elcome to Momentum River Expeditions! We offer world-class whitewater rafting in Northern California, home to Mount Shasta, Giant Redwoods, black bear, and some of the most beautiful and remote wilderness areas in the lower forty-eight. This page lists only our Northern California river trips, so please visit our home page for an introduction to Momentum and a complete interactive map of our rafting adventures.

Except for the Smith all of our Northern California river rafting adventures are on the Klamath or are tributaries of the Klamath. The trips range from mellow to wild Class V excitement, and from ½ day outings to multi-day vacations.

The Lower Klamath River cuts through rugged Mountains and has fun splashy whitewater, beautiful side hikes and a staggering amount of wildlife. It is a perfect river for families, beginners, and relaxed adventurers. We also offer scenic ½-day rafting near Ashland Oregon.

The California Salmon River is California’s premier spring run and one of the most spectacular rafting trips in the country. It combines beautiful, lush coastal scenery, cascading waterfalls, emerald-green waters, and unequaled class IV-V whitewater. It is truly world-class.

The Scott River is a sister of the California Salmon with very continuous class V whitewater. It is a great 1-day trip for experienced paddlers.
The Smith River is located in the far corner of Northern California among the giant coastal redwoods. It has a short and unpredictable season so it is rarely run. However, it one of the most magical wilderness runs in the country. Please call for information.
