The Troutmap for the Trinity River covers two sections: the 63.8 river miles from Lewiston Dam to Cedar Flat Bridge, and the 49.0 river miles from Cedar Flat Bridge to the Klamath River. The second section contains a number of dangerous rapids, and should only be floated by experienced kayackers, rafters, or with a professional guide. This is a river of varying character, with good access, and famous for both trout and steelhead.
