Central Square's main public plaza at Massachusetts and Western Avenues, named for local businessman Carl Barron; the city is currently in the process of redesigning it as an investment in the square's public realm.
What to expect
Entry fee
Cambridge has no parking sticker program for its parks and no municipal swim beach; Fresh Pond is a drinking-water reservoir where swimming and wading are prohibited. No pass or permit required.
Dogs
Cambridge requires dogs to be leashed, on a leash no longer than six feet, whenever off the owner's premises and not under direct control in a designated off-leash area. That's the town-wide default; watch for posted signs here.
Hours
Cambridge parks and playgrounds are open dawn to dusk year round, with extended hours to 10:00 p.m. from April 1 through October 31. Posted hours at the entrance win if they differ.
