If you’re looking for a peaceful change of scenery and a chance to get a little exercise, check out Babes in the Woods, a free Tuesday drop in activity at the Middlesex Fells Reservation in Stoneham. Tomorrow’s event (June 12, 10 – 11:30am) will involve stroller-friendly loops around Bellevue Pond. Next Tuesday’s event will be a more challenging (but not strenuous) hike, suitable for slings, packs, or rugged terrain strollers.
