I spent a night in Shinleaf walk in campground in April as part of a backpacking trip along the Falls Lake MST trail, sections 8-12. The fact that it doesn't have vehicle access to the sites makes it somewhat not popular with the usual camping crowd. It's a pretty big campground, but when I was there it was mostly empty. My site had the lake view and I spent the evening watching the sunset on the lake, it was amazing.

The bathroom was clean. I didn't use the shower, but I think it was available.

It's a great spot if you backpack MST or otherwise don't mind taking your stuff from the car to the site on foot.

I booked site 39 and it was great, I also remember that the two adjacent sites 37 and 38 were connected and could serve as a great spot for a small group.
