The Adirondack mountains and boulders of northeastern New York, already known as a destination for rock climbers, also offer some of the most challenging ice climbing routes on the East Coast. At six million acres, hikers, paddlers, skiers and mountaineers can access even the most remote areas of the Adirondack Park. For rock climbers, some of the best routes can be found deep in the wilderness or right off the highway. Many of these climbing and bouldering locations are also used for ice climbing and ice bouldering.
