White sands national monument is absolutely stunning. The campground is on a loop you have to follow signs up and down dunes until you reach your assigned site. Super cheap, super private, super beautiful! Backcountry camping makes its sound more intimidating than it is. Pack light because you do have to walk all your stuff in, but it’s not far and it’s not a challenging hike. Amazing sunrise and sunset. You don’t have to wear shoes here! Very child friendly. I don’t have kids but it seems very conducive for kid camping. It is open and spacious and you wouldn’t disturb anyone.
