If you find yourself on anything other than an obvious well worn tread, you are likely on one of many use trails that follow along sections of the river. In that case, I suggest you back track until you are on the established tread, then proceed with eyes peeled. The river was low enough to make the dozen or so crossings fairly easy rock hopping affairs. The trail usually crosses at wide fords to facilitate horse crossings, so hikers who want to keep their feet dry need to mosey up or down stream a bit to find some accommodating rocks and boulders. The use trail network along the river usually accommodates this effort.
Signage is good all along the way.
At the junction with the Big Pines trail the signs are so new that that invasive species, Homo sapiens var. There is also good signage at the Miller Canyon Trail junction and all of the official Forest Service camps along the way are identified with signs. The autumn colors were spectacular. Big leaf maples and the Black Oaks were showing lots of brilliant yellow and the Poison Oak was carmine, orange and fluorescent pink. There is also colorful fruit on the madrone, toyon, coffee berry and holly leafed cherry.
