I've been mountaineering for years, and when I first strapped skins on my skis and began the transition from descent-only skier to ski mountaineer, I underestimated how much I had to learn. The fitness translated immediately โ my uphill endurance was there. The technical skills did not. I struggled with kick turns, fought with transitions that took forever, and discovered that efficient skinning technique is a completely different skill from hiking or climbing. What I'm sharing here is the distilled learning from several seasons of ski mountaineering practice, focused on what would have helped me most when I started.
The Skin Track: Efficient Uphill Travel
The skin track is your uphill travel path, and its quality determines your efficiency for the entire tour. Good skin tracks are laid out in switchbacks that allow you to maintain a climbing angle while managing energy expenditure. The steepness of a ski mountaineering skin track is typically 15-25 degrees โ steep enough to make meaningful elevation gain, shallow enough to maintain for hours without the extreme exertion of bootpacking.
Skin technique begins with body position. Your weight should be centered over the balls of your feet, with a slight forward lean. Your poles plant ahead and slightly to the side, providing support and rhythm. The pace is steady and sustainable โ a cadence of roughly one pole plant per second, moving continuously rather than stopping to rest. The goal is to maintain a moderate heart rate throughout, which for most climbers means talking comfortably while ascending.
Skin grip comes from the mohair/nylon mix of modern climbing skins, but grip is dramatically affected by snow conditions. Cold, dry snow provides excellent grip. Warm, wet snow reduces grip significantly as moisture fills the skin fiber. Icy conditions can be slippery even with fresh skins โ in icy conditions, boot crampons (hiked, not skied) may be necessary. Carrying skin-specific grip wax for cold conditions is common practice among serious ski mountaineers.
Skin track etiquette: skin up the fall line on established tracks (not in the middle of the track where your edges could damage the skins), yield to faster parties behind you by stepping aside, and never skin directly below a group that's descending โ the fall line is the danger zone.
The Kick Turn
The kick turn is the fundamental ski mountaineering maneuver โ a pivot that allows you to reverse direction on steep terrain without making a U-turn. It's the technique I struggled with most when learning, and it's still awkward on steep or firm snow.
The standard kick turn: As you approach your turn point, shift your weight to your uphill ski. Lift your downhill ski and swing it 180 degrees so it points back up the hill, with the tail close to your standing ski. Plant your pole firmly to support balance during the swing. Once the turned ski is stable, bring your standing ski alongside it and adjust to the new direction. The entire maneuver should take 3-5 seconds once practiced.
On steeper terrain, the "Australian" kick turn provides more stability: instead of swinging the ski in a wide arc, you lift and flip the ski more vertically, keeping the swing compact. This is more awkward initially but becomes more controlled on steep slopes.
The most common error is failing to commit weight to the standing ski during the swing โ keeping weight on the ski you're trying to move makes the turn nearly impossible. Practice kick turns on gentle terrain until the motion is automatic before attempting them on steep ground.
Uphill and Downhill Technique
Ski mountaineering demands technical skill in both directions. For uphill travel, the herringbone technique (ski tails spread, tips pointed outward in a V-shape) provides additional grip on steeper terrain where skinning alone is insufficient. Herringbone requires good leg strength and ankle flexibility, and it's exhausting over long distances โ use it for short steep sections, not extended climbs.
Downhill technique for ski mountaineering differs from resort skiing because you're likely in variable snow conditions, potentially in avalanche terrain, and without the safety infrastructure of managed runs. The fundamentals are the same, but the stakes are higher. In variable snow, maintain speed control appropriate to visibility and snow quality. In powder, a wider stance improves float. In crud, speed provides momentum that helps the skis push through_variable surface. In wind crust or hardpack, sharp edges and careful speed management are essential.
Transition Efficiency
The transition between touring mode (skins on, heels free) and descent mode (skins off, heels locked) is the key skill that determines how many laps you can do in a day. A transition that takes 5 minutes instead of 2 minutes means you've lost 30 minutes over a 5-transition day โ meaningful in short winter daylight windows.
The ski-to-skin transition (beginning the ascent): Remove your skis if you weren't skinning from the trailhead. Peel off the skins โ modern skins release easily from the tip and tail. Stow skins in your pack or in the designated skin pocket on your touring bindings. Switch your bindings from descent to touring mode (heel lifted). Put on your climbing skins (attach tip first, then tail), adjust for tension.
The skin-to-ski transition (beginning the descent): Find a safe flat spot to transition. Remove climbing skins, fold them with sticky side together, stow in pack. Switch bindings from touring to descent mode. Apply descent skins (skins removed for touring, crampons may be needed). Do a quick safety check: beacon on and sending, poles adjusted, goggles in place.
Gear Considerations
Ski mountaineering requires specialized gear: touring skis (lighter than resort skis, with metal edges for hard snow), touring bindings (pin-style bindings that allow heel lift for climbing), climbing skins (mohair/nylon mix that grip in one direction), ski crampons (metal plates that attach to skis for icy climbing), and boots with both tour and descent modes.
