Randolph's geography is mountainous. The south side of the town includes the northern slopes of the Presidentials. The north side of the town includes four main mountains: Mount Crescent, Black Crescent Mountain, Mount Randolph and Pond Hill. Dividing the northerly slopes from the southerly slopes is US Route 2. There are no trails maintained to the top of Black Crescent Mountain or Pond Hill. The highest point in Randolph is on the town's southern border, atop a knob on Howker Ridge, a spur of Mount Madison.
