Beautiful! Slightly Trafficked...
We drove up this road early on the Saturday of Labor Day weekend and of the first 8 designated spots only about 3 were full. We took the last one (just after 2ish miles from the entrance at the road) and it was absolutely gorgeous. Our little site sat on small ridge with a somewhat steep but short trail down to the creek. No picnic tables, but there was a really cute fire ring. The trails up the road are popular, and over the course of the weekend there were pretty frequent cars and even a few folks walking. We didn't mind too much, but the site is right off the road so you're not secluded or especially private. The trade off feels worth it for the beautiful site and proximity to the creek.
