The following statements are based on the definitions published by SAT (Società degli Alpinisti Tridentini) on its website. These are aligned with the set of rules adopted by the Club Alpino Italiano in 2021 for classifying hiking, mountain, and cycle‑hiking routes according to their level of difficulty (Resolution No. 89/2021). Following represents the original version as provided by SAT.
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.
