We’ve camped in Death Valley about a dozen times.  We alternate between Furnace Creek Campground and Texas Springs Campground.  Furnace Creek is adjacent to the Visitor Center and the Furnace Creek Inn.  It’s within walking distance of both places.  The Texas Spring Campground is on a hill above Furnace Creek.  It takes about 10-15 minutes to bike ride to Furnace Creek or 30 minutes to walk.  Texas Spring has great views (although it can get windy) but has more of a camping experience.  Furnace Creek is mainly just parking spots.  Both campgrounds have flush toilets.  This is a great location to explore the park.  Zebrinski Point, Slot Canyon, Fish Creek, Sand Dunes are all fun places to hike and explore. Tip:  Pay the $10 a day for the pool pass at Furnace Creek Inn.  Not only does it give you access to hot showers but also use of the spring fed pool.  The pool stays open til really late (11 pm?) and it is so fun to swim at night when the temperature is still in the 80’s - (May camping).
