At this point, we had finished the John Muir Trail and just needed a cheap place to stay. Diaz lake fit the ticket - had outdoor showers and everything. Was really loud at night, lots of drunk folks. People seemed to use this place for power boating and partying, which isn't really my cup of tea. Otherwise, the amenities were nice, and there were plenty of nice camp sites to choose from. Layout was a little confusing, so grab a map ;)
