The Post Mills Nature Area (PMNA) is a 104-acre parcel owned by the Town of Thetford and covered by a conservation easement held by the Upper Valley Land Trust. The PMNA abuts the Upper Valley Regional Landfill (which is closed and capped) and was acquired through an agreement with the State of Vermont, the Upper Valley Regional Landfill Corporation, and the Town of Thetford in August 2000. The easement provides for a watershed protection area and protects natural communities and wildlife habitats while providing public access for benign, non-motorized recreation and educational uses.

The Post Mills Nature Area is located on VT-113, approximately 4 miles north of Town Hall. The access is on the right as you enter Post Mills from Thetford Center and is the old landfill site just before “Sunshine Corner “and the Malmquist Mill.

No formal trails exist on PMNA, however, there is a clear path that runs through the fields and there are many logging roads throughout the forested area. The path starts after the metal gate and leads across the open fields. At the end of the field, it crosses a small stream into a smaller field. There are trail branches that lead into the pine forest along old logging roads and eventually cross into private property. Non-motorized recreation including walking, snowshoeing, skiing, and bicycling are allowed as well as hunting and fishing in small non-commercial groups. Snowmobiles and all-terrain vehicles are not allowed, nor are camping or fires. Dogs must be leashed. The property is intended to be enjoyed short term and with very low impact. All uses are subject to available parking.
