Boston Basin

Boston Basin is widely considered the premier alpine climbing basecamp in North Cascades National Park. Tucked high above the Cascade River valley, this stunning alpine cirque sits directly beneath a concentration of the continent’s most famous rock ridges and steep glaciers. Serving as the primary launchpad for classic climbs like Forbidden Peak, Sahale, and the rugged Torment-Forbidden Traverse, our guided trips out of Boston Basin offer climbers an authentic, high-alpine camp experience coupled with immediate access to world-class, high-consequence mountain objectives.
