Three Ponds is a 4.6 mile out and back trail located near Rumney, NH. The trail is primarily used for mountain biking.
Have done trail 2 times. Very enjoyable. Not difficult at all
Came here for a hike the day after some climbing. Some parts of the trail are indeed snowmobile paths, and were quite muddy. Not too much to see, pretty flat terrain, and the "ponds" were nothing special. You go by a stream for a bit of it, which was the pretties part.
This is a beautiful hike that's more like a walk through the woods. There are several trails so so make sure you follow the signs or you might end up on a snowmobile trail. The trail can be pretty muddy in a lot of places so wear the proper footwear.
