My brother said the route would be a first class river walk. It is that! You can either pick it up out of the campground at Lower Falls or from the Curley Falls trailhead. Doesn't matter as once you get going you are going to be something on the order of an ant working your way through the lawn in your backyard. Old growth trees the magnitude of which are hard to come by! Vine maples that are a lot more like towering oaks. Some places the moss is so thick hanging from everything you are sure you're on the Hoh River Trail in the Olympics! Most of the time the river is right along side. If you do leave it, you will come back to it in fairly short order. The blow downs have been cut through. The few you will find that haven't are certainly navigable. The route is open to mountain bikes, but not so overtly rutted that it's ruined. Muddy in a couple spots, steep a couple more, down to a rocky gravel trek here and there. We made excellent time as this isn't a total up hill burner. Bolt camp, 2 1/2 miles from Curly parking lot comes up rather soon. There are spots where others have side cut down to gravel bars by the river. We took advantage of a couple of those. Once out on the bar, you're really looking at boulder bars! Massive amounts of sediment from a fabulous river. A couple deer wondered down to rivers edge. Songbirds and woodpeckers joined in. You can make this as long a walk as you want to enjoy. Deep within the trees, it works to stay out of the direct sun or probably aids in staying out of a rain soaker down pour. We went in by ourselves and only encountered 2 different mountain bikers on the way out. Talk about your independence indeed!
