The Rio Grande pours out of the Box Canyon below Rio Grande Reservoir into a broad open valley, then flows for miles, flowing its way towards Creede. From there it picks up speed and hustles past the scenic Palisades on the way to the little burg of South Fork. In between it grows some big trout and in good numbers, enough to warrant Gold Medal water status from the state.

The grassy riverbanks in the Coller State Wildlife Area attract elk, deer and moose in winter. You can see bighorn sheep throughout the year on the south-facing Palisade cliffs extending from the Coller State Wildlife Area to Wagon Wheel Gap. At the gap, golden eagles soar above the cliff faces and fish the Rio Grande.

The Coller State Wildlife Area above South Fork is a great example of management in the public interest. The water is great for for wading fly fishers who enjoy boulders and structure. There are numerous excellent access points near bridges with riverside parking areas, with different sections being suited to varying water levels and fishing styles.

Best Time to Fish: Between March and May – You’ll find some good springtime walk-wades and floats… and have the river all to yourself. It’s best to catch it now because during the summer, the Rio Grande becomes a popular destination fishery.
