Tuckerman Ravine is a famed and classic route to the summit ridge of Mt Washington. It’s a challenging summer hike paralleling the upper reaches of the Cutler River at lower elevations and then ascends to rather exposed trail that crosses talus and winds around vertical rock. Although the lower trail may be accessible by snowshoe in winter the upper ravine portion requires specialized skills and equipment or may be closed all together. Be aware that conditions can change rapidly on Mt Washington bringing high winds and reduction of visibility to nearly zero. Check and heed weather reports before going and bring appropriate clothing for conditions. Bring extra food and water and be prepared for emergencies. Familiarize yourself with and observe regulations posted at the trailhead. Traction devices are advised for snowy or icy conditions. A parking permit is required at trailheads in the White Mountain National Forest.
