Lyon Mountain Professional Guide
Detailed Trail Description from our Guidebook
"The fire tower on the open rocky summit affords fantastic views of Chazy Lake below, and into Canada, Vermont, and the High Peaks region of the Adirondacks. Lyon Mountain is only 171 feet short of making the 4,000-footer list. It is a monadnock—a peak that stands alone—about 30 miles west of Plattsburgh, crowning the southwestern shore of Chazy Lake.
The original trail up Lyon Mountain was relatively short and steep, just under 2 miles but averaging 1,000 vertical feet per mile. A new trail was opened in 2009, which is more than a mile longer but much easier, with modern- day switchbacks and a moderate incline until it meets the old trail just below the summit. Your heart will pound as you scramble up the upper slopes. But it’s a worthwhile effort. The panorama from atop Lyon Mountain is the king of views in the northern Adirondacks if you like to look at mountains. You can see the highest peaks in both New York and Vermont from atop its fire tower as well as Montreal, Quebec, on a clear day."
