Smith River National Recreation Area is located northwestern California, United States. The Smith River National Recreation Area is in Six Rivers National Forest and is managed by the U.S. Forest Service, an agency of the U.S. Department of Agriculture. Created by Congress in 1990, Smith River National Recreation Area forms a northern border to Redwood National and State Parks. The Coast Ranges and the Smith River, the longest National Wild and Scenic River in the U.S., offer a variety of recreational opportunities. The recreation area is considered one of the best fishing regions in the U.S., with trophy sized steelhead, chinook salmon and other game fish species. Smith River National Recreation Area has five campgrounds located near major streams and along the Smith River. Rafting is popular in the summer months and most hiking trails are accessible year-round, but both activities may be greatly affected by heavy rain that swells creeks and rivers. The region receives over 90 inches (230 cm) of rainfall annually, with the greatest amounts in the winter. Summers may be foggy as moisture laden clouds rise up the Coast Range mountains from the Pacific Ocean.
