The Tuolumne River in California carves through Sierra Nevada granite and oak foothills, offering world-class whitewater, fishing, and sweeping canyon scenery.
The Tuolumne River traces a dramatic 149-mile arc from its headwaters near Tuolumne Meadows, across the western slope of the Sierra Nevada, and into the San Joaquin Valley. For centuries the river sustained the native Miwok people, who fished its banks and traveled its corridors through the mountains. Gold rush prospectors later worked its gravel bars, and the river's name itself echoes a Miwok word recorded by early Spanish missionaries.
The crown jewel for adventure seekers is the Main Tuolumne Canyon, an 18-mile wilderness run widely regarded as one of the finest rafting trips in North America. Rapids with names like Clavey Falls and Gray Rocks demand respect, yet the pools between them invite quiet reflection beneath sheer canyon walls. Guided fishing charters operate on calmer lower sections, targeting wild trout in clear, cold water.
Upstream, the river flows through Tuolumne Meadows, a high-elevation subalpine valley that draws hikers and photographers throughout summer. Downstream, Hetch Hetchy Reservoir stores the river's water for the San Francisco Bay Area, and the reservoir rim trail reveals stunning cliffs and seasonal waterfalls.
The Tuolumne River rewards those who seek it out with scenery and solitude that few California waterways can match.
Visit in late spring when snowmelt swells the current and the canyon walls are streaked with temporary waterfalls.
Try the stretch near Groveland for some of the most accessible and scenic whitewater runs on the river.
Bring a valid California fishing license if you plan to cast for rainbow or brown trout in the upper reaches.
Pack layers even in summer, as temperatures in the canyon can swing dramatically between midday and evening.
Arrive at put-in points early on weekends, as popular launch sites fill quickly during peak rafting season.
