Circle CG Farm Campground

131 North Main Street, Bellingham, MA 02019

Just an hour outside Boston, this 30-acre spot keeps kids busy from breakfast to bedtime — think panning for gems, cannonballs in the pool, and s'mores around the evening fire. With 150 sites and the rare bonus of staying open all four seasons, it's as good for an October foliage weekend as a July heat wave.
