What is the MIDE System?

The MIDE (Método de Información de Excursiones) is a method to assess the difficulty and commitment of a walk. It creates a grading scale for the technical and physical difficulties of the routes, allowing them to be classified for better information.

Created by Alberto Paris Roche, it was designed as a tool for hikers to help choose the itinerary that best suits their experience, level of fitness and motivation. In this way, the MIDE is not only an information method but also a tool for the prevention of accidents in the hills and mountains, since the more information, the greater the safety!

The MIDE system is free to use and is designed to complement, in a unified way, the descriptions, evaluations and recommendations that each author considers appropriate.

The MIDE system is recommended by the Spanish Federation of Mountain and Climbing Sports (FEDME), by the Aragonese Federation of Mountaineering (FAM) and Civil Protection of the Government of Aragon, among other entities.


Evaluation information and reference information.

The information contained in the MIDE is of two kinds. One part of the system is an assessment of information from 1 to 5 points (from less to more) of four different aspects of difficulty : Risks in the natural environment, Route navigation, Difficulty of the terrain, and Physical effort required.

The other part of the system is reference information on each route: Duration of walk, Level of ascent, Level of descent, Total distance, and Type of route (Linear, circular, return by same route).


The grades are as follows.

MIDE riskRisks in the natural environment.

1. The environment is not without risks.

2. There is more than one risk factor.

3. There are several risk factors.

4. There are quite a few risk factors.

5. There are many risk factors.

nav iconRoute navigation.


1. Well-defined roads and crossings.

2. Paths or signs indicating continuity.

3. It requires the precise identification of geographical features and cardinal points.

4. Requires off-track navigation.

5. Navigation interrupted by obstacles to be skirted.

mide diffDifficulty of the terrain.


1. Walking on a smooth surface.

2. Walking on bridle paths.

3. Walking on staggered paths or uneven terrain.

4. During the walk it may be necessary to use the hands or jumps to maintain balance.

5. During the walk it may require the use of hands for progression.

mides effortPhysical effort required (carrying a light load).

 1. Up to 1 h of effective walking.

2. Between 1 h and 3 h of effective walking.

3. Between 3 h and 6 h of effective walking and/or short sections of steep ascent.

4. Between 6 h and 10 h of effective walking and/or longer sections of steep ascent.

5. More than 10 hours of effective walking and/or continuous sections of steep ascent.
