Warren sits at the base of Mount Moosilauke in Grafton County, one of the prominent peaks along the Appalachian Trail's approach to the White Mountains. The town's small village includes a notable Redstone rocket displayed as a local landmark.

Mount Moosilauke draws hikers throughout the year, while the Baker River offers fishing and paddling closer to the village. Warren's small commercial center serves the surrounding rural community and passing hikers.

Housing in Warren remains affordable, drawing outdoor enthusiasts, hikers, and families who want White Mountains access at a lower cost than resort towns further north.
