The Yellow Trail is a popular short loop on the northern end of the Blackall Family Preserve and Ballou Farm Preserve. It is most easily accessed via the Old West Wrentham Trailhead, but can also be accessed from the Powerline Trailhead and linked with other trails here to extend your hike. While this is a generally easy trail through the woods, it can get quite muddy in the spring and after rain so prepare accordingly.
