Views of Mt. Shasta from the River!

The Upper Sacramento River is an excellent Northern California whitewater rafting trip in the spring, providing pure fun on 50 plus rapids in its nearly continuous 30 miles of white water. There are majestic views of Mount Shasta and Castle Crags as the river passes through the beautiful canyons of the Shasta-Trinity National Forest. There is also hardly any rafting traffic! Only minutes north of Redding, the “Upper Sac” is the handiest white water in the northern California mountains. It features beautiful side creek waterfalls, abundant bird life and one of the best trout fisheries in California. We highly recommend this run for active first timers and Class III-IV veterans.

In addition to rafting, the Upper Sacramento area has a lot to offer with stunning scenery and abundant fishing, biking and hiking. The quaint historic railroad town of Dunsmuir has the beautiful waterfalls of Hedge Creek and Mossbrae, caves and soda springs. There is boating and caverns at Lake Shasta to the south and the majestic 14,162 foot Mount Shasta looms just to the north. Accommodations and restaurants are plentiful in Dunsmuir and Mt. Shasta.

Tributary operates under permit from the Shasta-Trinity National Forest and is an equal opportunity service provider.

The Upper Sacramento River is free-flowing, so entirely dependent on snowmelt. Check our Predictions Page for updates for this seasons trips.
