Little-Known Fact: The Bruneau River is name after Pierre Bruneau, voyageur for the Northwest Trading Co., who explored the region around 1818.

In 1818, a party of French Canadian trappers was exploring the austere sage plateaus of southwest Idaho when they encountered a deep cleft in the lava plains. At the bottom of the gorge ran a river they named the Bruneau.

As I stand on the edge of the same gorge, the swift stream that fills the narrow slot is clear turquoise, riffling over cobble beds and around bars of blond sand and emerald reeds.

Each spring the high summits of the Jarbidge Wilderness Area, barely visible southward, grudgingly release a few weeks of Class III to IV whitewater, providing the easiest way through these canyons. As I floated into the initial gorge, a river otter slipped down the bank to disappear beneath my kayak. Motivated by riparian paradise beyond comparison, I vowed to return.

So now I have braved the 50-odd dirt and gravel miles from the hamlet of Bruneau, south through the overgrazed plains, past the Saylor Creek bombing range, and along the rough spur road to the rim of the gorge, where the Bruneau suddenly reveals itself.

On the west bank an old road switchbacks up to disappear onto the bench above the inner gorge. Sage-hopping a mile or so downstream, I come to a break in the cliffs and descend to the cool, streamside environs. Here the pools are smaller, and cobble beds allow easy crossing for the several reasonable miles I travel before camping.

Many people would like to see the canyons of the Bruneau become a national park or wilderness area. They certainly contain scenery and habitat equal to any. But don’t take my word for it. Go see for yourself.

The Bruneau runs from the Jarbridge Mountains of Nevada north into the Snake River near Boise, Idaho. The town of Bruneau, a few miles below the mouth of the canyon, offers basic needs — lodging and food.

Getting There:

From Boise, drive 45 miles east on I-84 to Hwy. 51, then 20 miles south to Bruneau. Follow the gravel Bruneauen dash Three Creeks Road south for 40 miles to where a sign gives directions to the river. This last 12-mile spur requires patience and dry weather. The final half-mile from rim to river demands a four-wheel-drive vehicle.

Seasonal Information:

For river running, March 15 to May 15 is your best bet; for hiking and tubing, June to early October.

Access is sometimes possible in winter. Summer is hot and dry with highs from 80 to 100 degrees F and nighttime lows from 80 to 50 degrees F. Inner canyon temperatures in July, August, and early September routinely exceed 100 degrees F. Weather conditions are unpredictable in spring and fall.

For river conditions, call (208) 327-7865.


Most notable are California bighorn sheep, mule deer, mountain lions, river otter. Mergansers skim downstream, and pairs of Canada geese shepherd pods of fluffy goslings.

Plant Life:

Permits are not required, but registration is mandatory.


  • Maximum party size is 15.
  • Boaters must carry a life preserver for every person in the party.
  • The use of gas stoves or fire pans is required. There are fire pans at campsites, but stoves are recommended. Kayakers may use a wire-framed fire blanket provided it is covered with a metallic-type material.
  • The use of portable toilets is required.
  • Pets must be under control at all times.


  • Rattlesnakes are common.
  • The lower 25 miles of the 40-mile canyon are badly infested with poison ivy.
  • Sturdy boots, hiking staffs, and dry camp shoes are handy due to repeat stream crossings. Wetsuits are necessary for through-trips.
  • With no trail system, it’s a tough trip for hikers. The area is essentially unhikable March through June in an average year, because spring river runoff fills much of this very vertical canyon from wall to wall with cold, fast water. When the water recedes in July, it reveals a tangle of ankle-busting rocks.
  • Logjams, resulting from an abundance of western juniper trees, demand the continual attention of boaters.
  • Remember that the area is isolated. There are very few roads and access points, so you must be self-sufficient for everything from food to medical aid.

Leave No Trace:

  • To prevent overuse of the river, limit your trips to one per year.
  • If water levels permit, camp on gravel or sand bars to avoid trampling vegetation. Always avoid riparian areas which are the fragile green areas along the river banks.
  • Due to limited carrying capacities, kayakers without raft support may dispose of ash in the river current after they have removed the charcoal from their fire pan or blanket.
  • Carry a tarp large enough to cover the entire area of your kitchen or lunch spot.
  • Respect private property.
  • All LNT guidelines apply.
