Nachfolgende Ausführungen sind aus der offiziellen „Classificazione dei percorsi in base alla difficoltà in ambito escursionistico e cicloescursionistico“ des Club Alpino Italiano entnommen, die am 20. November 2021 vom Comitato Centrale mit Delibera Nr. 89/2021 approbiert wurde. Das Dokument definiert die Grundlagen für die landesweit einheitliche Einstufung von Wander‑, Berg‑ und Ferratawegen im Zuständigkeitsbereich des CAI.
Tourists: T
Routes along lanes, mule tracks or easy paths. These are generally short, clear, well-marked trails with no significant orientation difficulties. Elevations gains are usually less than 500m. These hikes do not require any particular experience or physical preparation.
Hikers: E
Routes that generally follow trails or tracks over varied terrain (fields, loose rock, scree), usually signposted. They require a basic sense of direction, some hiking experience, familiarity with mountain terrain, good walking fitness, and proper footwear and equipment. Elevation gain usually ranges between 500 and 1000m.
Experienced hikers: EE
Routes that are not always marked and that require good ability to navigate various mountain terrains. They may be trails or faint paths on rugged or steep terrain, with steep and slippery slopes, scree and short snowfields that can be crossed without the use of mountaineering gear. These routes require good mountain experience, surefootedness and good physical fitness. Proper gear and equipment are also necessary, as well as good orientation skills. Elevation gains are usually over 1000m.
Experienced hikers with mountaineering equipment: EEA
Routes that require the use of via ferrata equipment (lanyard, harness, shock absorber, helmet etc.). These may be equipped trails or actual via ferrata routes. It is essential to know how to safely use the technical gear and to be accustomed to exposure and alpine terrain.
