Float 104 miles through the Frank Church-River of No Return Wilderness, past hot springs, pictographs and the third deepest rock-walled canyon in North America.
The Middle Fork of the Salmon runs 104 miles through the Frank Church-River of No Return Wilderness in central Idaho. It was one of the original eight rivers Congress designated Wild and Scenic on October 2, 1968, and over 10,000 people float it each year.
Set a cancellation alert for March 16 at 8:00 AM Mountain Time: every unclaimed control-season launch goes back on Recreation.gov then, and later cancellations are released randomly within 24 hours. Before that, private launches in the control season, May 28 through September 3, are allocated by a randomized lottery, not a weighted one, so a first-timer and a twentieth-timer draw the same. Applications are accepted from December 1 at 8:00 AM Mountain Time through 11:59 PM Mountain Time on January 31, results post February 14, and winners have until March 15 to confirm. Outside the control season, launches are ordinary reservations that open annually on October 1 for the following year.
The river starts 20 miles northwest of Stanley, where Bear Valley and Marsh Creeks meet, and runs 104 miles to the Main Salmon. Almost every private trip puts in at Boundary Creek, at the top, after 26 miles of rough single-lane dirt road that snow keeps closed until late May or early June.
The run is non-motorized and technical: a long series of Class III and IV rapids with few flat stretches to rest in. The canyon deepens as you go, alpine forest at the top giving way to high mountain desert and then to sheer rock walls. Hot springs, prehistoric paintings and abandoned settler cabins sit within a short walk of the water at various points, and the fishing is catch-and-release only.
When the water drops too low, or the Boundary Creek road is impassable, trips fly in to Indian Creek instead and start partway down. Camps are assigned rather than chosen: for launches May 24 through September 30 a camp request form arrives by email 14 days out, and the rest of the year camps are first-come, first-served among designated sites.
The Middle Fork was one of the original eight rivers Congress designated Wild and Scenic on October 2, 1968, and it has stayed that way. Over 10,000 people float it each year, every one of them on a permit, in a corridor with no roads and only a handful of airstrips, ranches and Forest Service stations to show that anyone was ever here.
The water runs clear enough to count rocks on the bottom. You run a dozen rapids before lunch, and by evening the boats are tied off and somebody has found the hot spring. Dinner cooks on a fire pan on the beach. The canyon walls climb until they close off most of the sky, and the night that follows is as dark as night gets in the Lower 48.
Best for: Boaters with real multi-day self-support experience who can read and run continuous Class III-IV without scouting every drop.
Recommended experience: Class III+ river days on your own oars, plus at least one multi-day self-support trip. There is no road out, so the group has to be able to handle a wrap, a flip or an injury on its own.
Not recommended for: First-time rafters, and anyone whose whitewater experience is all day trips with a guide on the oars.
Trailhead information
The standard put-in for the full 104-mile run.
From Stanley, 23 miles west on Highway 21 to Forest Road 579 (between mileposts 109 and 110), then 13 miles on FR 579, then north at Bruce Meadows onto Forest Road 568 for 13 more. Expect 26 miles of rough, single-lane dirt road with heavy traffic. The road is closed seasonally by snow until late May or early June.
Stanley is the closest town; the launch itself has no services.
Trailhead information
A fly-in launch inside the wilderness, used when water levels get too low or the road to Boundary Creek is impassable.
No road access. Boaters fly in.
None. This is a wilderness airstrip.
The lottery control season runs May 28 through September 3, and that window is the trip most people want. Early-season launches get high, cold, pushy water; late-season launches get low water and technical rapids in exchange for warm days and quiet camps. Pre- and post-season launches are ordinary reservations that open October 1 for the following year, which is a real back door if you can handle cold weather.
Snowmelt runoff. High, cold, fast water, and the Boundary Creek road may still be closed by snow into late May or early June.
Crowd level · low
The heart of the control season. Warm days, moderating flows, and every launch spoken for.
Crowd level · high
Low, clear water and cool nights. The control season ends September 3 and post-season reservations take over.
Crowd level · low
Effectively closed. The access road is snowed in and the corridor is not a realistic private float.

Early morning from a river camp, before the boats are rigged, is the only time the canyon is both lit and still. Late light works best in the lower canyon where the walls stand back far enough to let it in.
Mid-morning is when the sun finally clears the rim and reaches the water in the narrow sections. Rapids shoot best from shore with a following boat in frame for scale.
Camps are assigned, so the river never bunches up the way a first-come corridor does. Early-season launches trade colder, higher water for fewer boats; September gives you low water, technical lines and quiet camps.

No. Recreation.gov describes it as a randomized lottery drawing for the control season launch dates, so a first-time applicant and a twenty-year applicant have the same draw.
The lottery application or reservation fee is $6.00 and is non-refundable. On top of that, everyone floating pays a $4.00 per person per day Special Recreation Fee, unless they hold a Salmon Rivers Season Pass.
In the control season group size and trip length are tied together: 1 to 10 people get up to 8 days, 11 to 20 people up to 7 days, and 21 to 24 people up to 6 days. Outside the control season the maximum group size is 24 and the maximum trip length is 8 days.
Yes. Unawarded and declined lottery dates are released for reservation on March 16 at 8:00 AM Mountain Time, and later cancellations are released randomly within 24 hours. Pre- and post-season launches are straight reservations that open annually on October 1 for the following year.
Not in the main season. Your group must stay in the assigned camps listed on the permit, and you may have to share them. For launches May 24 through September 30 a camp request form is emailed 14 days before your launch date. From October 1 through May 23 camps are first-come, first-served among the designated sites.
Inside the control season you must cancel at least 21 days before the launch. A Late Cancellation Penalty blocks you from holding a permit and from applying to the lottery on this river for three years.

The River of No Return proper: bigger volume, more beach camping, and a separate permit in the same Four Rivers lottery.
Different character: bigger water, less continuous technical whitewater, and a separate draw you can enter in the same season.
Another Idaho wilderness river run under a tightly limited private permit.
Even fewer launches than the Middle Fork, and a shorter trip, but the same remote self-support character.
Launches outside the May 28 to September 3 control season are ordinary reservations, released annually on October 1 for the following year, with no lottery at all.
You take cold weather, and possibly a snow-closed Boundary Creek road, in exchange for skipping the draw entirely.
