The Hopkinton Trails Club will host a group walk at Rockwood Meadows on Sunday, Jan. 12, at 1 p.m. These trails head into the Peppercorn Hill conservation area and offer a number of options for loop walks. The leaders will decide what’s best based upon the weather and the group’s interest. Participants will meet at the parking lot just after School Street crosses into Upton and becomes East Street.
