The Tieton River is the most popular whitewater river rafting trip in the state of Washington during the month of September because it is the ONLY whitewater to be found during the month of September.

After all the other Cascade rivers have run dry, the Tieton River re-hydrates for three purposes: salmon, irrigation and white water rafting.

The Class III rapids and waves on the Tieton River are relentless and, as a bonus, the water, having been impounded behind Rimrock Dam all summer long is, by Washington standards, warm.

Even so, we will provide you and your party members with wetsuits, splash jackets, lifejackets, paddles and all necessary river gear for your thrilling ride through the Tieton River corridor.
