This is one of my favorite hikes anywhere. Any time I'm in the Portland area I make sure to do at least some of this trail. Unless there are detours, the route is appropriate for most people in moderately good health. There are MANY waterfalls on this route, and it is possible to extend the hike further, emerging at Multnomah Falls. It is then a relatively short hike along the highway back to your car. (Check the maps at the trailhead or talk to a ranger for more info.)
The trails are well maintained, even in winter, and I sometimes encounter rangers on my hikes. If you manage to go on a weekday, you will likely experience little other traffic, even in summer, except near the major falls by the highway.
