Hike d this trail on Memorial Day weekend. Apparently no one had used this trail in some time as the weeds had grown up over the trail in a few spots. Overall, I enjoyed the hike.
Note that there is no trail head sign. Look for the traffic control barrier just off of the paved road leading from the Lake to the campground.
