Understanding Hiking Trail Difficulties: The SAC Scale

The SAC Hiking Scale is the standard in all German-speaking countries denoting the difficulty of all paths, hiking ways, and trails. Developed by the Swiss Alpine Club, it takes surface, gradients, exposure, experience and gear required, and safety precautions into account.

Grade Trail Type Description
T1Hiking TrailsWell-cleared trails with no major challenges. Compact surface, gentle gradients, no risk of falling.
T2Mountaineering TrailsWell-marked trails with occasional steep sections. Slight risk of falling.
T3Demanding Mountaineering TrailsTrails may be steep and exposed. Chains or ropes are often provided. Higher risk of falling.
T4Alpine Hiking TrailsTrails may be unmarked. Includes gravel, glaciers, or steep terrain. Constant exposure risk.
T5Demanding Alpine Hiking TrailsNo clear path. Includes rocky slopes, glaciers, and technically challenging terrain. Gear like ropes/ice axe may be needed.
T6Advanced Alpine Hiking TrailsUnmarked and includes climbing (UIAA grade II). Very steep, icy, or glacial. High risk. Advanced alpine gear required.

Difficulty Levels of Mountain Trails

The SAC Hiking Scale evaluates the nature of the terrain, the exposure of the trail, and the technical equipment and experience required. It is the standard across Switzerland, Germany, and Austria.

  • T1: Easy valley trail. Flat terrain, no falling risk. Normal shoes sufficient.
  • T2: Slightly steeper mountain trail. Some surefootedness required. Trekking shoes recommended.
  • T3: Steeper, exposed paths. Ropes or chains may be present. Good orientation and hiking experience needed.
  • T4: Alpine trails with exposure and technical demands. May include snowfields and unmarked paths.
  • T5: Demanding alpine terrain, glaciers, scree, rope/axe may be required.
  • T6: Technical alpine climbs, glacier crossings, rope use. High-risk, expert-only.
