Bettina Abe, a long-time Acton trail volunteer and retired member of Acton’s Conservation Division, will lead a brisk hike along the Nashoba Brook Trail, with stops at the stone chamber and Native American ceremonial sites. Trail conditions can be rocky, uneven, and often wet, and thus participation is limited. Registrants will receive a detailed email several days before the walk.

Limited to 20, ages 17 and up.

In person only—All programs are free but require registration here.
