Route Assessment

All scales use five difficulty levels (easy, moderate, challenging, hard, extreme). The higher the number, the more demanding the tour. Each scale is tailored to a specific activity type, but the categories remain comparable. For example, a 3 in trail running is not the same as a 3 in hiking, but reflects a similar relative challenge within that category.

Hiking (Trekking)

LevelDescription
EasyWide paths, minimal elevation, no navigational challenges
ModerateClearly visible paths, occasional steep sections, easy navigation
ChallengingUnmarked trails, steep ascents, some off-trail hiking, good orientation skills needed
HardLonger stages with tricky navigation, stream crossings, scree and boulder sections
ExtremeHigh passes, long off-trail segments, alpine experience and weather resilience required

Trail Running

Level

Description

Easy

Runable trails, low elevation gain, no technical sections

Moderate

Mix of runable and steeper parts, basic trail conditions

Challenging

Technical terrain with scrambling, downhill skills required, occasional off-trail segments

Hard

Long, uneven trails, significant elevation gain, limited recovery sections, navigation may be difficult

Extreme

Exposed sections, off-trail running, high altitudes, physically intense and sustained segments

Mountaineering

Level

Description

Easy

Simple mountain tour without technical difficulties. Hiking paths, minor scrambling. No glacier contact, no exposure, no rope required.

Moderate

Steeper terrain, boulder fields, snowfields or glacier contact without crevasse danger. Poles, crampons or rope may help less experienced climbers. Partial self-navigation required, basic alpine orientation skills.

Challenging

Glacier travel with crevasse danger, steep snow or firn slopes, exposed sections, scrambling up to UIAA III. Excellent footing and basic rope handling skills required.

Hard

Mixed terrain (rock/snow/ice), long exposed sections, climbing up to UIAA IV, protection may be difficult (friends, nuts, slings). Prolonged exposure to fall hazards.

Extreme

Demanding alpine routes with technical climbing from UIAA V, high exposure, complex glaciers. Requires independent route-finding, advanced protection techniques, weather judgment, and solid alpine experience. Objective hazards (e.g., rockfall, avalanches) are part of the route.
