Maine Coast Heritage Trust’s Aldermere Farm, 20 Russell Avenue in Rockport, will offer farm tours every Friday at 10 a.m. through August (except August 2), beginning on Friday, June 28. The visitor center at the farm will open on July 1. The center houses a gift shop/beef store staffed by volunteers who can share the 200-year history of the farm and orient visitors to its trails and sites, where they can view Aldermere’s Belted Galloway herd. Sales from the store support agricultural programming at the farm. Store hours July through September are 10 a.m. to 1 p.m. Monday through Friday and 1 to 4 p.m. Saturdays. To volunteer, email Joelle Albury at jalbury@mcht.org or call 236-2739.
