Trip details

57hours is committed to providing safe outdoor adventure experiences. We require all guides using our platform to have a COVID-19 safety plan and to make the details of that plan accessible to travelers. In most cases, group sizes will be reduced, guides will avoid overcrowded locations, and other safety measures will be met depending on the location and activity.

We also expect clients to respect local regulations and take measures to protect themselves, guides and the communities they’re travelling to. For more information on COVID-19 measures in Big Sky and Yellowstone, please refer to the Montana Office of Tourism.

Please contact us if you have any questions or require further information. We are happy to provide you with the most up-to-date information!

In order to enjoy this backcountry adventure, you need to have a moderate level of fitness. You will be on your feet for a full day. While there is terrain for all skill levels in Yellowstone, you will need to manage controlled descents in variable conditions. All participants should feel comfortable on blue level resort runs and be able to carry a loaded daypack while skinning up variable degrees of terrain.

For the enjoyment and safety of everyone involved, participants must be approved to participate in advanced backcountry skiing tours either through a previous trip with the guiding service or through recommendations.

Backcountry skiing isn’t just for pros looking for the ultimate thrill ride, it’s also beginner friendly, meaning anyone with blue level resort experience can have fun in the backcountry. If you’ve never backcountry skied before, heading out with a guide is your best bet. They’ll take care of the planning, introduce you to the basics, like skinning uphill, and teach you how to manage the terrain. They also have the experience and avalanche training to keep you safe.
