The beautiful American River is the site of California's 1849 Gold rush and now is the most popular whitewater rafting river in the Western US... let us show you why! One of the few rivers in California to have adequate water flows year round for rafting, The South Fork of the American River is a wonderfully fun guided rafting adventure for first timers, families and groups. The class 3 rapids are perfect for all types of participants, lots of action but not too intense for novices. Half, one and two day trips are available.
