The Trail Through Time is a two-mile bi-cultural heritage trail located mostly within the bounds of Nashoba Brook Conservation Land in Acton, Massachusetts. A kiosk stands at the main entrance, although two additional entrances, one with parking at Davis Road, and the other from Milldam Road, also provide access.

Forming a loop around one mile of Nashoba Brook, the trail passes through or accesses twelve sites where stone remains of structures from three periods of the land’s history still endure. Walking in either direction around the loop, visitors may be surprised by pre-historic, colonial, and industrial era stone ruins, all within a localized area.

While winding through diverse landscapes, the trail crosses the brook twice on rustic footbridges. The walking is easy along most of the trail as it meanders beside busy wetlands, through shady woodlands, and picks its way over a rocky section of an ancient Indian trail.

The trail is maintained by Acton’s Division of Natural Resources.
