  • SAC hiking scale

    This trail
    T4 (our estimate)
    Basis
    carrosdefoc.com calls it "a high-mountain route" on "granite blocks, landslides, and paths", without marking of its own, where "using a map is an essential requirement", crossing passes up to the Coll de Contraix (2,745 m) with 9,200 m of climbing; "in bad weather conditions it can get really complicated". Pathless boulder fields and steep scree passes: demanding alpine hiking (T4).
    Scale
    The Swiss Alpine Club's hiking scale, from T1 (easy) to T6 (very hard)
    Why
    Trails rate difficulty in many local scales, or only in words; we translate each into this one so trails compare
    Keep in mind
    An estimate: how hard a trail feels depends on your fitness, experience, pack and the weather
    T1 · Hiking
    Well-made paths, mostly flat or gently sloping. No risk of falling; trainers are enough.
    T2 · Mountain hiking
    A continuous path, steep in places, where a fall can't be ruled out. Be sure-footed; wear hiking boots.
    T3 · Demanding mountain hiking
    The path is not always visible; exposed spots may have chains or ropes, and you may need your hands for balance.
    T4 · Alpine hiking
    Often no path. Hands are needed in places, terrain is exposed, and there can be easy snowfields.
    T5 · Demanding alpine hiking
    Mostly pathless, with easy climbing and exposed, demanding terrain. Needs alpine experience.
    T6 · Difficult alpine hiking
    Pathless, very exposed, with climbing and glaciers. For experienced mountaineers only.

Totals and averages count the main stages only. Distances are ours, measured on the OpenStreetMap map line between the stage ends: no source publishes them. ≈ marks our estimates where the source gives no figure: ascent and descent and heights from the terrain model (Copernicus DEM, 30 m grid, sampled every 100 m), to the nearest 10 m.

High
A bite of a species it calls common can be life-threatening within hours

It warns of attacks or serious harm, or places the trail in a risk area for tick-borne encephalitis

Asp viper Low

Asp viper

Low danger

The asp viper lives in northern Catalonia among rocks and shrubs, in alpine forest, gullies, stone walls and by streams, in the national park up to about 2,300 m. Its venom is the most active of Spain's vipers, but it is fairly docile and usually avoids people.

If you meet one

  • After a bite, keep the person calm and get them to medical care without running or cycling
  • Keep the bitten limb still, without raising it
  • Take off rings, bracelets and anything tight near the bite
  • Disinfect the wound and cool it moderately

Don't

  • Apply a tourniquet
  • Put ice directly on the skin
  • Cut or suck the wound
  • Give alcohol, sedatives or home remedies
