Terms & Conditions

Trip Preparation

On a Desert Adventures guided trip, we supply all meals and equipment along with knowledgeable, experienced guides. Tents are provided based on double occupancy; single tents are available upon request at an additional charge.  Sleeping bags, liners, pads, and pillows are also included in your trip cost.  We take care of the details so all you need to pack is your personal gear and an adventurous spirit.

Our outdoor adventures are active participatory trips.  Most of our backpacking, kayaking, biking and multi-sport itineraries are suitable for reasonably fit first-timers.  It is your responsibility to understand the rigors of the trip and to represent to us that you are physically capable of participation.  You understand your own health and fitness better than anyone and we will rely on you to provide accurate health information on your registration form.   A combination of cardiovascular and resistance training exercises before your trip will help ensure preparedness for an outdoor adventure and will certainly add to your overall enjoyment. If you have any medical conditions that might impact your ability to safely participate, we encourage you to check with your doctor before you reserve your trip.

To increase your safety, we expect everyone to watch our 23-minute Whitewater Orientation video before joining us.  Watch at or call 800-346-6277 to request a free DVD.  Please don’t leave home without watching.

Be sure to let us know if you will have a birthday or anniversary during your trip.  We need to know as soon as possible about any dietary requirements we should consider in planning your trip.  If you have food allergies or restrictions, we will do our best to accommodate your needs.  However, people with severe food allergies may need to supply some or all of their own food since we can’t entirely mitigate the risk of cross contamination*. Additionally, some specific needs can only be met if we charge you a supplemental menu fee to cover our increased costs.

*Note: Pending a detailed discussion about a guest’s specific dietary requirements, OARS may determine that a severely allergic person is not suitable for our adventures due to the constraints of preparing food for groups of people in a wilderness setting.

Permitting Agencies

We are proud to hold permits with various state and federal agencies charged with protecting wilderness areas, allowing us to conduct trips on protected land and water that might otherwise be inaccessible to members of the general public.  We are an authorized concessioner in Grand Canyon National Park, Dinosaur National Monument, Canyonlands National Park and operate by special permit in Yosemite National Park.

In Idaho, O.A.R.S. Dories, Inc. is a licensed and bonded outfitter and our guides are licensed by the state.  On the Middle Fork of the Salmon River and the Main Salmon River we operate under special use permit in the Salmon-Challis National Forest.

We operate our Gorges of the Lower Salmon trips under authorization from the Bureau of Land Management: Cottonwood District.

In Oregon, O.A.R.S.

Ancestral Lands Acknowledgements

We respect and recognize that many of the river canyons, national forests, BLM and state lands, as well as national parks where we operate are the ancestral homes of many indigenous communities.

  • In Idaho, we acknowledge the traditional territories of the Lemhi-Shoshone, Nez Perce and various bands of the Shoshone-Bannock along the Salmon River, as well as the Coeur d’Alene tribe of the Snake River through Hells Canyon.

  • In Oregon, along the Owyhee, we acknowledge the Northern Paiute and Shoshone-Bannock tribes, as well as the territories of the Tolowa Dee-ni’ and Confederated Tribes of Siletz Indians, which includes bands of the Tutuni and Takelma, along the Lower Rogue River.

  • In California, where we operate along the Klamath, American, Tuolumne, Stanislaus and Merced Rivers, we acknowledge the territories of the Shasta, Yokuts, Nisenan, Karuk and various bands of the Sierra Me-wuk/Miwok tribes.

  • In Arizona, where we run Grand Canyon trips, we recognize the native lands of the Diné, Hopi, Zuni, Hualapai, Havasupai, and Paiute tribes.

  • In Utah, we acknowledge various bands of the Ute, as well as the Eastern Shoshone, Diné, Pueblos, Hopi, Havasupai, Hualapai, and Southern Paiute whose traditional territories include stretches of the San Juan River, Colorado River, Green and Yampa Rivers where we operate.


It is our intention to accurately acknowledge the indigenous groups who have and continue to occupy the lands where we operate throughout the Western U.S., but if any of this information is incorrect, please let us know so we can fix our errors.




All prices are in U.S. Dollars.  Prices for trips in National Park units are subject to National Park Service final approval. Prices are valid at the time of printing and may change without notice. You can always find the most current prices on our website or by calling us.

Cancellations and Refunds

Please understand that our trip dates and capacities are limited by the managing agencies, and when we accept your reservation, we may be turning others away from booking that trip.  If you find it necessary to cancel your trip, please notify us as soon as possible. You can telephone, but we also need a written notice. Cancellation penalties can range up to 100% of the trip cost, depending on the date and particular trip on which you’ve been holding spaces. We regret we cannot make exceptions for personal emergencies. For this reason, we strongly urge you to purchase a travel protection plan (see “Travel Protection” below). If you have any questions regarding our cancellation policy for a specific trip, please consult your pre-trip materials or contact one of our Adventure Consultants.

Transfer Fee

You may transfer from one trip to another during the same season for a nominal administrative fee. Transfers on multi-day trips that are requested after full payment is due will be treated as cancellations.  Transfer fee policies are most stringent on Grand Canyon and Middle Fork Salmon trips and those run by affiliate companies.


Please visit to review our essential eligibility criteria. Weight restrictions may apply, particularly during periods of high water when the probabilities for non-voluntary swims are increased.  More strenuous trips require higher levels of physical fitness.  People who are obese, pregnant, have heart trouble or other medical conditions should have their physician’s approval before joining an OARS trip.  People with disabilities are welcome, pending an advance discussion of all special requirements.

The trip leader has the right to disqualify a guest at any time during the trip, or at the pre-trip meeting, if she or he feels the guest is physically or mentally incapable of participation or if the guest continuing on the trip will jeopardize the safety of the individual involved or the group.  Refunds are not available under such circumstances.

Travel Protection

Although our intention is for a safe trip for all, we strongly recommend that you help protect yourself, your belongings, and your vacation through the purchase of an optional travel protection plan. For multi-day adventures, OARS strongly recommends a travel protection plan that includes trip cancellation and interruption coverage, baggage loss protection, emergency medical and emergency medical evacuation coverage. A travel protection plan may help reimburse the cost of your pre-paid, non-refundable payments in the event you are prevented from taking your trip for a covered reason. Trip participants should realize that in the event of illness or injury on a wilderness trip, evacuation can be prolonged, difficult and expensive. Baggage and cameras are carried entirely at the owner’s risk, and we accept no responsibility for lost, damaged or delayed property. For complete details and to purchase a plan we highly recommend, visit:

Trip Forms

All participants are required to complete their registration forms and sign a standard liability waiver or assumption of risk before the trip, acknowledging awareness and acceptance of some risks associated with adventure travel.

Foreign Travel

Our international trips are operated by independent suppliers arranged through O.A.R.S. International, Inc. We have no right to control their operations and therefore make the described travel arrangements upon the express condition that O.A.R.S. Companies, Inc., its subsidiaries, agents and employees, shall not be liable for any delay, mishap, inconvenience, expense, irregularity, bodily injury or death to person, or damage to property occasioned through the conduct or fault of any company or individual engaged in providing these services.  Proof of medical evacuation insurance is required for all of our international adventures.

Responsibility – An Important Notice

Payment of your deposit represents your acceptance of the following conditions:  O.A.R.S. Companies, Inc., its subsidiaries and cooperating agencies act only in the capacity of agents for the participants in all matters relating to transportation and/or all other related travel services, and assume no responsibility for injury, loss or damage to person or property, however caused, in connection with any service, including, but not limited to that resulting directly or indirectly from acts of God, detention, annoyance, delays and expenses arising from quarantine, strikes, theft, pilferage, force majeure, failure of any means of conveyance to arrive or depart as scheduled, civil disturbances, government restrictions or regulations, and discrepancies or changes in transit over which we have no control. Reasonable changes in itinerary may be made where deemed advisable for the comfort and well-being of the participants, including cancellation due to water fluctuation, insufficient bookings, and other factors. Prices and dates subject to change without notice.

OARS trips occur in areas where unpredictable environmental conditions are to be expected.  To avoid dangerous situations for our guests and guides, it is important that all travelers obey the rules and regulations as determined by the managing agencies and the Trip Leader and demonstrate reasonable consideration for other guests and OARS employees.  We reserve the right to remove any guest from a trip if, in our opinion, that guest’s actions or behaviors pose a threat to the safety of her/himself or others, or if those actions or behaviors compromise the enjoyment of the trip for others.  Should a guest be asked to leave a trip, there will be no refund for the unused portion, nor will OARS be responsible for additional expenses incurred by the guest for accommodations, return transport, change fees, etc.


Our guides work very hard to please you and provide an excellent experience. They appreciate whatever feedback you care to give them, including a gratuity if you so desire.

Guide Requests

OARS is proud of the fact that we can sometimes bring clients together with their favorite guides. However, guide requests are often not possible and cannot be guaranteed for a variety of reasons. We will do everything we can to schedule you with the guide you have requested, but in the end, please understand that accommodating your request may not be feasible.
