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.
