An exclusive opportunity to spend the night on the highest summit in the Northeast.

Situated at the intersection of three major storm tracks which affect the northern Appalachian Range, and rising from the surrounding lowlands for much of its 6,288 feet, Mount Washington is known for its extreme weather conditions. Mount Washington is the highest peak in the Northeast and the conditions above timberline are as serious as any mountain in North America. As we ascend we will discuss general mountaineering skills, winter navigation and we will be able to practice basic crampon, ice axe skills and self arrest techniques. No previous mountaineering experience is required to register. However, participants should be physically prepared and well equipped for a rigorous all day experience. We will meet at IMCS at 7:00 a.m. for a gear check and to get fitted for mountaineering boots, crampons and ice axe.

At the summit, you will receive an educational tour of the Observatory with their experts, and have the unique opportunity to watch the sunset and sunrise from the warmth of the summit building.

Includes tour of the summit building / observatory, hot dinner, and overnight accommodations.

Although you have most of the day to make the summit, this is still a physically demanding hike. Please call with any questions.
