Ski Touring Explained
What Ski Touring Actually Is
Ski touring — referred to as randonnée or Alpintouring in much of Europe — is the practice of ascending a mountain under your own power with skis on your feet, then descending on those same skis. It is the oldest form of skiing, predating lifts by millennia, and it has experienced a significant resurgence since the early 2010s as both a fitness pursuit and an access tool for backcountry terrain that lift networks cannot reach.
The key enabling technology is the climbing skin — a strip of directional mohair or synthetic fabric that attaches to the base of the ski and allows forward gliding while blocking backward slip. With skins on, a skier can ascend slopes of up to roughly 30 degrees with reasonable efficiency. Modern adhesive skins attach to the base using a skin-safe glue that grips the ski without damaging it and can be peeled off and reapplied hundreds of times before the glue degrades.
Touring bindings are the second essential component. Unlike alpine bindings, which clamp the boot heel rigidly for downhill control, touring bindings allow the heel to lift freely during ascent, mimicking the walking movement of the foot. When the skier reaches the summit or transition point, the binding locks down into alpine mode for the descent. This heel-lock mechanism distinguishes genuine touring from purely off-piste skiing on resort equipment.
Touring Binding Systems
Several competing binding systems now dominate the touring market, broadly divided into frame bindings and tech bindings (also called pin bindings or Dynafit-style after the brand that invented the system in the 1980s).
Frame bindings clamp the boot through a frame similar to an alpine binding and allow the entire frame to pivot at the toe. They are heavier but compatible with stiff alpine-style boots and offer alpine-comparable downhill retention and control. They suit skiers who prioritise the descent — particularly those tackling technical or steep terrain — but the weight penalty is significant on long approaches.
Tech or pin bindings connect to the boot through two metal pins that insert into holes drilled into the toe of a tech-compatible boot. The system is dramatically lighter — a complete pin binding can weigh under 200 grams per ski — and the heel lifts completely freely with no frame drag. The trade-off is a reduced retention range compared to alpine bindings, and tech bindings require specific boots with pinhole fittings. Every boot manufactured for touring now includes these holes, but older alpine boots are not compatible.
Hybrid systems attempt to bridge the gap by offering pin-binding touring efficiency and a heel piece that locks down with alpine-grade lateral resistance. Bindings like the Salomon Shift and the Marker Duke PT have made significant inroads with advanced skiers who want technical off-piste capability with manageable weight.
Ski Touring Boots
Touring boots are a study in compromise. A stiffer boot provides better power transmission during the descent and more edge control on hard snow. A lighter, more flexible boot walks and climbs more naturally and conserves energy over long ascents. The ideal balance depends entirely on the type of touring planned.
Race-oriented boots like the Scarpa Alien series weigh under a kilogram per boot and are designed for ski mountaineering competition — fast ascents, short technical descents. They are not appropriate for a first-timer attempting a classic Alpine tour with significant vertical. Freeride touring boots at the other end of the spectrum, such as the La Sportiva Syntech or the Hagan Boost, are stiff enough for genuine off-piste skiing but heavy enough that a six-hour ascent will punish the unprepared.
Walk mode on a touring boot unlocks the cuff from the lower shell, allowing the ankle to flex forward during the stride. A boot with a generous cuff rotation angle — 60 degrees or more — walks considerably more naturally than one with limited movement. This matters enormously on steep, sustained ascents where a restricted ankle forces the skier into an exhausting, unnatural gait.
The Ascent: Technique and Route Selection
Skinning uphill efficiently requires a different mental model from lift-accessed skiing. The goal is to maintain a steady aerobic pace that can be sustained for hours, not to go as fast as possible. Heart rate should stay in a conversational zone — the classic test is whether you can speak in full sentences without gasping. Exceeding this threshold builds lactic acid in the legs and forces rest stops that extend the total time on the mountain.
Route selection on the ascent involves reading the slope for avalanche terrain, finding the most efficient gradient, and choosing a line that avoids breakable crust or deep unconsolidated layers that will tire the legs. The classic touring approach is to switchback diagonally across a slope, keeping the angle manageable while gaining elevation. Kick turns — pivoting 180 degrees at the end of each traverse — are the fundamental technique for reversing direction on steep ground with skis on, and they feel unnatural until practised on flat ground.
The transition from uphill to downhill mode — removing skins, adjusting binding heel pieces, changing boot cuff settings, adding layers if temperature allows — takes five to ten minutes of practiced routine and significantly longer for beginners. Cold, wind, and fatigue make transitions harder; arriving at the top in good condition means pacing the ascent properly, not sprinting to the col and arriving depleted.
Avalanche Safety as a Non-Negotiable
Ski touring takes place almost entirely in avalanche terrain. This is not a risk to be managed as a footnote — it is the central safety consideration of the discipline. The standard touring safety kit is a transceiver (avalanche beacon), probe, and shovel. Every member of the party must carry all three, know how to use them, and have taken an avalanche safety course from a certified provider such as AIARE in North America or a guide-school equivalent in Europe.
Understanding the European Avalanche Danger Scale (1 to 5) is the entry point, not the conclusion. Danger 3 (Considerable) means avalanches can release on moderately steep slopes and the consequences of a poor decision can be fatal. Most touring accidents occur at danger levels 3 and below, not at 4 or 5, because strong skiers continue touring when they should not. Checking the daily avalanche bulletin from the relevant national service — Lawinenwarndienst in Austria, MeteoSchweiz in Switzerland, ARAN in the Catalan Pyrenees, avalanche.org in North America — before every tour is obligatory.
Where to Begin
The entry point for ski touring is a guided day tour on moderate terrain with a qualified mountain guide. Many Alpine resorts offer guided tours on the mountains surrounding the resort network, departing from the top lift. This removes the navigation challenge and allows a first-timer to focus on the technique of skinning, transition, and avalanche awareness in a controlled setting.
Classic beginner-friendly touring routes include the tour above Arosa in Switzerland, the Fanes plateau above Cortina d'Ampezzo, and the skin tracks above Jackson Hole in Wyoming. In Japan, touring around Furano and Niseko has become increasingly accessible, though language barriers with official avalanche information require local guide knowledge.
