Stayed for 14 days. The weekends were fuller but still pretty quiet. During the week there were just enough people for it not to feel creepily lonely. The lake was beautiful and we hiked a few of the trails that go near/around it. I liked that it was a no-wake lake. It didn't have that crazy motor boat and jet skis everywhere feel.
The campsite itself was at the bottom of two hills and much damper than the surrounding areas. That meant lots of mosquitos! No grass on this site, but the ones with higher numbers have lots of grass and running around room for kids.
So nice, though I wish we could have stayed longer!
