Allow about 11 hours for the full return. The mapped profile rises from about 1,442 metres at the access to 2,248 metres near the pass, with roughly 985 metres of sampled cumulative ascent; that is not the same as simply subtracting the endpoints. The canyon pavement and boardwalks become rooty, rocky singletrack beyond Upper Falls, and the final climb is sustained. Beyond the busy front section this is backcountry travel: carry navigation, be ready for stream crossings, treat water, and carry bear spray. Dogs should stay leashed and under control.
