Logandale OHV It's a section of Red Rock where you can off road and have fun.
These guys are right outside the entrance road in Moapa.

Not far out of town at the Desert National Wildlife Preserve there are some easy trips.
If you got insurance on the rental car, Mormon Well road is nice or Alamo Rd heading North is mostly smooth graded gravel up to sheep pass before it gets slightly rougher. There are some interesting old paths and signs to the east off Alamo.
