North America’s deepest river gorge is deeper than the Grand Canyon, and you can only get in by boat

Hells Canyon runs deeper than the Grand Canyon

You stand at the rim of Hells Canyon and the river sits nearly 8,000 feet below you. That drop makes this the deepest river gorge in North America.

The Snake River runs more than 100 miles through here with no road crossings between Hells Canyon Dam and Lewiston, Idaho. The sandy beaches, the ancient rock art, the old ranch sites all sit along the water.

The only way to reach them starts with a boat.

A river that carved a border over millions of years

The Snake River cut this canyon along the line between Oregon and Idaho across millions of years. About 67.5 miles of it carry a Wild and Scenic designation, split into roughly 31.5 Wild miles and 36 Scenic miles.

The Wild section runs from Hells Canyon Dam downstream to Upper Pittsburg Landing, where the river drops to its deepest and most cut off from the world.

The Nez Perce, or Nimiipuu, have lived here for thousands of years, and their petroglyphs and pictographs still line the walls.

Float two to six days through Class IV water

You launch from below Hells Canyon Dam and take out wherever the trip ends.

Common routes run to Pittsburg Landing at 32 miles, Dug Bar at 51 miles, or Heller Bar near Asotin at 79 miles, so a trip lasts anywhere from two to six days.

The whitewater shifts between Class II and Class IV in normal summer flows, and the difficulty changes with the water volume. Licensed outfitters bring all the gear, meals, tents, and guides.

Kids as young as seven can come along.

Wild Sheep and Granite hit the hardest

Wild Sheep Rapids is the longest rapid on the river and one of the best-known Class IV runs in the Pacific Northwest.

It throws big waves and powerful hydraulics that shift with the water Hells Canyon Dam releases upstream.

A couple of miles down sits Granite Rapids, named for Granite Creek that pours in from Idaho’s Seven Devils Mountains. At the right water level, Granite kicks up a massive curling wave that experienced rafters chase.

Waterspout, Rush Creek, and Sluice Creek round out the run from Class II to Class III.

Sleep on sand beneath the darkest sky

Each night you pull onto a sandy beach or a flat bench under the pines and set up camp. You get no cell service, no road noise, and almost no light pollution this deep in the canyon.

The outfitters handle the full camp with tents, sleeping pads, camp chairs, and a river kitchen. Dinners run gourmet, with fresh-baked breads at night and hot coffee waiting at sunrise.

Summer days usually sit between 80 and 95 degrees, and the river warms up enough for a swim.

See the deepest stretch in a single day

If you only have a day, a jet boat gets you into the canyon fast.

Tours launch from several points, including Hells Canyon Creek Boat Launch about a mile below the dam and from northern spots near the Lewiston-Clarkston and Asotin area.

Your captain talks you through the geology, the Native American history, and the ranching past as you go. The boats run through whitewater, stop at old ranch sites, and pull close to walls where rock art shows.

Most include a riverside lunch and last a half day to a full day.

The mail boat that has run since 1919

One of the most remote mail routes in the lower 48 still runs through Hells Canyon by jet boat. Boat delivery on the Snake River started in 1919, back when miners and ranchers had no road to reach.

The mail boat still goes out weekly, dropping letters, packages, groceries, and supplies at about a dozen ranches and year-round homes.

You can ride along, watching the carrier stop at riverside mailboxes and trade words with ranchers who sometimes show up on horseback. The round trip covers nearly 200 miles and takes about 10 hours.

Hook a fish older than your grandparents

The Snake River in Hells Canyon holds white sturgeon, the largest freshwater fish in North America. You fish them catch-and-release only, and some of these giants live more than a century.

They stay penned into a 137-mile reach between Hells Canyon Dam and Lower Granite Dam, which makes this one of the few places you can meet one.

Anglers also go after steelhead, best from November through February, plus smallmouth bass, rainbow trout, and channel catfish. Guided charters run year-round from launch points up and down the river.

Rock carvings that go back 4,500 years

Indigenous peoples left petroglyphs, the carvings, and pictographs, the paintings, all through this canyon. Many sit right along the river and show only from the water or a hike up from a riverside camp.

The Pittsburg Rockart Interpretive Site holds a stretch of carvings, paintings, and scratchings along a short trail the U.S. Forest Service keeps up.

Near the northern end, Buffalo Eddy packs in clusters of carvings dated between 4,500 and 300 years old. The whole Hells Canyon Archeological District sits on the National Register of Historic Places.

A homestead museum you reach by boat

Kirkwood Historic Ranch sits along the Snake River on the Idaho side. You get there by jet boat, raft, or a roughly five-mile hike from Pittsburg Landing.

The ranch dates to the 1880s and later became home to Len Jordan, who went on to serve as Idaho’s governor and a U.S. senator.

Inside the Sterling Cabin, a small museum shows artifacts from pioneer days and from earlier Nez Perce use of the land.

You can walk among the original house, the bunkhouses, a shearing shed, and a blacksmith shop, with signs that lay out daily life in one of the most isolated homesteads in the West.

Watch for bighorns on the canyon walls

The Hells Canyon area supports about 350 wildlife species, and the river gives you the best seat. Bighorn sheep pick their way across the steep walls, most often in the Wild section below the dam.

Bald eagles gather along the Snake in winter, pulled in by the steady fish supply. Elk, mule deer, black bears, mountain goats, and cougars all live here too.

From the boat you might also catch river otters, great blue herons, osprey, and golden eagles working the canyon.

The permit rules you need to know

You need a boat permit year-round for every float and powerboat launch on the Wild and Scenic Snake.

The primary season runs from the Friday before Memorial Day through Sept. 10, when permits go out through the Four Rivers Lottery on Recreation. gov.

The Snake shares that lottery with three other Idaho rivers: the Main Salmon, the Middle Fork of the Salmon, and the Selway.

From Sept. 11 through the Thursday before Memorial Day, you can grab self-issue permits at the major launch sites. Party size tops out at 24, and a licensed outfitter is the easiest route for a first trip.

Explore Hells Canyon National Recreation Area in Oregon

You will find the recreation area spread across 652,488 acres along the Oregon-Idaho border, run by the U.S. Forest Service.

Jet boats and rafts launch from several points, including Hells Canyon Creek Boat Launch below the dam and Heller Bar near Asotin, Washington.

From the south, take Highway 86 east from Baker City, Oregon, or Highway 71 west from Cambridge, Idaho, to reach the dam.

From the north, Lewiston, Idaho, and Clarkston, Washington, give you lodging, dining, and outfitter offices. Low elevation keeps the canyon warm, with summer days hitting 80 to 95 degrees at river level.
