During each day of the trip, trained guides lead groups across about 10 miles of the Klamath River. The winding waterway takes adventurers through lazy portions and intense class III and IV rapids, some of which can be ridden outside the raft. Guides occasionally pause for excursions to waterfalls, cliff jumping, or to reset a rapid’s circuit breaker. They also supply all meals, serving prepared sandwiches and cooking tasty fare such as pancakes and barbecued chicken. For overnight trips, groups sleep at permanent campsites maintained by the U.S. Forest Service.

Tents can be brought from home or supplied by Kidder Creek Rafting Trips free of charge. Tykes 3 and older can come along on the trip. Groupon buyers should inquire about the meeting location when scheduling.<p>
