Backcountry Camping in Idaho: Permits, Routes, Bear Notes

The first thing to understand about Idaho backcountry is that the maps lie a little. Not deliberately — but the green polygon labeled "Frank Church–River of No Return Wilderness" reads as a single unit on a screen, and on the ground it is a 2.4-million-acre mosaic of granite, ash flows from the Challis volcanics, and river canyons cut so deep that the Salmon was running its present course while the the Sawtooth batholith was still being unroofed. You can hike four days from a trailhead and meet exactly one outfitter string and a Forest Service trail crew, and that is in a good year.

Most writing about backcountry camping here treats the state as a warm-up for Glacier or a discount Yellowstone. That is lazy. Idaho's wilderness areas are bigger, emptier, and structured around rivers rather than peaks, which changes everything about how you plan — water is abundant, but the trails climb out of and back into drainages constantly, and your daily mileage will be lower than your topo suggests. I plan in elevation gain, not miles. You should too.

Where "backcountry" actually means something in Idaho

The state has six designated wilderness areas of consequence for backpackers, plus a long list of roadless areas managed by the Forest Service that function as de facto wilderness. The big ones, in rough order of how often I send people there:

• Sawtooth Wilderness (Sawtooth National Recreation Area, north of Stanley) — the postcard country. Alice, Toxaway, Sawtooth Lake. Granite, lake basins, heavy use on the loop trails.
• Frank Church–River of No Return Wilderness (Salmon-Challis and Payette National Forests) — the largest contiguous wilderness in the lower 48. River-corridor camping along the Middle Fork and Main Salmon, plus genuinely remote interior trails out of Yellow Pine and Big Creek.
• Selway-Bitterroot Wilderness (Nez Perce-Clearwater National Forests, east of Lowell) — Selway River corridor, brutal climbs out, and the homeland of the Nez Perce (Nimíipuu), which is worth sitting with before you walk in.
• Hells Canyon Wilderness (Wallowa-Whitman/Payette) — deepest river gorge in North America, hotter than people expect, snake country in summer.
• Cecil D. Andrus–White Clouds Wilderness (designated 2015, north of Ketchum) — alpine, quieter than the Sawtooths next door, and my personal first pick.
• Gospel Hump Wilderness (Nez Perce-Clearwater) — almost nobody goes. Worth the gravel road to get there.

Outside the wilderness, the High Divide country between the Pioneers and the Lost River Range, the Selkirks up near Priest Lake, and the Owyhee canyonlands in the southwest will all reward a backpacker willing to read a map carefully. Owyhee in particular — high desert, BLM, almost no signed trails — is the closest thing Idaho has to choose-your-own-adventure terrain.

The permit picture, which is less complicated than people make it

For walk-in backcountry camping in the Sawtooth, Frank Church, Selway-Bitterroot, and the other Forest Service wilderness areas, there is no per-person backcountry permit required for foot travel. You fill out a free self-registration card at the trailhead box. That is it. People show up expecting a Glacier-style quota system and are surprised; the Forest Service generally manages these landscapes by access difficulty rather than paperwork.

The permits that do matter, and that catch people out:

River permits

If your "backcountry trip" involves floating the Middle Fork of the Salmon, the Main Salmon, the Selway, or the Snake through Hells Canyon, you are in lottery territory. The Four Rivers Lottery runs through Recreation.gov and the application window opens in winter for the following summer's launches. The Selway is the hardest permit in the country to draw. If you are hiking in to a riverside camp and not launching a boat, you do not need this permit — but you will share the corridor with people who did.

State park backcountry

Idaho's state parks largely don't do backcountry the way the wildernesses do; they are car-camping and yurt operations. Priest Lake and Farragut have walk-in sites that are pleasant but not backcountry in any honest sense. Idaho Parks and Recreation handles reservations through their own system, separate from federal sites.

Trailhead parking and access fees

The Sawtooth NRA charges a trailhead parking fee at the major trailheads (Pettit Lake, Iron Creek, Tin Cup, Redfish). It is a per-vehicle, multi-day pass; check current rates with the Forest Service before you go. The fee is small and it is the only money the agency will ask of you for a week-long trip into the Sawtooths, which seems like a bargain to me.

Routes I send people on, by experience level

I have walked most of these, some of them several times across different decades, and I will tell you which one I would not repeat.

First backcountry trip in Idaho: Alice–Toxaway Loop, Sawtooth Wilderness

From the Tin Cup Hiker trailhead at Pettit Lake (south of Stanley off ID-75), this is roughly 19 miles, two passes, and an honest introduction to Sawtooth granite. Go in late September if you can — the crowds thin, the bugs are gone, and the larches in the side drainages do their brief gold thing. Camp at Twin Lakes the first night, not Toxaway, which gets hammered. (This is one of the loops where I will gently push back on anyone who calls it a hidden gem: it is on every Idaho list, the trail is well-graded, and you will see people.)

Intermediate: Big Boulder Lakes, White Clouds Wilderness

From the Livingston Mill trailhead (gravel access road off ID-75), maybe 14 miles round trip with a stiff climb to the lake basin. The White Clouds were a proposed open-pit molybdenum mine site in the 1960s; the fight to stop it shaped Idaho conservation politics for fifty years and ended with the 2015 wilderness designation. Walking in there carries that history. Fewer people than the Sawtooths next door, comparable scenery, harder access.

Committed: Bighorn Crags, Frank Church

From the Crags Campground trailhead (long drive on FR 113 out of Salmon — plan for a full day on dirt). The route into Ship Island Lake is 20-some miles one way through some of the most striking high country in the Rockies. This is grizzly-adjacent terrain, genuinely remote, and self-rescue is the only rescue for the first day or two. I would not bring a first-time backpacker here; I would bring a strong second-timer who has done a shoulder-season trip and knows their stove works in wind.

The one I would not repeat: lower Selway in August

Beautiful river, brutal climbs out of the corridor, rattlesnakes, and in a dry year the smoke settles in the canyon and does not leave. Go in June or skip it.

Bears: what is actually true

Idaho has both black bears and grizzlies, and where you are matters more than what season it is. Grizzlies are established in the Selkirks and Cabinet-Yaak in the north, and they range through the eastern edge of the state — the Centennials, the Henrys Lake area, and increasingly through the Frank Church and into the Sawtooths' eastern approaches. The official recovery zone maps lag the actual animals by a decade. Plan as if you are in grizzly country anywhere east of US-95 and north of the Snake River Plain, and you will not be wrong often.

Practically:

Hang or canister, and the Forest Service has been moving toward requiring approved bear-resistant food storage in more areas — the Sawtooth NRA has specific food storage orders in effect in some drainages and they change. Read the trailhead board. An IGBC-approved canister is the simple answer; I carry one north of the Snake regardless. Cook 100 yards from your tent, downwind, and do not be the person who brings a freeze-dried curry into a basin with one campsite and expects the next party not to notice. (I once shared a lake basin in the Crags with a group who had — well, they learned.

Bear spray works. Carry it accessible, not buried in a pack lid. In grizzly country I carry it on a chest holster while hiking and keep it in the vestibule at night. Black bears in the Sawtooths are mostly a food-conditioning problem, not a predation problem, and the answer is the same: clean camp, secured food, no cowboy coffee grounds dumped behind a rock.

Gear notes that actually matter here

Idaho nights are colder than the latitude suggests because the air is dry and the elevations are real — basin camps in the Sawtooths sit at 8,500 to 9,500 feet, and I have had frost in the second week of August at Sawtooth Lake. A 20-degree sleeping bag is the floor for shoulder season; bring a liner if you sleep cold. Your three-season tent wants a real footprint because the granite slabs will chew up a bare floor in two trips.

On stoves: canister stoves work fine through September in most of the state, but above 9,000 feet in a cold snap a remote-canister or liquid-fuel setup is more honest. Water is generally abundant — the geolgoical structure of Idaho's wilderness is river-canyon-river-canyon, and you cross creeks constantly — but filter everything; cattle grazing happens in adjacent allotments and giardia is real. For broader kit thoughts I keep an updated gear page, and for trip-planning shortcuts the trails index and our hiking section have route notes that go deeper than I will here.

Timing, and why I almost always say September

Snow lingers in the Sawtooth and White Cloud high basins through early July most years; the Bighorn Crags road is often not passable until late June. July and August are the warm window, but they are also wildfire season, and a trip planned for the Frank Church in August has maybe a one-in-three chance of being smoked out or closed outright. September is the answer: cold nights, clear days, no bugs, low crowds, and the rivers low enough to make stream crossings trivial. The tradeoff is shorter days and the real possibility of an early snow above 9,000 feet. I will take that trade every year.

For longer planning horizons keep an eye on AllTrails Idaho for trip reports (filter for recent dates and read the negative ones — they are more honest), and the relevant ranger district pages on the Forest Service site. Our own parks overview has the basic orientation if you are new to the state.

Honest take

If you have a week and you are willing to drive on dirt for half a day, the White Clouds or the Bighorn Crags will give you the kind of trip that Glacier and the Tetons stopped offering twenty years ago. The permit picture is light, the agencies trust you to behave, and the country is big enough that you can still be alone on a Saturday in September. Bring more layers than you think, plan in elevation gain instead of miles, and do not bring the curry.
