There are two major subsidiary peaks of Mt. Adams: Mount Sam Adams and Mount Quincy Adams, named after John Adams' cousin, Revolutionary leader Samuel Adams, and son, President John Quincy Adams, respectively, and two minor sub-peaks, Abigail Adams (named for John Adams' wife Abigail) and Adams 5. The northern side of the mountain ridge is located in Low and Burbank's Grant, and the end of Durand Ridge, and King Ravine, on the north side of Mount Adams are in the town of Randolph (formerly Durand). The entire south side of the mountain ridge is in Thompson and Meserve's Purchase.
The Appalachian Trail traverses the col between Mount Adams and Mount Sam Adams, on a path called "Gulfside Trail." The Randolph Mountain Club (RMC) maintains the trails and several huts and shelters high on Mount Adams' north side, including "The Perch," "Crag Camp," "The Log Cabin," and "Gray Knob." A large network of hiking and climbing paths lead south to the huts and ridges from several parking areas located on U.S. Highway 2.
