions in Boston

The oldest ballpark in Major League Baseball and beloved home of the Red Sox, famous for its towering Green Monster left-field wall. Catching a game is a classic Boston experience, and daily tours run when the team is away. Tickets are among the priciest in baseball and seats can be cramped in the century-old stands.

A 2.5-mile red-brick path linking 16 of Boston's most important Revolutionary-era sites, from Boston Common to the Bunker Hill Monument. Following it on your own is free and the single best way to orient yourself in the city's history. It gets crowded in summer and the full walk with stops takes the better part of a day.

The historic core of Harvard University in Cambridge, a leafy quad of red-brick halls anchored by the John Harvard statue that visitors rub for luck. Strolling the Yard is free and student-led tours bring it to life. It's a working campus, busiest and most restricted during term-time exam periods.

A stunning 1831 garden cemetery in Cambridge, and a genuine local secret: 175 acres of arboretum, birdwatching, and hilltop views, free to walk. Not a tourist trap, an actual sanctuary. Closed Sundays; open Mon-Sat with early-bird spring hours.

Old Ironsides is the world's oldest commissioned warship still afloat, a three-masted 1797 frigate you can board for free in the Charlestown Navy Yard. Active-duty sailors give tours and the adjacent museum fills in the history. You'll need a photo ID for the security check and the ship occasionally closes for maintenance.

The 1895 McKim building in Copley Square is a palatial free landmark, with the barrel-vaulted Bates Hall reading room, murals and a serene Italianate courtyard. Free guided art-and-architecture tours run daily. It's a working library, so quiet is expected and the courtyard closes in winter.

A three-story stained-glass globe built in 1935 that visitors walk through on a glass bridge, experiencing the world as it was politically mapped at that moment — a genuinely singular architectural and historical artifact. The acoustics create a whispering-gallery effect where sounds travel across the sphere in uncanny ways. Guided tours run throughout the day and last about 30 minutes. It is consistently underrated and rarely crowded despite being steps from the Prudential Center.

A constellation of 34 islands accessible by ferry from Long Wharf offering beaches, Civil War-era Fort Warren on Georges Island, camping on Lovells Island, and sweeping skyline views unavailable from anywhere on the mainland. Georges Island is the main hub and free once you pay the ferry; Spectacle Island has the best swimming beach and a café. The ferry schedule is seasonal and limited — check times carefully or you will miss the last boat back. This is Boston's best-kept open secret.

A 221-foot granite obelisk in Charlestown marking the 1775 battle. Free to climb its 294 steps for a rooftop city view, no elevator. Free timed tickets from the lodge. Open Wednesday-Sunday, so plan around the closed days.

One of the largest and most encyclopedic art museums in the United States, with world-class collections spanning ancient Egypt, Japanese art, Impressionism, and contemporary work. The American Wing and the Nubian collection are particular strengths that rival any museum globally. Wednesday evenings offer pay-what-you-wish admission after 4pm. The sheer scale can be overwhelming — pick two or three wings rather than attempting everything.

Harvard's natural history museum houses the legendary Glass Flowers — 4,300 botanically accurate glass models made by Leopold and Rudolf Blaschka between 1887 and 1936 — alongside impressive dinosaur skeletons, gemstone collections, and taxidermy. The Glass Flowers alone justify the trip; they remain scientifically and artistically inexplicable. Massachusetts residents get free admission on Sundays from September through May. The building is old and not fully climate-controlled, which adds to its charm.

Boston's oldest surviving church (1723), from whose steeple the 'one if by land, two if by sea' lanterns signaled Paul Revere's ride. The pretty Georgian interior with its box pews is worth a look. There's a small admission or suggested donation, and it's a compact stop on a busy North End street.

A masterpiece of Richardsonian Romanesque architecture on Copley Square, consistently ranked among America's finest buildings, with a richly decorated interior and John La Farge murals. Self-guided visits carry a modest fee. It's an active parish, so parts may be closed during services and events.

Relocated to a striking new building in Kendall Square in 2022, the MIT Museum showcases robotics, holography, artificial intelligence, and the history of invention in an interactive, intellectually playful environment. The holography collection is the largest publicly accessible one in the world. Exhibits change frequently and skew toward hands-on engagement rather than passive viewing. It sits in the heart of the innovation district, making it easy to combine with a campus walk.

A mile-and-a-half linear park built over the Big Dig tunnel that stitched together neighborhoods severed by the old elevated highway, running from Chinatown through Downtown to the North End. Rotating public art installations, a carousel, seasonal food trucks, and a beer garden make it a genuine civic gathering space rather than just a green corridor. The Rings Fountain is a favorite with kids in summer. It is best experienced on a weekday when office workers thin out and the art is easier to appreciate.

A downtown waterfront aquarium built around a four-story Giant Ocean Tank you spiral up around. Great with kids. Adult tickets run about $33 with timed entry, so book online ahead; weekends sell out. New England residents get $5 off.
