The Klickitat River is a waterway in south-central Washington state. Originating in the Cascade Range near Gilbert Peak, it flows south for approximately 95 miles before joining the Columbia River at the town of Lyle. Major tributaries include the Little Klickitat River, Summit Creek, and White Creek.

The Klickitat offers a range of paddling opportunities across several distinct sections. The upper reaches feature challenging Class II-III whitewater through a narrow canyon, with the popular Parrot's Crossing to Fish Hatchery run providing 8 miles of continuous rapids. Below the hatchery, the river widens and mellows, offering Class II-III rapids through a more open landscape down to Leidl Campground. The lower sections provide scenic Class II floating as the river approaches the Columbia. Overall difficulty ranges from Class II to V+, with the upper sections and Lyle Gorge requiring advanced whitewater skills. Most popular runs are suitable for intermediate paddlers comfortable with Class III rapids.

The river is typically run from April through July, with peak flows during spring snowmelt. Late summer and fall offer lower water suitable for beginners on easier sections.

The Klickitat flows through diverse ecosystems, transitioning from coniferous forests to oak and pine woodlands. Wildlife sightings may include deer, elk, osprey, and bald eagles. The river is renowned for its salmon and steelhead runs. Key landmarks include columnar basalt cliffs, Wonder Falls, and the historic Klickitat Trail paralleling much of the river.

Primary access points are at Parrot's Crossing, Klickitat Fish Hatchery, Leidl Campground, and various spots along Highway 142 near the towns of Klickitat and Lyle.

The river holds great cultural significance for local Native American tribes, particularly for traditional fishing practices. Today, it's valued for recreation, wildlife habitat, and as a designated Wild and Scenic River.

Safety considerations include swift currents, wood hazards, and limited cell coverage in the canyon sections. Permits are not required for private trips, but anglers need appropriate licenses. Multi-day trips are possible by combining upper and lower sections, with camping available at Leidl Campground and other designated sites. The full river offers an excellent 3-4 day wilderness float for experienced paddlers.
