Hiking Trails in Colusa County, California: Complete Trail Guide
Colusa County is flat Sacramento Valley farmland at first glance, but those searching for Hiking Trails in Colusa County will find it holds one of the best waterfowl-viewing wetland trails in the entire Pacific Flyway and a Coast Range canyon hike just across the Yolo border. I’ve spent four-plus years cataloging trails across this state, and Colusa County is exactly the kind of place most hikers drive past without realizing there’s anything here, which is part of why the Sacramento National Wildlife Refuge in particular rewards the detour, especially during peak waterfowl season when the scale of the migration is hard to describe without seeing it firsthand. This guide covers the county’s three real hiking destinations.

Key takeaways:
- Colusa County’s hiking centers on three spots: Sacramento National Wildlife Refuge, Cache Creek Canyon on the Yolo border, and Stony Gorge Reservoir near the Glenn County line.
- Sacramento NWR hosts hundreds of thousands of migrating ducks and geese every winter, with peak viewing October through February.
- The refuge is not entirely free; a nominal entrance and parking fee applies via a self-pay kiosk.
- Cache Creek’s Redbud Trail delivers a dramatic magenta wildflower bloom every February and March, free with no permit required.
- Stony Gorge Reservoir offers a quiet, low-key 2-mile shoreline trail with an easy $5 day-use fee.
Hiking in Colusa County: Sacramento Valley wildlife and Cache Creek trails
Colusa County is predominantly flat agricultural land, but it holds two notable natural hiking areas: Sacramento National Wildlife Refuge, one of the premier waterfowl-viewing destinations on the entire Pacific Flyway, and Cache Creek Canyon Regional Park, straddling the Yolo/Colusa border where the Coast Range foothills begin.
Stony Gorge Reservoir, on the Colusa/Tehama county border near Orland, rounds out the county’s short list of real trail destinations. None of these three require a long detour if you’re already passing through on I-5 or Highway 20, which makes Colusa County an easy add-on to a longer Sacramento Valley or NorCal road trip rather than a destination worth planning an entire trip around on its own.
Best nature trails at Sacramento National Wildlife Refuge, Colusa County
Sacramento NWR protects about 10,800 acres near Willows, anchoring the Sacramento NWR Complex and serving as one of the most important wintering grounds for migratory waterfowl in the entire Central Valley.
A 6-mile auto tour loop lets visitors view wetlands from their vehicle, with a few designated stops where you can get out and stretch, worth doing in addition to the walking trail, since it covers ground the Wetland Walk alone doesn’t reach.
Wetland Walk at Sacramento NWR: Colusa County’s best nature trail
This flat boardwalk-and-gravel trail system, roughly 1.6 to 2 miles total across its north and south loops, departs directly from the Visitor Center and winds through wetland ponds and tule marsh, with interpretive panels explaining the Pacific Flyway migration the refuge exists to support.
October through February brings the real spectacle, tundra swans, snow geese, and pintails in numbers that can run into the hundreds of thousands, occasionally exceeding a million combined across the refuge complex on a strong migration year, with the sound and sight of that many birds lifting off at once hard to convey secondhand.
Spring brings a quieter payoff instead: American bitterns and white-faced ibis are both realistic sightings, though the crowds and dramatic scale of winter give way to something calmer and more solitary. The north loop is wheelchair accessible. A day-use entrance pass is required for the refuge’s Auto Tour, available via self-pay kiosk (cash or card) or in advance online, though the Wetland Walk trail itself is fee-free.
Best hiking trails at Cache Creek Canyon Regional Park, Colusa County
Straddling the Yolo/Colusa border adjacent to roughly 70,000 acres of BLM Cache Creek Wilderness, this park offers Coast Range canyon hiking, a real change of terrain from the flat valley floor most of the rest of the county sits on.
Redbud Trail at Cache Creek: Colusa County’s best wildflower canyon hike
At 9 miles round-trip from the Judge Davis trailhead off Highway 16, this trail follows Cache Creek canyon through Coast Range serpentine terrain, with western redbud trees blooming vivid magenta on bare branches every February and March, a striking display against the still-dormant canyon, and one of the better wildflower-season hikes in this part of the state for anyone who doesn’t want to drive all the way to the coast or Sierra foothills for a spring bloom.
Tule elk are occasionally visible in the Cache Creek Wildlife Area to the north. Access is free through the BLM with no permit required, but this is real rattlesnake habitat from spring through fall, so watch your footing and hand placement carefully around rocks and brush.
Stony Gorge Reservoir: Colusa County’s best reservoir hiking
Managed by the Bureau of Reclamation near Orland on the Colusa/Glenn border, Stony Gorge offers a straightforward 2-mile shoreline trail combined with bass fishing access and a small picnic area, a low-key, uncrowded stop rather than a destination hike in its own right.
Oak-covered hills around the reservoir bring a real early-spring wildflower display, and a $5 day-use fee covers both the trail and the boat launch. It’s accessible year-round and rarely crowded, even on weekends.
