The Ultimate Mount Washington Adventure

Overnight EduTrips allow you to fully experience the summit of Mount Washington by spending a night in our weather station at 6,288 feet above sea level. You’ll get to enjoy a full day of sightseeing and alpine adventure, then join our staff scientists for a hearty dinner in the comfort of our heated weather station.

Trip Format

Your adventure will begin at the base of the Mt. Washington Auto Road, where you’ll meet your trip leaders and load the snowcat. As you ascend the 8-mile road, you’ll take in the incredible scenery of Pinkham Notch and the Presidential Range while marveling at the power of a two-ton tracked vehicle plowing through massive snowdrifts.

When you reach the top you will have gained more than 3,500 feet of elevation, traveling from the temperate forest, through tree line, and into to the alpine zone—a rugged, otherworldly landscape of earth and sky. After unloading the snowcat you’ll head inside the weather station and warm up with a hot beverage and snack.

The rest of your visit will be planned around the mountain’s incredible weather, but will include:

  • Ample opportunity to experience subarctic-like conditions, which often include winds at, or above, hurricane force, remarkable icing, freezing temperatures, blowing snow, and more
  • A behind-the-scenes tour of the Mount Washington Observatory’s famous mountaintop weather station, where you’ll learn about the institution’s work and see the instruments used by Observatory scientists
  • A trip to the top of the instrument tower for a birds-eye view of the summit from the highest point on the mountain
  • A social hour and hearty dinner with the weather station staff
  • The opportunity to experience sunset and/or sunrise from the tallest peak in the Northeast
  • A night in our weather station on the summit of Mount Washington
  • Expert instruction in your chosen trip’s topic

Trips meet at 8:30am and generally arrive back at the base around 3:00pm the next day. Please note that the exact timing of your ascent and return will be determined by the weather, so participants should be prepared for schedule changes. The changes could be as minor as an earlier departure to avoid an approaching storm, or as major as a second night on the summit in the event of an extremely severe, unanticipated weather event. Safety trumps all other concerns, so please bring your sense of adventure and a willingness to go with the flow.

Dates & Topics

Implications of Global Climate Change (SOLD OUT)

Date: January 9-10, 2016 (Saturday-Sunday)
Instructor: Michelle Day, Scientist at the University of New Hampshire

Join Michelle to discuss this hot-button issue and learn about her experience as a research scientist drilling ice cores in Antarctica. Explore the evidence of past alterations in our planet's climate, possible causes of climate change today, and how past changes can help us understand the implications of climate change on our future.

Weather Basics (SOLD OUT)

Date: January 23-24, 2016 (Saturday-Sunday)
Instructor: Marsha Rich, Resource Agent for the American Meteorological Society

Washington.

Instructor: Mark Van Baalen, Geologist at Harvard University

Recent unexpected developments in the inexorable process of climate change have shown us that the Earth's response to a changing climate is far more complex than previously thought. The emerging field of Earth System Science tries to address all of these factors in a holistic manner, rather than simply as a physical or chemical question. Join geologist Mark Van Baalen in an assessment of what we know about climate, where we are likely headed, and how the Mount Washington Observatory fits into this picture.

Life, Work, and Environment atop Mount Washington (SOLD OUT)

This special trip departs from and returns to the employee parking lot at the base of the Mt. Washington Auto Road. The employee parking lot is located immediately north of the main entrance to the Auto Road. If you accidentally enter the main entrance of the Auto Road you will know you're in the wrong spot when you find yourself sitting at a locked gate. Go back to the road, take a left, drive a few hundred feet and turn left into the employee parking lot. You'll see your trip leaders and a Mount Washington Observatory vehicle.

The Mt. Washington Auto Road is located on NH Route 16 in Pinkham Notch, New Hampshire – 12 miles north of Jackson, NH, and 8 miles south of Gorham, NH. It is sometimes hard to find with GPS devices. Try "1 Mount Washington Auto Road, Gorham, NH" or simply enter "Mt Washington Auto Road" or "Glen House" in your GPS Attractions or Points of Interest page. However, remember that you are going to the employee parking lot, not the main entrance.

The GPS coordinates are: 44.28850 Lat., -71.22580 Long.

Travel Considerations

Extreme weather may occur at any time, and may delay a trip's descent. For this reason, we recommend that you remain flexible with your travel plans for the day or two after your trip. Weather-related changes are an inherent part of any true alpine adventure.

Area Lodging

For a list of area lodging options, visit our lodging partners.


Trip fees will be refunded for cancellations made at least 30 days before the trip date, less a $50 administrative fee. Cancellations less than 30 days but more than 14 days before the departure date will be credited at 50%. Cancellations made within 14 days of the trip date will result in forfeiture of the entire trip fee.

The safety of our guests and employees is of utmost importance, so trips may be cancelled due to extremely inclement weather. We will do our best to notify all participants of the cancellation in advance, but mountain weather is notoriously unpredictable, so we cannot guarantee advance notice. The decision to cancel a trip could be made on the morning of the trip, or even during the ascent. Please be prepared to have alternate overnight accommodations.
