Cottonwood Canyon State Park
Oregon’s Hidden High Desert Wilderness
Cottonwood Canyon State Park is Oregon’s second-largest state park, protecting over 8,000 acres of dramatic high desert landscape in remote Sherman County. Towering basalt cliffs, deep river canyons, and rolling grasslands create a landscape that feels more like the American Southwest than the Pacific Northwest. The John Day River — one of the longest free-flowing rivers in the contiguous United States — cuts through the heart of the park, offering world-class steelhead fishing and unmatched solitude. As a certified International Dark Sky Park, Cottonwood Canyon is also one of the premier stargazing destinations in the Pacific Northwest.
Hiking Through Ancient Canyons
The park’s trail system winds through terrain shaped by millions of years of volcanic activity and river erosion. Three main trails offer different perspectives on this wild landscape.
Trail Guide
| Trail | Distance | Difficulty | Best For |
|---|---|---|---|
| Lost Corral Trail | 4.3 miles one-way | Moderate | Canyon views, wildlife (hikers, bikers, equestrians) |
| Pinnacles Trail | 4.3 miles one-way | Moderate | Basalt formations, panoramic vistas (hikers, bikers) |
| Hard Stone Trail | 1.5 miles one-way | Easy | River access, shorter exploration (foot traffic only) |
Beyond the marked trails, old unmaintained ranch roads extend into the backcountry for adventurous hikers willing to navigate without signage. Spring (April–May) is the most enchanting season for hiking, when temperatures are mild and desert wildflowers — including lupine, balsamroot, and Indian paintbrush — blanket the hillsides.
Wildlife Encounters
The park’s remote location and diverse habitats support an impressive variety of wildlife. California bighorn sheep roam the basalt cliffs — look for them on rocky outcrops at dawn and dusk. Mule deer, coyotes, golden eagles, and prairie falcons are common sightings. The river corridor supports great blue herons, kingfishers, and river otters.
John Day River: Fishing and Paddling
The John Day River flowing through Cottonwood Canyon is renowned for its wild steelhead runs (January–April) and smallmouth bass fishing (summer). As a free-flowing river with no dams, it offers an increasingly rare experience in the American West. Multi-day float trips through the canyon are popular with experienced kayakers and rafters, especially during spring runoff.
Camping Under Dark Skies
Cottonwood Canyon earned its International Dark Sky Park certification for good reason — the combination of remote location, minimal light pollution, and wide canyon vistas creates some of the best stargazing conditions in Oregon.

Visitor Information
Getting There
Cottonwood Canyon State Park is located off Highway 206 in Sherman County, approximately 30 miles south of the Columbia River Gorge and 2 hours east of Portland. The final approach follows a winding gravel road — a sedan can make it in dry conditions, but a higher-clearance vehicle is recommended.

An Oregon State Parks day-use permit is required: $5 daily or $30 annual. The park is open year-round, though summer temperatures regularly exceed 100°F — plan activities for early morning or evening.
Best Time to Visit
Spring (March–May) for wildflowers, comfortable temperatures, and steelhead fishing. Fall (September–October) offers mild weather and golden grasslands. Summer visitors should prepare for extreme heat with ample water and sun protection.
