Course Information

Mt. Washington is known as the Home of the World’s Worst Weather, and still holds the world record for the highest windspeed ever witnessed by man, a mind boggling 231 mph. During the winter months, the wind speed on the summit tops 70 mph at least once every three days, and it’s not uncommon for climbers to encounter temperatures of -30F and below. You’ll be above treeline for about half of the ascent, which for many is their first experience with a true alpine environment.

The alpine conditions, combined with Mt. Washington’s accessibility, allow you to gain invaluable winter survival experience…without having to travel to the Rockies, Cascades or Alaska. The SMG guides have hundreds of Mt. Washington ascents under their belts, and this deep experience level and local knowledge will allow you to push yourself higher and farther than you might have thought possible. Most of our guides are members of the Mountain Rescue Service, so you’ll be making your ascent with someone who has conducted numerous rescues on the mountain. Simply put, you could not be in better hands.

In addition to potentially bagging one of the most iconic summits in the lower 48, your guide will work with you on the skills you’ll need to become a competent mountaineer. Here’s a partial list of topics:

  • Training
  • Gear and clothing selection
  • Preparation and packing up
  • White-out navigation and route finding
  • Avalanche awareness
  • Crampon technique
  • Ice axe technique including self arrest
  • Pacing
  • Frost bite and hypothermia awareness
  • Proper hydration and food intake
  • Descending and down-climbing, including glissading


No prior experience is required, but the ascent is 4.1 miles and 4250 vertical feet, so participants should be physically fit and ready to trudge uphill with a sizable pack for four or five hours. If you are interested, we can help you with a training program to get prepared for the ascent.


8 hours, approximately five hours up, and three hours down.

Equipment & Clothing

SMG will supply you with mountaineering boots, crampons, and ice axe. Please contact us for a copy of our winter gear list. While you are responsible for your own clothing, we do have some items for rent, so contact us if you are short on gear – we will help you to get the proper kit together.

When & Where

Your day will start at the SMG office in Intervale NH at 7am. We can get you outfitted with your gear and clothing then, or you can stop by the afternoon or evening before if you are already in town.
