From Carbon River Entrance, the old road, now the Carbon River Trail, runs about 3.5 miles to Chenuis Falls Trailhead. The old road grade keeps the approach gradual, and bikes are allowed as far as the trailhead, where there's a rack. From there, continue on foot across the broad rocky riverbed and the log footbridge; cairns sometimes mark the way. The bridge often washes out in winter. Never cross the Carbon River if the bridge is missing, and check park access and trail conditions before setting out. Pets aren't allowed. At the trailhead, you'll find a restroom and picnic table, but no potable water.
