From tour planning to route selection, terrain management, avalanche safety, and gear knowledge, your guide’s expertise and backcountry experience will ensure you have an unforgettable ski touring adventure. It doesn’t matter your skill level, whether you’ve never backcountry skied or you’re seasoned on the slopes, skiing with a guide has its advantages. Your techniques will sharpen, you’ll learn how to navigate terrain safely, make smart decisions, and most of all, you’ll remain safe in unfamiliar terrain.

Mitigating avalanche risk is paramount for any excursion in the backcountry — that’s why it’s best to tour with a guide! Rest assured, your guide will set objectives that are attainable for the weather conditions on that particular day. Of course, inclement weather can always get in the way of backcountry skiing, but your guide will know the best course of action to take if the weather takes a turn.

On the rare occasion of truly bad weather, your guide will present you with suitable, safe alternatives. The most common practice is to move to a nearby location if it exists, or to reschedule your backcountry ski tour to a more favorable day.

If backcountry skiing is not possible on your scheduled day and no options presented are viable, you will be issued a full refund.

We highly recommended that you cover all your bases with emergency medical insurance. With medical insurance, if you have an accident or medical emergency on or off the mountain, you’ll avoid paying out of pocket for costly expenses. This covers everything from hospital treatments to emergency air transportation and more.

If you need assistance selecting the right insurance for your group, let us know and we will be happy to help!

The most convenient way to get to Mammoth Lakes is to fly into Mammoth Yosemite Airport (MMH). Los Angeles, Burbank, Denver and San Francisco offer direct flights. Another option is to fly into Reno-Tahoe International Airport (RNO) which is only 2.5 hours away from Mammoth Lakes. From there you can rent a car or take a shuttle.

Once you and your guide agree on the details of your itinerary, your guide will suggest the best place to meet, whether that’s at the guide shop or a predetermined location and from there you will go through a quick gear check as well as a quick avalanche beacon refresher. From there, the group will head out to the tour, where we will quickly get into touring mode and start stretching the legs for the uphill ascent.
