Take the planning and worry out of climbing Slesse!

Let our professional ACMG Guides at VMG plan and lead your climb. The NE Buttress of Slesse is deservedly a 50 classic in North America. Technically well within the scope of many rock climbers ability (5.9). The logistics of such a big route are daunting.

You will take 2.5 days to ascend and descend the route. VMG guides have climbed Slesse and understand the interconnectedness of variables presenting risk and how to mitigate those risks in order to guide it efficiently, and safely. Adding to the thrill of climbing Slesse is the experience of an open bivi on route!

Once on the summit you are only half way through the climb and your guide will then skillfully and safely navigate you down the mountain. Our Guides will plan an incredible trip that you will not forget!
