The young Colorado River winds through the Kawuneeche Valley near Grand Lake

On the Grand Lake side of Rocky Mountain National Park, the Kawuneeche Valley is the quiet, green corridor where the Colorado River spends its first miles. Here the river that carves the Grand Canyon is just a clear mountain stream winding through willows and meadows. The Kawuneeche Visitor Center near Grand Lake is the gateway, and the Colorado River Trailhead, a short drive up the valley, opens the upper reaches.

This is a gentler experience than the high, dramatic country across the divide. The valley floor is broad and walkable, and it is one of the better places in the park to watch elk and moose feed in the early morning and evening. From the Colorado River Trailhead, a walk of about half a mile reaches the riverbank, and a trail of about 3.7 miles climbs to the site of Lulu City, a hopeful mining town from the 1880s that faded almost as fast as it grew. Little is left but the setting and a few traces.

A few things to plan for. This is national park land, so entry fees, park rules, and any timed-entry or reservation system apply, and those can change by year. Pets are not allowed on trails or in meadows here, so plan around that. It is also high country: weather turns quickly, and the valley floor can be wet. Stay on trails to protect the fragile meadows, which are under active restoration.
