Every main stage's climbs and drops between samples 100 m apart
Keep in mind
In forests the model reads the treetops, so it reads high there

What
How hard the trail is, in three ways: the terrain, the climate in season and the length of the days
Scale
Easy to Hard, with the same thresholds for every trail; each takes its hardest measure
Keep in mind
It describes the trail, not how it will feel to you: that depends on your fitness, experience, pack and the weather you get

Demanding

  • SAC hiking scale

    This trail
    T2 (our estimate)
    Basis
    DOC grades the track intermediate in the Great Walks season: lake-shore forest, then "a challenging climb under impressive limestone bluffs" above the bushline to Luxmore Hut and an alpine ridge below Mount Luxmore (the summit side trip 1,472 m), down to Iris Burn on a formed, well-built track. Outside the season advanced and expert, with ice and snow. Mountain hiking on a good track over an alpine ridge (T2).
    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.

Wildlife

Nothing found

No dangerous animals or plants listed

We found no official source on dangerous animals or plants along this trail, so none is listed. That doesn't mean there are none: ask locally before you go.

Only official sources count here; none covered this trail's wildlife when we checked. Tumbleweed: drawn by us.
