The last two miles of the drive in to the trailhead is a little steep and nerving...a 4x4 and/or high clearance vehicle is a plus. You will find the trail beginning when you get down to the river; roadside parking is limited. There are a couple of porta-potties there if needed. The trail itself is pretty easy and straight forward; not a lot of elevation changes. Some spots are narrow, so passing people going the oppisite direction (especially when you each have dogs), needs to be taken slowly. You end up at the waterfall, which is nice, but lacking in room when many people are there at the same time. BRING TECNU OR HAVE IT HANDY AFTER HIKE...POISEN OAK GALORE!
