Cowiche Canyon Trail System | Yakima

Cowiche Canyon Trail System, located just a few miles southwest of Yakima, Washington, is a remarkable natural and recreational area that encompasses nearly 900 acres of diverse landscapes, ranging from riparian creek corridors to shrub-steppe uplands. This trail system is managed by the Bureau of Land Management (BLM) in collaboration with the Cowiche Canyon Conservancy, a local nonprofit dedicated to preserving the canyon’s unique ecology and promoting sustainable public access. The area is open year-round for non-motorized outdoor activities such as hiking, mountain biking, birdwatching, and cross-country skiing.

Geography and Setting

The Cowiche Canyon itself is a scenic, narrow canyon carved by Cowiche Creek as it flows through basalt formations typical of Central Washington’s geological makeup. The landscape transitions dramatically from lush riparian zones along the creek, with cottonwoods, willows, and a variety of wetland plants, to the drier, open shrub-steppe uplands, dominated by sagebrush, bitterbrush, and native grasses. This variation supports an impressive range of flora and fauna, making the canyon a biodiversity hotspot within the Yakima Valley.

Trail Network and Features

The Cowiche Canyon Trail System offers approximately 13 miles of interconnected trails catering to a wide spectrum of outdoor enthusiasts:

Cowiche Canyon Trail (2.9 miles)
This trail follows an old railroad grade along the creek, providing gentle slopes ideal for family hikes and easy mountain biking. It includes 11 bridge crossings over Cowiche Creek and meanders through lush riparian habitats. The trail is particularly popular for winter cross-country skiing and snowshoeing due to its relatively flat terrain and scenic views.

Cowiche Canyon Uplands Loop (3.3 miles)
This loop trail climbs into the upland areas above the canyon floor, offering panoramic views of the canyon, Yakima city, and Mount Adams. The uplands trail features more challenging terrain with some elevation gain and is accessible to hikers, mountain bikers, and horseback riders.

Wilridge Winery Trail (3.9 miles round trip)
This trail extends from the uplands area to Wilridge Winery, making it a popular option for those who want to combine outdoor recreation with wine tasting. The route showcases the canyon’s diverse ecosystems and opens up into vineyard landscapes near the winery.

Other smaller connector trails and spur routes enable visitors to customize their hike or ride length and explore different parts of the canyon and uplands.

Ecology and Wildlife

Cowiche Canyon’s ecological diversity is one of its greatest assets:

Flora: More than 185 species of native plants have been documented, including wildflowers such as balsamroot, lupine, and Indian paintbrush, which provide vibrant spring and summer colors. The creek corridor supports dense vegetation of willows, dogwoods, and other moisture-loving plants.

Fauna: The area supports at least 125 bird species, making it a prime destination for birdwatchers. Common sightings include red-tailed hawks, great horned owls, western bluebirds, and a variety of waterfowl and songbirds. Mammals such as mule deer, coyotes, and bobcats also inhabit the canyon.

Riparian Habitat: The creek and its wetlands serve as an important refuge for amphibians and aquatic insects, contributing to the overall health of the Yakima River basin ecosystem.

Access and Facilities

The Cowiche Canyon Trail System can be accessed via four primary trailheads:

Weikel Trailhead: The main access point for the Cowiche Canyon Trail along the creek. It offers parking and informational kiosks.

Summitview Trailhead: Provides access to the uplands loop with parking and trail information.

Scenic Trailhead: Another entry point into the uplands area, often used for longer hikes and bike rides.

Powerhouse Road Trailhead: Located near the canyon mouth, this trailhead connects to the Cowiche Canyon Trail.

Parking is available at each trailhead, but facilities are minimal, with no restrooms or water sources on-site. Visitors are advised to bring sufficient water and plan accordingly.

The trail system is designated for day-use only; camping, fires, and motorized vehicles are prohibited to protect the natural environment.

There are no entrance fees, making it an accessible recreation spot for locals and tourists alike.

Visitors are encouraged to keep dogs on leashes and clean up after pets to minimize wildlife disturbances.

Poison ivy is prevalent along the creek corridor, so caution is advised to avoid contact.

The trail system operates on a leave-no-trace ethic, emphasizing the protection of sensitive habitats and minimizing human impact.

Seasonal Highlights and Recreational Activities

Spring and Summer: Wildflowers bloom profusely, attracting photographers and botanists. The warmer weather is ideal for hiking, mountain biking, and birdwatching.

Winter: The Cowiche Canyon Trail is frequently used for cross-country skiing and snowshoeing, with its flat, well-maintained paths and scenic creek views.

Community and Conservation Efforts

The Cowiche Canyon Conservancy plays a critical role in trail maintenance, habitat restoration, and educational outreach. Volunteers regularly engage in invasive species removal, native plant restoration, and trail improvements to ensure the canyon remains a thriving ecological and recreational resource. Their partnership with BLM has allowed the expansion of trail access and protection of key wildlife corridors.
