Finest Time to Hike

Like many mountainous and northern latitude thru-hikes, the Idaho Centennial Path (ICT) is greatest tackled in the summertime when the excessive peaks are freed from snow. Not like extra in style routes, such because the Colorado Path or Lengthy Path, a part of this thru-hike is within the desert, which might make timing a bit tougher.

Many thru-hikers try to finish the desert portion by mid-June, which can be when the Sawtooths change into satisfactory. Heading southbound, the Owynee can nonetheless be fairly sizzling by means of August. On the finish of the day, some compromise will seemingly be wanted, and hikers will both must plan for sections, hope for favorable climate, or simply cope with the situations through the use of applicable gear.

Problem of Path

Although it’s named the Idaho Centennial “Path”, in actuality, the ICT is extra of a route or path idea. Most of the trails are overgrown or non-existent. The distant nature of central Idaho results in lengthy distances between resupplies, and the situations are fairly rugged at instances. Potential hikers should be versatile and have the mandatory abilities to deal with this route safely.

For all of those causes, outlined in additional element beneath, it’s considerably tougher than any of the Triple Crown trails or different in style thru-hikes.

ROUTE FINDING

Not like extra in style thru-hikes, the Idaho Centennial Path is just not a totally blazed route. There may be not a FarOut app or a particular map set for this path. As an alternative, hikers might want to buy their very own paper maps for the quadrants that embrace the paths the ICT makes use of, obtain a GPX file to a GPS app reminiscent of GAIA GPS, or a mixture of each. Whereas there are some ICT markers within the Owhyee desert, most path junctions are usually not marked. Hikers want to concentrate to the place they’re going, perceive how you can learn the panorama, and have the ability to make navigation choices each single day.

The opposite route-finding piece that’s completely different from different long-distance hikes is the standard of the paths. There are numerous locations the place the paths the ICT follows haven’t been cleared or maintained for a while. That is very true within the Selway-Bitterroot and Frank Church River of No Return Wilderness areas. The paths are brushy with many downed timber, and the path tread could not even exist in some locations. These situations are gradual to hike in when resupplies are already few and much between. Many thru-hikers select to reroute to roads or better-maintained trails when wanted.

REMOTENESS

One of many unbelievable options of the ICT is how far some sections are from the closest city. This additionally implies that hikers should be rather more self-reliant and actually perceive their limitations to remain secure. Many sections would require a number of hours of hitchhiking on dust roads to succeed in the closest city. Lots of these cities are extremely small and wouldn’t have many facilities to assist out a hiker. 

Whereas your complete route is rather more distant than a normal thru-hike, two sections actually stand out. The Selway-Bitterroot Wilderness and Frank Church River of No Return Wilderness are massive swaths of protected land which can be adjoining to one another. Collectively, they make up an enormous space in central Idaho that’s distant from any city of any measurement. For reference, it’s regular to hike nearly 300 miles with out resupplying in any cities on this part. Hikers usually must have their meals flown into Forest Service guard stations or delivered to non-public landowners with an airstrip on their property. There are bailout factors and reroute choices, however even these roads are usually removed from any cities. 

One other part to plan for is the Owyhee Desert between the Nevada border and I-84. The route right here primarily follows double tracks and dust roads. It’s potential to discover a experience by climbing out to the principle dust highway to the east, however the nature of climbing in a waterless desert makes this part critical. It may take nicely over one to 2 hours to get assist by automobile in some areas, so care is required to remain secure.

WATER ACCESS & SUN EXPOSURE

Apart from probably the most northern part of the path, which is technically a part of the Pacific Northwest, a lot of the path is arid and dry. There are lengthy waterless sections on the 100-mile State Line Path along with the Owyhee Desert. Most water carries max out at about 20 miles on the State Line part, although it may be sizzling in the summertime. Within the Owyhee desert, most hikers cache water as in any other case there’s a 30+ mile and a 55-mile lengthy stretch with out quick access to water. A 4×4 automobile or dust bike is required to cache water on this part. 

The warmth also can present an enormous problem throughout a thru-hike. Temperatures within the Owyhee and on the Columbia Plateau can attain into the higher 90s even in late August. There may be little shade, simply occasional swaths of sagebrush. Most hikers attempt to deal with this part in early June when it’s barely cooler. Some even will hike this space earlier within the season, then end the remainder of the path in the summertime. Temperatures can be within the 80s within the northern components of the state. The elevation alongside the Salmon River is sort of low, and there are a lot of burn areas that may warmth up shortly. With correct planning and good warmth tolerance, these sections are nonetheless satisfying.

A gallon jug, several smart water bottles, and several water bladders are lined up on the ground surrounded by other pieces of gear. In total, the containers hold about 15 liters of water.

LIMITED OUTSIDE RESOURCES

Although the ICT was first established in 1990, few folks have efficiently accomplished end-to-end thru-hikes. Whereas it’s arduous to seek out actual estimates on the variety of completers, it’s secure to say that even with its current progress in reputation, just a few folks full it annually. Many individuals do deal with sections, notably native Idahoans, however as a result of decrease degree of curiosity on this path, there are fewer planning assets and on-trail assist. There’s a Fb web page devoted to the ICT the place these curious concerning the path can get their questions answered, and a guidebook was launched in 2023. Idaho State Parks and Recreation also can assist to reply questions and has some planning assets on their web site, together with overview maps and a few primary planning info. 

Potential hikers ought to observe there may be not a longtime path tradition or assist community for thru-hikers. Whereas folks in Idaho are usually pleasant and hitchhiking isn’t a problem, any path magic will probably be spontaneous from people who find themselves genuinely involved about your well-being on account of not figuring out a lot concerning the route. Don’t anticipate finding hiker reductions, water caches, or hostels whereas climbing the ICT.

WILDFIRES

Whereas a lot of the West is susceptible to wildfires, they’ll shortly derail an Idaho Centennial Path hike. Central Idaho, particularly, is susceptible to devastating wildfires as a result of decrease elevations and arid local weather alongside the rivers. As soon as a fireplace begins, they’re troublesome to combat as a result of distant nature of the world and rugged terrain.

Nevertheless, fires can begin just about anyplace alongside the path. It’s good to be diligent when climbing and look ahead to smoke. Carrying a satellite tv for pc messaging machine is useful to get updates on the standing of fireplace situations when climbing within the Selway and Frank wilderness areas. Be ready to reroute if mandatory with a purpose to keep away from hearth closures.

NORTHBOUND VS. SOUTHBOUND

As with every long-distance hike, these seeking to thru-hike must plan correctly for the time and funds mandatory to finish a 1,000-mile path. 

Although most skilled thru-hikers and Idahoans advocate climbing the ICT NOBO, relying on the 12 months, SOBO could be a greater possibility. Typically talking, fires and snowpack are the principle causes for selecting a NOBO thru-hike. By climbing the desert first, thru-hikers can decide an earlier begin date. An earlier begin date interprets to ending the path earlier within the hearth season.

The draw back is that the Sawtooths should still be coated in snow by the point most hikers get there. We hiked the ICT southbound and had been lucky to solely encounter two fires and no snow. Nevertheless, this isn’t usually the norm, and our expertise within the Owyhee was a lot hotter because of this.

Getting There

Each the northern and southern termini are pretty distant and might take a while to succeed in. 

SOUTHERN TERMINUS

The southern terminus of the ICT is positioned on the Idaho-Nevada border about two miles east of Murphy Sizzling Springs, ID. Murphy Sizzling Springs is a small unincorporated group positioned on the Bruneau River, and each the group and terminus are roughly three and a half hours from Boise. There are numerous miles of dust highway to drive on the best way, and hitchhiking to this terminus can be troublesome. Most thru-hikers organize a shuttle with household, associates, or by posting on the ICT Fb group.

NORTHERN TERMINUS

The ICT formally ends at American Falls, which is a few half mile south of the Canadian border within the panhandle. There’s a trailhead with a bear field about eight miles from the falls, however the drive to the trailhead is lengthy. In whole, the drive from the trailhead to Spokane is about three hours. Just like the southern terminus, most hikers organize a shuttle by means of household, associates, and path angels. We had success hitchhiking, however it may be powerful to hitchhike round Spokane. 

-Planning Your Itinerary (any useful resource suggestions, i.e., apps, web sites, books, in addition to a particular itinerary define if there are consensus greatest campsites or greatest routes)

Assets are restricted in comparison with different long-distance hikes, however can be found with sufficient looking out! The Idaho Division of Parks and Recreation web site is a superb place to begin for common info and planning. We’ve got additionally discovered the Idaho Centennial Path Updates and Data group on Fb to be fairly useful. There are different web sites with helpful info that may be discovered with sufficient digging, together with a web page that outlines the place to ship packages for the distant wilderness sections. A brand new guidebook was printed in 2023 and is out there on Amazon and at REI. 

As for maps, there isn’t a FarOut app for this path. A GPS app reminiscent of GAIA, OnX, or CalTopo is a good suggestion as a result of terrain. Idaho Parks and Rec has a GPX file that may be downloaded from their web site and uploaded into your navigation app of alternative. Paper maps are additionally a good suggestion on this route, not less than as a backup. The Nationwide Geographic Sawtooth Wilderness Map and the Cairn Cartographics Selway-Bitterroot Wilderness Maps are waterproof and supply good element. The Benchmark Highway & Recreation Atlases present , large-scale overview at an inexpensive value and are additionally helpful for caching meals or water.

Wildlife

A variety of wildlife is discovered throughout Idaho as a result of variety of terrain and elevation. Hikers must be ready to come across Grizzly Bears, Black Bears, Wolves, Mountain Lions, Moose, Deer, Elk, Coyotes, Rattlesnakes, and so forth. Grizzly Bears are much less widespread in Idaho than in neighboring Canada or Glacier Nationwide Park, however it’s nonetheless urged to take precautions by carrying bear spray and storing meals correctly from the Sawtooths north to the terminus.

We had been stunned on the variety of rattlesnakes – they’re quite common alongside the Selway and Salmon rivers as a result of decrease elevations in these areas. In fact, they are often discovered within the Owyhee Desert as nicely. Most different animals generally encountered are skittish or are bored with people when given correct house. 

Mosquitoes are the principle bug concern in Idaho. There are some locations the place they’re fairly aggressive, however many locations the place there are few, if any. Typically, picaridin lotion or a totally enclosed tent will probably be sufficient to remain sane. We didn’t discover any issues with ticks on this hike, although there could also be extra of them in June. Probably the most fascinating bug present in Idaho is the Mormon Cricket, which can expertise inhabitants booms or surges. Throughout these surges, they are often present in nice numbers within the Owyhee Desert, protecting the bottom and turning into a hazard for drivers and cyclists alike.

The place to Resupply

One of the vital distinctive points of an ICT thru-hike is having meals flown into the backcountry touchdown strips within the Frank Church and Selway-Bitterroot Wilderness Areas. As a result of the path by means of these sections is so distant and lengthy, most thru-hikers will need to have their meals flown in. There are a number of Guard Stations run by the Forest Service that can settle for and maintain packages, in addition to some non-public landowners who’re supportive of ICT thru-hikers. 

The US Postal Service contracts with native pilots to ship mail to those distant touchdown strips. Which means that for many places, it’s comparatively inexpensive to ship a resupply field. Simply mail your package deal by means of your native put up workplace and pay the common package deal payment.

That stated, permission from the landowners is required earlier than any packing containers could be despatched. When permission is granted, the airstrip house owners will present the suitable mailing deal with. We additionally recommend contacting Smith Air for extra info, as they ship the packages on this space or can direct you to a greater useful resource.

Resupply choices are restricted on the ICT, so pre-planning not less than half, if not all, resupplies will probably be mandatory. Most of the cities alongside the Idaho Centennial Path have put up places of work that can maintain common supply packages. Most postal employees are even aware of hikers. Particular consideration is required to resupply within the Selway-Bitterroot and Frank Church River of No Return Wilderness areas. Listed here are among the widespread resupply places to think about, although not each hiker will resupply at each location.
