The Tuolumne River is considered by many to be the best whitewater trip in California. Its pristine headwaters originate in Yosemite National Park, then surge through eighteen miles of non-stop, Class IV(+) rapids. This incredible whitewater adventure includes intricate boulder gardens, rushing cascades and churning holes, which all combine for action-packed paddling from put-in to take-out.
The Wild & Scenic Tuolumne River flows through a beautiful wilderness canyon. The steep hills are lush green in the spring and golden-yellow in the summer, with oak and pine forests flanked by rocky terraces and sandy beaches. Early season wildflowers blanket the canyon in color. Tumbling creeks and glassy pools adorn the river corridor and its side canyons, creating the perfect outdoor experience for rafting, hiking, fishing and swimming.
- Paddle Raft with Oar Assist—During periods of high water and mid-season one-day trips, we will only offer paddle rafts with an oar assist. The most agile of any boat in the OARS fleet, your guide steers the raft with two hefty oars on a rear-mounted frame while the crew wields paddles up front to provide the necessary horsepower. Helmets required. (Four to six paddlers)
- Paddle Raft—The sportiest of crafts we put on the water, everybody handles a paddle while the guide steers and gives directions from the back of the boat. Paddling together is essential to finding the right run, and teamwork begets success. A thrilling way to brave the rapids! Helmets required. (Four to six paddlers)
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 their Hetch Hetchy Reservoir; whitewater rafting companies have no influence in the schedule. It is important to understand that the water flow on the Tuolumne is directly related to the amount of snow in the Sierra Nevada, as well as demand for water and hydropower.
To increase your safety, we expect everyone to watch our 23-minute Whitewater Orientation video before joining us. Watch at https://www.oars.com/experience/safety/ or call 800-346-6277 to request a free DVD. Please don’t leave home without watching.
We pride ourselves in running a relaxed and flexible schedule. Every trip is different depending upon the group, other trips on the water and sometimes the weather. The following is a sample of what your trip might be like:
We will meet at the La Casa Loma River Store/Tangled Hearts Bakery, at the intersection of Highway 120 and Ferretti Road, eight miles east of Groveland and 30 minutes west of the Hwy 120, Big Oak Flat entrance to Yosemite National Park. We will take a steep shuttle ride down to the river via Lumsden Road to our put-in, where you will meet the rest of your OARS crew. The guides will present an orientation and safety talk and fit you with your safety gear. Then, we’re off!
The Tuolumne is nearly consistent whitewater, with four exciting rapids in the first two miles: Rock Garden, Nemesis, Sunderlands Chute and Ram’s Head. Downstream, we encounter the ultimate thrill: Clavey Falls; this Class IV+ rapid features a series of staircase drops, which deliver unabashed excitement.
Come lunchtime, we’ll pull over to a sandy beach for a delicious picnic. Your guides might lay out an abundant spread of cold cuts, cheeses, veggies and breads, or perhaps a tasty taco salad for roll-your-own burritos. Lunch is always accompanied by fruit, cookies, cold water and lemonade.
The adventure continues with exciting Class III-IV rapids such as Grey’s Grindstone, Thread the Needle, and Hell’s Kitchen. Between rapids, you’re welcome to enjoy a refreshing swim in the calm stretches of cool water.
As we reach Ward’s Ferry and flat water, our river trip draws to a close. At the take-out, an OARS shuttle will be waiting to give you a ride back to your car. You will usually return around 6:00 PM.

Meeting Place & Time
Our meeting place is the La Casa Loma River Store/Tangled Hearts Bakery, approximately 8 miles east of Groveland, at the eastern intersection of Ferretti Road and Highway 120 (30 minutes west of the Hwy 120 (west) entrance to Yosemite National Park). The meeting time is at 8:30 AM. Click here for a Google map.
Getting to La Casa Loma River Store/Tangled Hearts Bakery
La Casa Loma River Store/Tangled Hearts Bakery is on the left-hand (north) side of Hwy 120 at the eastern end of Ferretti Rd, approximately 8 miles east of Groveland and 30 minutes west of the Hwy 120 Big Oak Flat entrance to Yosemite National Park. There is also a Ferretti Road in the town of Groveland just past the Groveland Wayside Park, marked with a flashing yellow light and sign. Do not turn here—this is the western end of Ferretti Road. (If you happen to enter Yosemite National Park, you have driven too far.)
If you are coming from Yosemite National Park, the La Casa Loma River Store/Tangled Hearts Bakery will be on the right-hand (south) side of Hwy 120. The meeting place is about 30 minutes west of the Hwy 120, Big Oak Flat entrance to Yosemite National Park.
These following list of times are estimates. Please allow yourself extra time for the curving mountain roads.

Essential Eligibility Criteria for River Trips
The following are the physical and mental eligibility criteria for all participants on any OARS river trip.
- Ability to remain seated and balanced while in a whitewater craft while holding on with at least one hand.
- Wear a Type V Coast Guard-approved personal floatation device (maximum chest size of 56 inches). Wearing leg straps may be required to ensure proper fit. Where required, properly wear a helmet.
- Ability to independently board and disembark a boat four to ten times each day. This may require stepping into the boat, and then maneuvering your body over and across tubes and fixed objects into a seated position.
- Ability to independently navigate shoreline terrain, including safely maneuvering around and across boulders, rocks, and slippery and uneven surfaces, under low branches, and around vegetation. This includes the ability to maintain your balance near precipitous ledges or cliffs.
- Ability to independently swim in whitewater or swift currents while wearing a PFD. This includes being an active participant in your own rescue, including having the ability to (a) keep your airway passages sealed while underwater, and regain control of your breathing when being submitted to repeated submersion under waves or currents; (b) orient yourself to new “in-river” surroundings; (c) reposition yourself in the water to different swimming positions; (d) swim aggressively to a boat or to shore in whitewater; (e) receive a rescue rope, paddle, or human assistance, and possibly let go of the same; (f) get out from under an overturned boat.
- Ability to swim 100 yards in flat water while wearing a PFD.
- Ability to assist another passenger who has fallen out of the boat by pulling them back in.
- Ability to follow both verbal and non-verbal instructions given by guides in all situations, including during stressful or dangerous situations, and to effectively communicate with guides and other guests.
- Ability to carry personal dry bags and other personal gear (as heavy as 20-30 pounds) uphill from the boats to your camping location and back the next morning, independently, or with the assistance of a friend or family member. (This only applies on multi-day trips)
- Ability to manage all personal care independently, or with the assistance of a friend or family member.
- If taking prescription medications, have the ability to maintain proper dosage by medicating independently, or with the assistance of a friend or family member.
- Ability to remain adequately fed, hydrated, and properly dressed so as to avoid environmental injuries such as hypothermia, heat related illness, sunburn and frostbite.
The above criteria, if not met, will disqualify a person from participating in a river trip with OARS. The criteria exist for your own safety and that of all trip participants. None of the criteria are meant to discriminate on the basis of any physical or mental disability, and are applied uniformly to all potential trip participants, irrespective of the presence or absence of any disability. OARS is committed to making reasonable modifications to any trip for any persons with a disability, so long as they do not fundamentally alter the nature of the trip.
Further Information About Our Expectations of Trip Participants
The following paragraphs are meant to further inform all potential participants of the expectations for all participants in order to promote a safe, enjoyable experience for everyone on a trip. There may be requirements, whether physical or mental, that are not specifically applied “essential eligibility criteria”, but that help our guests understand the reality of being on a wilderness river trip.
Our primary goal is to minimize the risks associated with adventure trips in a wilderness environment. The trip involves physical exertion and exposure to the elements, including cold water and the potential for heat, sun, wind, rain and snow. We have experience accommodating people with a wide range of physical disabilities and/or health conditions. However, individuals who are overweight, lack conditioning, or have other physical limitations or ailments that interfere with the realistic encounters on a wilderness river can endanger themselves, other guests, and the guides. Please consult your doctor if you have medical or health conditions that could impact your ability to participate in this outdoor adventure.
It is very important that each trip participant take an active role in their own safety. You will likely encounter wilderness conditions that you are unfamiliar with, and those conditions may change rapidly. It is critical to pay attention at all times, to be aware of your surroundings, and to avoid taking unnecessary risks. Even a non-life threatening injury in a wilderness setting can become a major emergency for you, and can endanger the entire group. Swimming alone or hiking alone is discouraged. Excessive alcohol consumption or illicit drug use is not tolerated. Using common sense, and following both the explicit instruction and the lead of your guides can go a long way towards keeping yourself and the group safe. Some obvious things to avoid in camp and on shore (by way of example) are: walking around without shoes in camp, approaching wild animals, not paying attention to what is above or around your tent site that could harm you, not paying attention to hazards such as poison ivy and rattlesnakes, and walking near precipitous ledges.
River trips, particularly those involving whitewater, are inherently risky. While the risk of a trip is part of what makes it an exciting adventure, you must be entirely respectful of the risk that such a trip poses. It is important that you are confident in your swimming ability, and your ability to stay calm in the event you become a non-voluntary swimmer. Your odds of becoming a non-voluntary swimmer change with the classification of a rapid, boat selection and environmental factors. On class IV and greater whitewater, the probability that you will become a non-voluntary swimmer is significant. A swim in whitewater is much more difficult and physically draining than swimming in flat water. Swimming in cold water can cause a gasping effect on your respiratory system. This can be overcome by focusing on your breathing and calming yourself down. Swimming in cold water will also much more quickly sap your energy and decrease muscle function than swimming in warmer water. While our guides are highly trained and will do their absolute best to rescue you, a successful rescue is greatly hampered by a swimmer who is unprepared for a swim in whitewater, who fails to actively participate in their own rescue, and who is not able to follow directions while under stress. You will receive a detailed orientation talk at the start of your river trip, but you can get a better idea of what to expect by watching a version of an orientation talk here: http://www.oars.com/videos/oars-whitewater-orientation.
Due to the physical nature of this trip, we highly recommend that you engage in regular exercise for at least three months prior to departure to ensure preparedness. No gym membership required! Simple exercises like push-ups, sit-ups and squats go a long way to improving core fitness. Start with these exercises and do three sets of ten repetitions each, three to four times per week. Aerobic training is also easy to accomplish without expensive equipment. Take 30 – 40 minutes two to three times a week and go for a brisk walk, easy jog or bike ride around town. If you have access to a pool, lake or the ocean, swimming is obviously an ideal choice for aerobic exercise. It provides a full-body workout and is training that is useful in the event of an involuntary swim in a whitewater rapid. It is important to push yourself in the months leading up to your trip by increasing your strength training repetitions and the pace of your aerobic training. Check with your doctor prior to beginning any exercise program to be sure you are medically safe to participate. Starting an exercise program that is more strenuous than you are ready for may result in injury or risk exacerbating existing health conditions. Getting in shape will certainly add to your enjoyment of the trip.
What To Bring
Click on this link for helpful information about packing for your trip: https://www.oars.com/video/wear-bring-one-day-rafting-trip-oars/
The information below is subject to when your trip takes place. The need for warm weather or cold weather items should be based on a reliable weather forecast leading up to your trip.
The best choice is an amphibious shoe that drains water, protects your toes and won’t come off in swirling current. A retired pair of athletic shoes can work well, too. Sport sandals with a heel strap are a good option. Find professional-grade options made by Chaco®, the official footwear sponsor of OARS guides.
We recommend starting with bathing suit/swim trunks and a lightweight synthetic shirt. For cool weather, add layers of synthetic long underwear and warmer clothes as needed.
Protecting yourself from the sun should be taken very seriously. A hat, sunscreen, lip balm and sunglasses are a must. In many cases, a long-sleeve shirt and/or light-weight pants are the best method for preventing sunburn.
☐ Sunscreen & lip protection; waterproof and SPF 30 or higher
☐ Water bottle
☐ Shade hat/visor, flexible enough to wear under your helmet
☐ Sunglasses (preferably polarized) with securing strap
☐ Swimsuit; a two-piece is recommended for women for changing and using the restroom

- ALWAYS BE PREPARED FOR CHANGING WEATHER! Especially during the months of April, May and early June, California can experience extreme changes in weather.
- Wearing cotton items on a river trip is only appropriate when the weather is hot. Wet cotton will chill your body temperature.
- Our wetsuits do not include “wetsuit booties”–please bring your own, or wear wool socks with tennis shoes as a good alternative.
Please let us know if you have any medical issues or dietary restrictions that well need to consider in planning your trip.
We provide one small, shared waterproof bag (approximate sealed size: 17” tall x 9” diameter) per raft to hold your camera and other items you might need during the day. While these bags are designed to be waterproof, you may wish to place your camera in a zip-lock plastic bag or waterproof casing for additional protection. Disposable waterproof and panorama cameras are also a fun option.
There are often professional companies taking photos of each raft at some of the Tuolumne’s larger rapids, which provide great action shots. These companies are not affiliated with OARS You will need to contact them separately to purchase these pictures. ‘Picture This…Rapid Shooter’ is one such company; visit them at http://www.rapidshooter.net after your river trip. Their phone number is (209) 379-2267. (To see your photos online, you must email ‘Picture This…Rapid Shooter’ and request that the photos from your trip be posted to their website.)
Each participant will need to complete the required trip forms online and submit them no later than 30 days prior to your trip, or immediately if booking within 30 days.
Final payment is due in our office 60 days prior to your trip. Please let us know if you would like us to automatically charge your credit card on file when payment is due.
We recommend that you leave your valuables at home or in your private vehicle and take on the river only what’s absolutely necessary. We also recommend you leave dry shoes and clothing in your car to ensure a comfortable drive home.
Tipping is optional, but appreciated by our staff. If you are wondering how much to tip, you may consider that we operate in a service industry with a host of behind-the-scenes contributors in addition to the guides on your trip. In general, we suggest a gratuity based on 10 – 15% of the trip cost. It is customary on OARS trips for gratuities to be given to the Trip Leader in the form of cash or personal check, who will then distribute appropriately amongst all the guides and support staff.
In reviewing your statement, you’ll note a $1/person/day donation to Tuolumne River Trust, a non-profit conservation organization dedicated to protecting the Tuolumne River through education, restoration projects and the advocacy for a healthy watershed.
