Tuolumne River Rafting Near Yosemite National Park

The number and variety of boats on an OARS trip will vary based on water levels, the number of participants, and other factors we take into account when planning your adventure. Please be aware that in doing so we will ask you to share boat time with your fellow travelers. We don’t assign boats, nor can we guarantee exactly which crafts we bring, but trust us to provide you with the best possible mix for you and others on your trip.

After each active day on the river, we pull ashore to camp for the night. Our first task is to unload the boats using a fire-line of crew and guests to expedite the process. Individuals then collect their waterproof bags and locate an area on the beach to camp for the night. 

While you put up your tent, the guides will set up the kitchen and central dining/seating area with camp chairs. They will also locate a secluded area away from camp to set up the portable toilet, where privacy is assured.

As guides prepare dinner, hors d’oeuvres are served. This is an opportunity to relax, enjoy a drink if you wish, and reflect on the day with your fellow traveling companions.

In the morning, the first wake-up call lets you know that coffee, hot water for tea or cocoa, juice, fresh fruit, and cold cereal are ready. You can fill your mug and grab a bite, then begin to pack up your personal belongings and sleep gear as the guides prepare breakfast. After breakfast, the entire camp is broken down and packed up. Once the guides have all of the gear loaded back onto the boats, we’ll head downstream to see what new adventures await us.

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.
