Klamath River, Oregon/California
Flowing 257 miles through Oregon and northern California into the Pacific Ocean, the Klamath River is the second largest river in California. Though the upper basin is used for farming and ranching, most of the lower basin remains wild. This river spouts long stretches of Class I-II whitewater rapids (covering over 100 miles) while some narrower stretches have Class III to IV rapids. This makes it a great place for whitewater rafting, sports fishing, kayaking, and other recreational activities you can enjoy on a trip to the Klamath River.
Rio Grande River, Texas
The Rio Grande River forms the border between Texas and Mexico. With a total length of 889 miles to 1,248 miles, it originates from south-central Colorado, descending across steppes to water-rich agricultural regions as it flows into the Gulf of Mexico. The water of the Rio Grande is dammed for irrigation, supplying more than 850,000 hectares of cropland and its basin produces a significant amount of electricity. This wild river is considered one of the leading industries for agriculture, mining, and recreation in the United States.
White Salmon River, Washington
The lower stretches of the White Salmon River between Gilmer Creek and Buck Creek were designated as Wild and Scenic before the upper river between the headwaters and the boundary of the Gifford Pinchot National Forest. Stretching over a total span of 44 miles, this river is used for whitewater boating all year round. Visitors are drawn to the clear blue water, continuous rapids, waterfalls, unique fishes, and a vibrant plant ecosystem. The river has class III-IV whitewater rapids which may sometimes abruptly drop to about 50 feet per mile – a challenge to even boaters with very advanced skills.
Rogue River, Oregon
One of the original eight rivers to receive a designation in the Wild and Scenic Rivers Act of 1968 is the Rogue River located in southwestern Oregon. This river runs about 215 miles, flowing westwards from the Cascade Range into the Pacific Ocean at Gold Beach. People have inhabited the shores of the Rogue River and its tributaries for at least 8,500 years. Flowing largely through forests, (including national forests) and with high biodiversity, you will find many public parks, hiking trails, and campgrounds near the Rogue River. Most of the basin is dominated by temperate and coniferous forests and many plant and animal species.

Illinois River, Oregon
Located in Curry County, Oregon, the Illinois River is a tributary of the Rogue River in Oregon. It is about 56 miles (90km) long, draining part of the Klamath Mountains in northern California and southwestern Oregon. This river is well known by lovers of rafting and kayaking because it offers great whitewater, amazing scenery, rich biodiversity, abundant fishes, and plenty of fascinating recreational activities for campers. However, taking a trip to the Wild sections of the Illinois river (Briggs Creek and Nancy Creek) requires a permit from the U.S Forest Service. This wild section features highly technical class IV to IV + whitewater rapids – which is why the Illinois River is popularly considered to be “a wilderness river that tests both the skill and strength of boaters.” You’ll want to be careful around the river if you’re not very experienced.
