As part of its Take a Trip Up the Charles campaign, the Charles River Regional Chamber has created an online travel guide to Newton describing “a dream day in Newton” and listing 130 restaurants, 84 retail shops, and 7 hotels — as well as a link to TripAdvisor’s 15 Best Things to Do in Newton. There’s a short video, too, featuring many places you’ll recognize. Invite your downtown friends to take a trip up the Charles!
