Bird and Hike has a succinct webpage:
This easy, 1.5-mile loop trail starts at the Visitor Center, wanders east and south down a sandy wash, heads west around the south side of the Hole-in-the-Wall hills, climbs up through the Hole-in-the-Wall cleft on the Rings Trail, and then follows the road for 0.2 miles back …
Almost every tourists stops at Hole-in-the-Wall. But not all are willing to try the assisted scramble.
I’d call it a perfect little day hike for a confident walker. The scenery is desert classic.
Add on the “Nature Trail” to the campground. Desert vegetation is signed, … all the bushes looking somewhat similar. With unlikely names like: Paper Bag Bush, Hedgehog Cactus, Horsebrush, etc.
Tent caterpillars were everywhere when I was there.
… Mojave National Preserve, at 1.6 million acres, is the third largest National Park Service managed area in the Lower 48; only Death Valley and Yellowstone are larger. …
It’s so close to Vegas, I’m surprised more tourists don’t visit. There’s no Park entrance fee. And “wild camping” is allowed almost everywhere.
