We are a non-profit corporation, founded in 1963, registered with the State of California and known to one and all as ARTA.Our mission is to introduce you to the wilderness and to involve you in our trips in a manner that is safe, meaningful, and beneficial to both you and the environment.



At the heart of the organization is our staff of incredible river guides. United by a passion for wild places and by a belief that a river trip should be more than a Disneyland ride, they provide exceptional service and outstanding camaraderie. They will be your porter, escort, captain, cook, guide and interpreter, but most importantly, they will be your friend.



Our non-profit status and philosophy ensure that any surplus revenues generated by our trips are reinvested in the company or donated to conservation organizations and are not distributed to individuals or investors. Your participation helps protect our nation's wild rivers for future generations to enjoy.We are proud to be recreation service partners with the National Park Service, the U.S. Forest Service and the Bureau of Land Management. We operate under Special Use Permits granted to us by the Stanislaus, Klamath, Siskiyou, Bitterroot, Salmon and Challis National Forests, the Folsom, Medford and Moab Districts of the BLM, and under a concessions contract at Dinosaur National Monument. ARTA is an equal opportunity service provider and all trips are operated on a non-discriminatory basis
