Texas Springs campsite is off Hwy 190 in Death Valley State Park, near Furnace Creek. It has 92 tent and RV sites and costs $12 a night.
We went in late February, a popular time to go because it's not as hot as summer time -- high 80s and 90s vs. 100s, but surprisingly the campground had several sites to choose from that year. The campgrounds have very few shade areas, but we found a site with a small tree/large bush. It was enough shade for a couple of people to sit under, which we took advantage of when first arriving, as we weren't acclimated to the heat. The ground was hard, making it a little difficult to stake our tents, but after some pounding the stakes went in securely.
The sites were large enough. Our group of 7 found spots for three tents, one being a gigantic three-room tent. Be wary of the more low-lying flat spots, though. While they might seem ideal, we heard from a group who has made the trek that very weekend for the last 15 years that it often rains during late Feb./early March and after trial and error, they finally found a campsite that doesn't flood. Thankfully it was dry the one night we were there. It was windy, however, and that three-room tent flapped incessantly all night.
With flush toilets, running water, a fire pit, and picnic benches available, this campsite was pure camping luxurious.
