The 10 Biggest Whitewater Rapids

A few rapids loom larger than others when river guides tell tales around the campfire. Here’s a list of the biggest rapids from a river guide’s perspective – in alphabetical order.

Not big enough for you? If you’re an accomplished kayaker or extreme rafter, you’ll want to scroll down to the bottom of this page to see a round-up of rapids that are bigger, but not commonly discussed among river guides.

1. Blossom Bar (Rogue River, Oregon)

You don’t get to be known as “the most expensive rapid in the West” for nothing. A successful run on Blossom Bar requires a straightforward Class IV maneuver simply known as “the move,” but the consequence of a mistake is typically a badly wrapped boat.

There are hundreds of raft frames, camp stoves, groovers, and an immeasurable amount of personal gear buried in the Rogue River below this notorious rapid.

2. Clavey Falls (Tuolumne River, California)

Originally a portage, Clavey Falls was the definition of a Class V rapid in the 1960s. As equipment and techniques have improved, the rapids scale has shifted but Clavey Falls is still a classic Class IV+/V, depending on flows and how you rate rapids.

At normal summer flows (≈1000 cfs), you fall over an eight-foot drop before a complex series of moves to avoid wrap rocks and hydraulics. At higher spring flows, there is a tough Class V maneuver between the famous boat-flipping Clavey Hole and the more menacing hole formed by Dinosaur Rock.

3. Gore Rapid (Colorado River, Colorado)

Gore Rapid is in the heart of Colorado’s famous Gore Canyon on the Colorado River. This large, complex rapid is typically scouted and/or portaged on the railroad tracks on the right side of the river.

The entrance is a particularly tricky affair that offers several options, depending on the river flows, your craft, and your taste for an extra challenge. There is little time to recover from a mistake before the next two rapids, Scissors and Pyrite Falls.

4. Green Wall (Illinois River, Oregon)

Scouting this iconic Class V beast on Oregon’s legendary Illinois River requires scrambling a quarter-mile through boulders punctuated with poison oak bushes. It’s a long, complicated rapid that has a few different routes to choose from, depending on your boat and the water level.

River flows on the Illinois River are volatile, making this rapid different every time you run it. At low flows, you must squeeze through a narrow slot before dodging a pour-over hole that has kept rafts surfing for up to 20 minutes. At high river flows there are several places to flip and little time to recover before the not-so-little Little Green Wall.

5. Ladle (Selway River, Idaho)

Ladle is always intimidating due to its large boulders and holes scattered randomly throughout the rapid. There are options, but none of them are easy!

At low water, the chutes all seem to contain a small rock making passage problematic with huge wrap rocks at the bottom. Sometimes there are trees stuck in the favorable chutes, forcing boaters to take even less desirable ones. At high water the huge boulders form huge holes and continuous whitewater with the “Moose Juice” just downstream.

6. Lava Falls (Colorado River, Arizona)

Lava Falls is the most famous and challenging rapid on the Grand Canyon of the Colorado River. It has a huge hole to avoid at the top, followed by the infamous V-wave which flips 18-foot rafts like bath toys. The adventure ends with large Kahuna waves. This rapid is so famous that it has other rapids named after it: Lava South on the now-dammed Bio Bio River in Chile and Lava North on the Alsek River in Alaska.

7. Mushroom (Tuolumne River, California)

The “Cherry Creek” section of the upper Tuolumne River is the most challenging commercially run whitewater in the United States. Commercial companies require a challenging swim training and warm-up where rocks are intentionally hit to tests the paddlers’ abilities to hold their position. If paddlers fail the test, they have to hike out before the big rapids.

Mushroom (a.k.a. “Skull”) is the biggest rapid on “Cherry Creek” with four distinct maneuvers that command respect. Only a handful of guides in the world have the skills to consistently guide Mushroom with success.

8. Sweet’s Falls (Gauley River, West Virginia)

With reliable flows and big rapids, West Virginia’s Upper Gauley River is one of the most famous rivers in the world. It has several world-renowned rapids, but perhaps best-known is Sweet’s Falls named after John Sweet, the only person to run it on an exploratory descent.

After the main drop is Postage Due, a big rock that you can splat your raft or kayak into. During the fall Gauley season, there is almost always a big crowd watching rafters and kayakers paddle through—it’s like your very own whitewater red carpet.

9. Terminator (Futaleufu River, Chile)

This rapid was named in honor of the first raft descent which “terminated” after an epic flip at the top.

River guides who have been there tell stories from other rapids like Inferno, Mundaca, Mas o Menos, Casa de Piedra, and others, but Terminator is the most notorious. The rapid has three distinct sections, with the middle being the crux.

10. Velvet Falls (Middle Fork of the Salmon River, Idaho)

Velvet Falls is one of the signature rapids on Idaho’s Middle Fork of the Salmon River. At high flows (above five feet), the main drop forms a hole that is tough to avoid and can easily flip any raft.

To make matters worse, the river is fairly continuous downstream, making it difficult to wrangle boats and flip them back over.
