Your Weekender: Family Activities in Boston, July 13-19

BOSTON, A slew of family-friendly events kicks off this week across Greater Boston, with options ranging from free outdoor film screenings in the Common to discounted admission at the Museum of Science. The city's summer programming is in full swing, and families looking to beat the heat, or simply find an inexpensive afternoon out, have plenty of choices.

This roundup comes as global headlines grow heavy: a major fire in Bangkok, escalating U.S.-Iran tensions, wildfires near Paris and in Spain, and the sudden death of a U.S. senator. At home, summer remains a time for Bostonians to reclaim public spaces and connect with neighbors. Local officials have emphasized the importance of community resilience, and this week's activities offer a chance to step away from the news cycle and enjoy the season.

Free Outdoor Screenings and Concerts

The Boston Parks & Recreation Department continues its “Summer in the City” series, which includes free movies and concerts in neighborhoods from East Boston to Hyde Park. This Thursday, July 16, the Hatch Memorial Shell on the Charles River Esplanade will host a performance by the Boston Pops at 7 p.m., a tradition that dates back to 1929. Admission is free on a first-come, first-served basis; blankets and picnics are welcome.

On Friday, July 17, the Boston Common Frog Pond will screen Encanto (PG) starting at dusk, around 8:30 p.m. The city estimates that each screening draws up to 3,000 attendees. No registration is required, though early arrival is recommended for a good spot on the lawn.

For those seeking a quieter evening, the Arnold Arboretum in Jamaica Plain offers its “Summer Twilight Walks” on Saturday, July 18, from 6 to 8 p.m. The free guided tour is limited to 40 participants; registration opens online at noon on the Monday before the walk.

Museum Discounts and Indoor Cool-Downs

With temperatures forecast to reach 90°F on Wednesday and Thursday, air-conditioned museums become prime real estate. The Museum of Science, located on the Charles River Dam, continues its “Summer Science” program: children ages 3-11 receive half-price admission ($12 instead of $24) with a paying adult through August 31. The offer is available only at the box office, not online, and excludes IMAX and Planetarium tickets.

The New England Aquarium on Central Wharf offers “Family Fun Fridays” through August 28, during which a family four-pack (two adults, two children) costs $89, a savings of about $30 off regular ticket prices. The aquarium notes that its jellyfish exhibit, “Spineless Wonders,” has been extended through September due to popular demand. Advance reservation is strongly recommended; walk-up availability is limited to 50 tickets per hour.

Additional options: The Isabella Stewart Gardner Museum in the Fenway neighborhood offers free admission to anyone named Isabella on July 16, as part of its “Name Day” tradition. (Proof of ID with the name is required.) And the Harvard Museum of Natural History in Cambridge runs its “Nature 101” scavenger hunt every Saturday through August 29, free with paid admission ($15 adults, $10 children 3-18).

For families seeking a free indoor option, the Boston Public Library’s central branch in Copley Square hosts “Story Time for All Ages” on Wednesday, July 15, at 10:30 a.m. in the Children’s Room. No tickets are needed.

Practical advice: Most of these events operate on a first-come, first-served basis, so arrive early. For outdoor screenings, bug spray and a blanket are essential. Check @BostonParksDept on X (formerly Twitter) for weather cancelations, a 60 percent chance of isolated thunderstorms is forecast for Saturday afternoon. The city does not announce rain dates until 24 hours before; if a screening is canceled, funds and reservations for ticketed events are typically refunded or honored on a new date.
