The range (except for Mt. Hale) approximates the shape of a cross, with its main axis running north-south from North Twin to Bondcliff, and a shorter axis running west-east from Mount Garfield to Zeacliff. To the north of North Twin (and some smaller peaks such as The Nubble) lies the Ammonoosuc River valley. South of Bondcliff lies the valley of the East Branch of the Pemigewasset River. West of Garfield, a ridge joins the Twin Range to the Franconia Range (specifically, the north peak of Mount Lafayette). East of Zeacliff lies Zealand Notch. Mount Hale and the Sugarloafs form a second north-south ridge to the east of the main ridge and north of Zealand Mountain.
