Yellow Banks Park in Pleasant Hill has a nice 2.2 mile loop that was fun to hike today. We parked in the far south parking lot by the Yellow Banks Pond, where there is a vault restroom. Just south of the lake is the trailhead. Look for a bridge and a sign with trail marker #7 at the top. It's an easy loop to follow, the only part I don't like is that you have to walk on the road for a bit toward the end.
