About National Forest Development 104 Pack

National Forest Development 104 Pack is a 18.2 km hiking route in Idaho, United States. It climbs roughly 879 m (2,884 ft) along the way, topping out at 2,354 m (7,723 ft). Most people take around 5 hr 13 min at a comfortable pace, plus stops. It rewards preparation. Strong legs, an early start and a weather window all make a large difference here.

The woodland changes character with the seasons, at its best when the canopy turns. This is mountain terrain, and the scale of the surroundings is the reason to come.

Start and finish are in different places, which means public transport or a second car is part of the planning. It is not consistently waymarked, so carry a map or a downloaded track rather than relying on signs.

The high sections hold snow long after the valleys are green, which keeps the usable season to high summer.

In short, National Forest Development 104 Pack suits fit hikers with a habit of long days and an eye on the forecast. Dog access is not formally recorded here, so check locally before bringing one.

The route in detail

The route is normally walked in the direction described below. The first third does most of the climbing, so settle into a slow rhythm early rather than trying to hold a flat-ground pace. The steepest pitch runs at roughly 44 percent, short but enough to slow most people to a crawl. The upper section is where the route earns its reputation, and it is also where weather changes fastest. Because the finish is away from the start, check return transport before committing to the second half.

Tips from the trail

  • Start at first light. A long day is far more pleasant when you are not racing the sunset on the descent.
  • Aim for july to september for the most reliable conditions.
  • Download the track to your phone before you leave. Signal is not guaranteed.
  • Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.

Warnings

  • This route is long and sustained. Turn back early rather than late if the weather closes in.
  • Some sections are steep enough to be awkward in the wet, particularly on the way down.
  • At this altitude the weather can turn in under an hour, and temperatures drop fast once cloud arrives.
  • Outside the main season expect snow, ice or closed access on the higher sections.

Safety

Emergency services in United States are reached on 911. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage in the upper sections is patchy at best, so do not count on being able to call for help from the summit. If the weather deteriorates, descending the way you came is almost always the safer option.

What to bring

  • Comfortable, broken-in hiking shoes or boots
  • Weatherproof jacket
  • At least 1.5 litres of water
  • Trekking poles for the descent
  • Offline map and compass
  • Head torch and spare battery
  • Extra warm layer
  • Sun hat, sunglasses and high-factor sun cream
  • Microspikes if you are walking at the edges of the season

Photography

Shoot the first hour after sunrise from the higher ground: the low angle picks out every ridge and the valleys still hold mist. Take the shot on the way out. Conditions rarely improve by the time you come back past. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
