Essential permits, gear & wilderness planning.
Main Salmon permit lottery
A permit is required to float the Wild section of the Main Salmon (Corn Creek to Long Tom Bar) during the controlled season, June 20 to September 7. Permits are allocated by competitive lottery on Recreation.gov, with applications December 1 to January 31. A maximum of eight float parties launch per day. Outfitters carry permits for commercial trips.
Bighorn Crags permit
Wilderness permits for backpacking the Bighorn Crags are self-issued at the trailhead kiosk, with no quota and no fee. Fill it out accurately for safety and use data. Always check the Salmon-Challis National Forest website for current regulations before your trip.
Bush plane charters
Bush planes are the practical way into this roadless wilderness. Book early for peak season with operators out of Salmon such as Salmon Air. Prices depend on passenger count and gear weight, so expect several hundred dollars per person round trip, and weigh your dry bags before you fly.
Leave No Trace & food storage
Pack out everything you pack in. On the river use the outfitter groover and WAG-bag system; in the backcountry dig catholes and carry a bear canister or Ursack. Camp only in durable, established sites and minimize impact throughout The Frank.
Go late June through August
July is the sweet spot: good river flows, warm weather, and melted-out high country. June brings bigger, colder whitewater and lingering snow in the Crags; August has lower flows and can carry wildfire smoke. Always check current flows and forecasts before you go.
This is an advanced trip
You combine multi-day Class III–IV rafting with strenuous backpacking above 8,000 ft. Come in excellent shape with prior experience in both, or go with a commercial outfitter who provides guides, food, gear, and handles the permits and bush-plane logistics.
Pack for a huge temperature swing
This trip spans two climates in one week. The river canyons can push past 90F and bake you on the water, while camps above 8,000 ft in the Bighorn Crags drop near freezing at night and draw fast-building afternoon lightning. Bring sun protection and light layers for the float plus a warm insulating layer, hat, gloves, and a full rain shell for the high country. Plan any ridge or summit scrambles for early morning, before storms build.
Split your gear into two kits
Because you raft first and backpack second, sort everything into a river kit and a mountain kit before you fly in, ideally back in Salmon on day one. That way your wet river gear can be cached cleanly with the outfitter at the takeout while you carry only backpacking essentials into the Crags. It keeps your pack lighter and your bush-plane baggage weight easier to manage in both directions.
Frank Church River of No Return: questions before you go
Salmon idaho: the questions people ask most.
Floating the Wild section of the Main Salmon (Corn Creek to Long Tom Bar) requires a permit during the controlled season, June 20 to September 7, allocated by competitive lottery on Recreation.gov with applications December 1 to January 31. Backpacking the Bighorn Crags requires only a self-issued wilderness permit at the trailhead, which has no quota and no fee. Commercial outfitters handle the river permit for guided trips.
Most expeditions stage in Salmon, Idaho (4–5 hours from Boise, 2.5–3 hours from Missoula) and fly in by bush plane, since this is the largest roadless wilderness in the Lower 48. The Main Salmon launches at Corn Creek, about 45 miles west of North Fork. The Bighorn Crags are reached from the Crags Campground trailhead. Bush-plane charters out of Salmon, such as Salmon Air, are the practical way in and out.
It is an advanced trip. You combine multi-day Class III–IV whitewater on the Main Salmon with strenuous backpacking in the Bighorn Crags, gaining 2,000–3,000 ft to camps above 8,000 ft. You should be in excellent physical condition, comfortable in remote wilderness, and experienced in both rafting and backpacking, or go with a commercial outfitter.
Late June through August. July is ideal, with good river flows, warm weather, and melted-out high country. June brings bigger, colder whitewater and lingering snow in the Crags. August has lower flows and can carry wildfire smoke. Always check current river flows and weather forecasts before your trip.
It varies. Commercial outfitter trips typically run $4,000 to $7,000+ per person, covering guides, food, gear, and bush-plane charters. Private trips reduce guide fees but require winning the river lottery, buying gear, and paying directly for bush-plane flights (often $500–$1,000+ per person) and shuttles. Check current Recreation.gov and charter rates when you plan.
Either airport works, but Missoula (MSO) in Montana is usually the shorter and simpler approach at roughly 2.5 to 3 hours of driving to Salmon, versus 4 to 5 hours from Boise (BOI). If your schedule allows, flying into Missoula saves time on both ends and leaves more buffer for the mountain drive and any bush-plane weather delays. Boise can still make sense if flights or fares line up better, or if you plan to add days in the Sawtooths. Allow generous drive time either way, since the route is long and mountainous.
The Frank Church Wilderness is rich in wildlife. On the river you might spot bighorn sheep, deer, elk, river otters, and bald eagles. In the Bighorn Crags, look for mountain goats, pika, and marmots, with black bears and wolves present but rarely seen. Keep a safe distance and never feed wildlife.
Yes, the Four Rivers Lottery is required. One lottery covering four wild rivers. Applications name the river, the launch date and the party.
Application window: applications are accepted 1 December to 31 January, results go out on 14 February, and a winning reservation must be confirmed by 15 March or it is revoked. The controlled season runs 28 May to 3 September..
One of the hardest float permits in the country. The Middle Fork in July is the single worst draw of the four rivers.
Apply for all four rivers, not just the famous one, and take shoulder dates. Cancelled permits are re-released through the season, so the post-lottery pool is worth watching rather than writing the year off.
