Scale

Demanding

  • SAC hiking scale

    This trail
    T3 (our estimate)
    Basis
    The association calls the trail an arduous trek in some areas but, on average, not terribly difficult terrain-wise; it climbs nearly 40 peaks, including the Presidential Range's Mount Eisenhower in the White Mountains, the steep bare rock of North Percy Peak and Dixville Notch's cliffs, and follows old farm lanes and logging roads in the north. Mountain hiking on steep, rocky ground in places (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.

Sleeping

Wild camping is restricted. In the White Mountain National Forest, south of Route 110, hikers may camp in the forest in most places, at least 200 feet from trails, under the Forest Service's rules; north of Route 110 only at the association's shelters and tent sites, the state campgrounds and private campgrounds. No campfires anywhere on the trail.

Blacklegged tick ModerateAmerican black bear Low

Blacklegged tick (deer tick)

Moderate danger

The CDC says ticks live in grassy, brushy or wooded areas; the blacklegged tick carries Lyme disease.

If you meet one

  • Walk in the center of trails
  • Use EPA-registered insect repellents containing DEET, picaridin, IR3535, Oil of Lemon Eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone
  • Treat boots, clothing and gear with permethrin
  • Check your body, clothing, gear and pets for ticks after being outdoors

Don't

  • Avoid wooded and brushy areas with high grass and leaf litter

Advice: US Centers for Disease Control and Prevention. Level: ours. Silhouette: Guillaume Dera (Ixodes ricinus), PhyloPic, public domain.

American black bear

Low danger

The White Mountain National Forest is home to a healthy American black bear population; normally shy and wary of humans, bears can become aggressive as they become habituated to human food.

If you meet one

  • Store your food, food containers, scented items (such as soap, lip balm, toothpaste) and trash properly
  • Use IGBC-certified bear-resistant canisters, or suspend food at least twelve feet above the ground and six feet from any object
  • Place sleeping tents at least 100 feet away from food storage and cooking areas
  • Give the bear(s) lots of room, 50 yards or more, and never surround it
  • Make lots of noise and look big

Don't

  • Never feed anything to a bear, or to any wildlife
  • Don't get between a sow (mom) and her cubs
  • Don't run; stand your ground or back away slowly
