My husband and I stayed here for 2 nights in April 2013. The campsite is on the valley floor and the surrounding rock formations are GORGEOUS, particularly at sunset while we were making dinner. There is no firewood around so you have to bring your own. The bathrooms were nice and there were large outdoor sinks to wash your dishes in. The ground was rock hard and it was somewhat difficult hammering the tent poles into the earth but we managed. The ground was ROCK HARD so if you're in a tent with a sleeping bag I'd recommend an inflatable mattress or sleeping bag mat. We saw a rabbit one morning which was cool.
The worst part about this campground was that if you have a need for a ranger off-season you're out of luck. There was NO ranger presence in April when we were there. Unfortunately, we had some very loud neighbors at the next campsite on the first night who also left out trash overnight which attracted crows. This was concerning since we could hear coyotes at night! I went to the visitor's center to ask which ranger I could contact and they referred me to the San Bernardino police department (which is like 2 hours away!). I was shocked that they couldn't even refer us to any on-duty rangers to help out.
There were showers nearby at Furnace Creek. We went to the front desk and got a $5 pass each which gave us 24 hours of access to the resort's pool and showers. Furnace Creek village also had nice amenities (restaurants, gift shop, market) which were useful.
Other than the ranger issue, this was a beautiful campground which I recommend.
