Join OARS for a classic California whitewater rafting adventure on the American River near Sacramento and Lake Tahoe, the Merced or Tuolumne River near Yosemite, or the legendary Stanislaus River into Big Trees State Park. Hike the wilds of Yosemite National Park with our naturalist hiking guides, or consider a family vacation on Northern California’s family-friendly Lower Klamath River. The majority of OARS California whitewater rafting and hiking adventures are within a half-day’s journey from San Jose and the San Francisco Bay Area, Lake Tahoe, Napa Valley, and Yosemite National Park.
For trips on the American River, OARS operates the American River Outpost, which has camping, group options, and meal plans, as well as a small retail store.
