Mountaineering in the USA & Canada

This covers the trails that need a helmet, the routes where you turn around for weather, and the summits where altitude matters as much as the route. Our coverage skews toward Class 2/3 — the line between hiking and technical climbing — because that's where most readers actually go.

If you're after technical alpine, try AMGA-certified guides. We cover the routes you can do with hiking-plus-attention.
