The best family weekends in Boston are the free ones: a neighborhood shuts a street, opens its studios or puts bands on its porches. SoWa's Sunday market runs from spring to late autumn and needs no booking at all. The autumn circuit and Head of the Charles fill October.
Season: May–Nov · Updated October 21, 2026 · refreshed weekly

“One of the largest open-air farmer and artist markets in Boston” — regional and local vendors, food and beverage trucks, all of it among working artist studios, galleries and shops.
Free
Families who want a plan that never needs checking first

Free
Any family, and especially one that has been putting off the pricier museums
The regatta turns three miles of riverbank into the busiest weekend of the Boston autumn, Friday to Sunday in October. Crews come past in a long procession rather than one race, so you walk the bank rather than take a seat.
