Difficulty
- 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

SAC hiking scale
- This trail
- T3 (our estimate)
- Basis
- The Green Mountain Club calls the trail beautiful and challenging, with rocks, roots, mud and steep climbs, especially in the northern half, over all five of Vermont's 4,000-foot peaks including Mount Mansfield; a seasoned backpacker may walk fewer miles a day than on other long-distance trails. Mountain hiking on steep, rocky and rooty ground, with the hands needed on the steepest slabs of the north (T3).
- 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.
