Beautiful, short drive. Amazing desert views. Lots of hiking trails. Interactive visitors center. Close enough to be worth it, far enough you can shake off the Strip stank and have some fun.
Gets hella packed on the weekends, try mid week.
Avoid during summer unless you go super duper early & avoid the high heat.
Theres a huge picnic & restroom area outside the park, off the road, between the entrance & exit to it that still gives good views.
