We don’t have Observatory Overnight trips scheduled for the winter 2025/2026 season. To find out about future Obs trips, please sign up for our email list or follow us on Facebook/Instagram. As an alternative, please consider our Mount Washington Winter Climb.

It’s hard to imagine a better outing in the White Mountains than an ascent of Mount Washington with an overnight in the Observatory. On the way up we can ascend the peak by any number of routes. The good news is that when you get to the summit, instead of turning around and wearily hiking back down, you’ll pry open the heavy door of the Observatory and soon find yourself transported to another world. The maximum group size is 9 people (plus guides) and these trips sell out fast. The price includes equipment rental, dinner & breakfast in the Mount Washington Observatory, plus two days of guiding on the mountain.

This trip is permitted by the NH Dept of Natural and Cultural Resources, Div. of Parks and Recreation, as well as the USDA White Mountain National Forest.

Course Information

You’ll sleep in a comfortable bunk and enjoy a nice dinner prepared by the Observatory staff, in addition to snacks and drinks. In the evening you will get a tour of the weather observation room and you’ll have the chance to speak with some of the observers and to learn about meteorology, local Mt. Washington weather and other important work that is done at this unique station. Sleep in until breakfast time, then by mid-morning we’ll begin the trek back down, either via the Lion Head winter route or possibly Boott Spur.

*** In the event that adverse weather conditions prevent the group from descending after the night at the Observatory, participants will be charged an additional fee per night. ***
