The Avalanche Pass hiking trail is closed to the public due to a landslide. This closure impacts several routes, including the passage south to Lake Colden from the Adirondak Loj and loops routes over Algonquin, Marcy, and Colden.
Another slide was reported on the southeast side of Mount Colden into Feldspar Bog/Lake Arnold Trail. The Lake Arnold Trail is open and passable.
The public is advised to avoid any loops around Algonquin and Colden. Any hike that goes through Avalanche Pass is not viable.
The Marcy-Skylight-Gray loop is not viable through Avalanche Pass and will require extra care through the Lake Arnold Pass. Marcy, Algonquin, Colden can all be climbed as out-and-backs.
Trail work to repair damage from the landslides is underway as of the summer of 2026.
