Donaldson Mountain, also called Mount Donaldson, is the 33rd-highest of the 46 Adirondack High Peaks with an elevation of 4140'. It is the middle peak in the Seward Range, with Seward Mountain to the northeast and Mount Emmons to the south.
Be prepared for a long day if you choose to climb Donaldson Mountain. It takes experienced hikers approximately 5 hours to summit, and is not recommended for inexperienced hikers or children. When climbed in combination with Seward and Emmons, the total distance covered is almost 18 miles.
The primary trailhead is located on Corey's Road in Tupper Lake. The route from this trailhead begins on a well-used trail, continues on an old woods road, and eventually concludes on the Calkins Brook herd path. Brilliant views are afforded from the lardge ledge on Donaldson's summit, and the herd path continues from there to Emmons' summit.
Donaldson was named for Alfred Lee Donaldson, author of A History of the Adirondacks, and was the first Adirondack peak to be named during the twentieth century.
