Came here from SF Bay for 2 nights on a weekend.  Obtained permit from the ranger station and had to pick a district I would camp in the first night (to limit amount of campers in a region per night).  Hiked about 8 miles southwest to a lake the first night and camped in my hammock by the lake.  Second day backpacked about 12 miles northeast to another lake and was able to grab a spot to set up my hammock next to some picnic tables and a restroom.  Saw plenty of wildlife (lizards, snakes, birds, fish).  It was fairly hot in mid-spring, and there is not much shade on the trails, especially the dirt roads.
