85% of the area of the town is part of the White Mountain National Forest. Most residential development occurs in the southeastern portion of the town, along New Hampshire Route 16. Route 112, the Kancamagus Highway, runs east-west along the Swift River and is nearly entirely within the national forest. The former village of Passaconaway occupies a broad valley along the Kancamagus Highway in the northwestern part of the town. The area is now a national forest visitor attraction. Other place names within the town limits include Ferncroft, in the extreme southwest corner of town, and the former site of Paugus Mill, along the town's southern boundary.
