Superb Rafting Adventures Since 1977

Welcome to our 43rd year of offering the finest outdoor experience possible on the American River. In 1977 EarthTrek Expeditions opened its doors for the first time as an adventure travel agency offering a full array of worldwide expeditions, treks and adventures. In our early years we operated ski bus tours to Mammoth and Utah, bicycle tours throughout California and the Southwest but whitewater rafting became our most popular and favorite activity so we decided to make this our specialty. From those roots we grew to become one of the largest and most respected outfitters on the American River. In 2016 we teamed up with O.A.R.S., one of the most respected raft companies in the country, to take over the operation of our river trips while we concentrate on making the camping portion of your trip the very best. 

EarthTrek only offers rafting trips on the South Fork American, Middle Fork American and North Fork American Rivers. If you are interested in rafting other rivers in California, the Grand Canyon, and other western states, check out our
Links page where we can direct you to many other outstanding outfitters offering trips on these rivers.

We know how valuable your vacation and recreation time is so we encourage you to carefully check us out and compare our services with other rafting companies. We are confident that you will appreciate the commitment and attention we put into making a rafting trip on the American River with EarthTrek Expeditions the very best.



The South Fork of the American River in its natural state would not have sufficient flows during the summer to support rafting or other floating activities as they are known today. Adequate flows for rafting result from hydroelectric releases from facilities located at Chili Bar and above. These releases are made for power generation and are not subject to the control of El Dorado County or commercial rafting companies operating under permits from El Dorado County.”
