Zephyr Whitewater specializes in California whitewater river rafting trips, and we have done so since 1973.  We run four rivers and are confident that you will not find a finer rafting trip experience anywhere.  Our guides, our food, our equipment, and our desire to give our clients the best trip possible is unsurpassed!  Zephyr is the largest whitewater rafting outfitter in the Yosemite area of California (Tuolumne and Merced rivers), and our Kings river trips near Kings Canyon/Sequoia National Park just keep getting more popular each season.

Use the map below to locate your river of choice, and click on that river's name to go to that page.  For each river that we run, we have a Trip Details page, which tells you where to meet, what to bring, recommended places to stay the night before and/or after your trip, and other valuable bits of information. You may print out any of this information, including the map and driving directions.

See our 2009 Trip Start Dates page for starting dates for each river that we run.
