On Thursday morning, the park's superintendent heaped praise on the volunteer effort spearheaded by the Friends of Acadia.
Every Tuesday and Thursday, volunteers converge on the park to tackle a variety of tasks, allowing the park's staff to focus on other maintenance projects.
"People coming out and giving us their time and their talent and their sweat. It adds up to tens of thousands of dollars a year in labor that we give to the National Park Service. Probably best known for the work on the trails," David MacDonald, president of the friends group, said.
During a news conference on Thursday, Acadia National Park Superintendent Kevin Schneider said the excellent condition of Acadia's hiking trails and carriage roads is a credit to Friends of Acadia.
