The Wells River Rail Trail, which starts from the end of Industrial Park Road near Exit 17 of I-91 and heads east, passes through a great variety of habitats in a short distance. There is a wetland on one side for part of the way. The trail leads to a broad part of the  Wells River.

This section of the Cross Vermont Trail on the former railbed is a pleasant, gradual trail through stands of large trees with some sweeping views of Wells River, wetlands, and farms beyond. Wildlife viewing opportunities reward the quiet trail user. Together with the Boltonville Nature Trail and the Blue Mountain Nature Trail, there is a network of nearly four miles throughout the Wells River Conservation Area (including properties of the Allen Farm, State of Vermont, Town of Newbury, and Blue Mountain Union School.)

The Cross Vermont Trail is a project to build a multi-use, four-season path across the width of Vermont; following the Winooski River and Wells River valleys.
