I was able to walk up and get a spot in mid-March. There are two areas- one by the lake, which has good enough cell service and is for tents, and another by the beach which has no cell service at all but full hookups. I stayed in the lake area and was the only person there that night.

The bathrooms in the lake area are okay- flush toilets and a free hot a shower. The shower is a push button though, which I found annoying since that made the temperature fluctuate a lot. By the beach area the bathrooms seemed much nicer.

The sites are beautiful and grassy, right on the lake. Basically no privacy between sites though. There are tons of great hikes in the area and the beaches are gorgeous and huge. I loved my stay here and would gladly come back.
