Yes, everyone knows about the American River (gold was discovered here at Sutter’s Mill in 1848, launching the Gold Rush). And yes, in summer it seems as if almost everyone with an inner tube comes here.

It’s true the South Fork (less turbulent than the North and Middle Forks) of the American is the most popular stretch of whitewater in the state. And why shouldn’t it be? It has history and scenic beauty, and once you’re plunging through a rapid, the roar of water in your heart and your ears, you might as well be alone anyhow.

Winter melt makes spring flow the fastest, and by summer things have slowed, but a summer raft trip down the South Fork still offers plenty of zip. And where it doesn’t, there is nothing like spinning lazily beneath blue sky ringed by green and gold foothills. And there are rapids too—a parade of them through the steep granite canyon known as the Gorge, not to mention the standing waves and growling holes of the Triple Threat rapids.

If you’re experienced you can go it alone; if not (or you want someone else to do the work), sign on for a trip with Grass Valley–based Tributary Whitewater Tours . They’ve been running the river for over 25 years and they offer a range of trips: half-day, full-day, and a two-day trip that covers 21 miles of the South Fork and includes camping. You haven’t lived until you’ve fallen asleep to the soft grumbling rush of a river.
