Tuolumne Whitewater Rafting 1-Day Trip
Tuolumne whitewater rafting is a thrill-packed one-day adventure that’s the perfect add-on to any Yosemite National Park vacation.
Spilling from the highlands of Yosemite National Park, the Wild & Scenic Tuolumne River is often considered California’s premier whitewater rafting trip. When done as a day trip, this 18-mile stretch of nearly non-stop Class III-IV whitewater just below Hetch Hetchy is nothing short of epic, especially during high-water spring trips when the river roars with fresh snowmelt. Paddlers can expect technical and challenging rapids, including intricate boulder gardens, narrow chutes, and big drops like notorious Clavey Falls, where rafts plummet eight vertical feet over a dramatic series of staircase drops before having to dodge a boat-munching hole at the bottom. A true wilderness trip, a Tuolumne whitewater rafting day trip pairs perfectly with a trip to the Yosemite region.
Insider tip: Make this trip a 2- or 3-day adventure for the chance to explore all of the hidden wonders that the Tuolumne has to offer like Gold Rush history and hikes up spectacular side streams that lead to waterfalls, secret swimming holes, and natural waterslides.

Whitewater & Water Levels
The water on the Tuolumne River is released from hydroelectric facilities located upstream. These water releases are solely controlled by the city of San Francisco and its Hetch Hetchy Reservoir; whitewater rafting companies have no influence in the schedule. It is important for our guests to understand that the water flow on the Tuolumne is directly related to the amount of snow in the Sierra Nevada, as well as the demand for water and hydropower. On Tuolumne River rafting trips, we often have to wait for the dam-released water to reach our campsite, causing a later start in the day.
When spring run-off is highest, water is released from the reservoirs in abundance to make room for the in-flow. This can lead to high flows on our trips. Peak run-off usually occurs between mid-May and mid-June, but can vary widely from early May into July. High-water trips equate to a more intense whitewater experience; a high level of physical fitness is recommended. Water temperatures are coldest during the high water period and wetsuits will be required. In reality, the water is quite cold even in late summer, but lower flows and warm air temperatures mitigate the risk of hypothermia.
Before booking your trip with OARS, there are a few important considerations we’d like you to know about.
Reservations and Payments
Full payment is required at the time of booking.
Payments can be made by check, money order, eCheck, wire transfer, Visa, MasterCard, American Express, or Discover. Prices are in US Dollars, and all payments must be made in US Dollars. Payment of the deposit establishes your acceptance of our complete Terms and Conditions. Individual departures and trip capacity are strictly limited by the managing agency. Your payment is fully refundable for 48 hours, less a 3% processing fee, after making a reservation when you reserve a trip 7 days or more prior to departure.
Cancellations and Refunds
Canceling your trip after your deposit is processed will incur cancellation fees because OARS has absorbed costs on your behalf and will turn others away who would like to book the spaces we’re holding for you. If you must cancel your reservation after the rescission period described above, your cancellation fee will be determined according to the schedule below.
We regret that we cannot make exceptions to the cancellation policy for any reason, including foul weather, poor air quality, wildfire activity, acts of terrorism, civil unrest, or personal emergencies. For these reasons, we strongly urge you to consider purchasing a travel protection plan.
| Date of Cancellation | Cancellation Fee |
|---|---|
| 30 or more days before your trip | $30/person |
| 29 – 7 days before your trip | $50/person. The remainder of your trip payment can be transferred to another trip within the same year (or to a credit account for the following year). No refund. |
| 6 days or less before your trip | 50% of the trip cost can be credited to another trip (within the same year). No refund. |
| Late arrivals or “no-shows” | No refund or credit |
Please note that different deposit/cancellation policies may apply for charter groups. Refer to the group organizer’s confirmation email for details.
Canceled Trips
OARS reserves the right to cancel any trip due to insufficient registration or other factors that make the trip impractical to operate. In such instances, we will inform you at least 7 days prior to departure. Do not make non-refundable travel arrangements until you have verified with OARS that your trip is confirmed.
If a trip must be canceled or postponed due to force majeure (factors outside the control of OARS), OARS will provide full credit for payments made toward future travel or a refund less a $30/person service fee and any non-refundable payments made on your behalf to 3rd-party suppliers. OARS will make good faith efforts to recover deposits made on your behalf to 3rd-party suppliers; however, we cannot guarantee recovery of any or all of the advance payments made. OARS is not responsible for expenses incurred by participants in preparation for a canceled trip.
Transfers
If you need to move your reservation to a different trip during the same year, or to a credit account for the following year, there is a $15/person fee up until 30 days prior to departure for a one-time transfer of your payment. If we are 29-7 days prior to your trip departure, there is a $50/person fee to transfer to another trip, within the same year or to a credit account for the following year. If we are 6 days or less prior to departure, 50% of your trip cost can be credited to another trip within the same year only.
