Once known as Atherton Falls, the boiling whitewater of Wildcat Falls is one of the most popular destinations in Wildcat Falls Conservation Area. As such, there can be limited parking available, especially during the summer. If the parking lot is full it's worth coming back another time to not only see the falls, but also explore the walking/running/biking trails in this 87-acre patch of pine and hardwood forest.

Mill Pond is a fishable pond right off the Nashua River. It is dammed by the Mine Falls Dam, a small hydroelectric energy dam. Kayaks can be put in on a gravely shore, and hikers can border it on the south side via the Red Trail and the north side on the Mill Pond Trail. In the fall the trees change color and it's a peaceful area to enjoy.
