If you're coming from highway 193, it should be about 2.5 miles along Rock Creek Road. Be sure to measure that since there's no address. Look for the giant electrical tower, and there's a small trail sign by the road too, and you'll see the little gravel road. Down the very short well-maintained gravel road there's a small parking lot, and the trail starts right there. There's room for 3 vehicles in the parking lot, and another 3 or 4 on the street.

This will take you about 400 feet elevation difference down to the river, then back up.
