The road to the falls is actually completely sealed (at least if you're coming from St Helens). There is some limited parking and a picnic area across the canyon from the falls. You can get distant views from here, but you'll have to do the short walk downhill to a bridge right at the base of the falls for a closer look. Under heavier flows that what we had seen, it can get quite misty down there. There are also a few interpretive signs to keep you busy along the way.
