Hiking difficulty scale
T - Tourist
Itineraries on small roads, mule tracks or easy paths, with clearly evident routes that do not pose uncertainties or problems of orientation. They generally take place below 2000 m and usually constitute access to mountain pastures or refuges. They require some knowledge of the mountain environment and physical preparation for walking.
E - Hiking
Routes that almost always turn on paths, or on traces of passage in various terrain (pastures, debris, stony ground), usually with signs. They require a certain sense of orientation, as well as a certain experience and knowledge of the mountainous territory, walking training, as well as appropriate footwear and equipment. Normally the difference in altitude is between 500 and 1000m.
EE - Expert hikers
Routes not always marked and which require a good ability to move on various mountain terrains. They can be paths or even faint traces that wind over rough or steep terrain, with steep and slippery slopes, scree and short snowfields that can be overcome without the use of climbing equipment. They need a good mountain experience, firm footing and good physical preparation. It is also necessary to have adequate equipment and equipment, as well as a good sense of direction. Normally the difference in height is greater than 1000m.
EEA - Expert hikers with mountaineering equipment
Routes that require the use of via ferrata equipment (lanyards, harness, heat sink, helmet, etc.). They can be equipped paths or real via ferratas. It is necessary to know how to use the technical equipment safely and have a certain habit of exposure and mountaineering terrain.
