We backpacked to Rancheria camp and stayed for 2 nights. It's about 6 miles from the trailhead, and an incredibly gorgeous hike. It was pretty hot when we went, and a little hazy from wildfires, but still totally worth it.
The camping area itself is pretty big. There were a few other groups camping while we were there, but we hardly knew they were there. The river access was close by, so we could filter water.
We took a day hike to Tiltill valley, and it was so beautiful there. Highly recommended.
There were a lot of bugs, so for the first time ever I used my bug net and was very thankful I had it on this trip.
