A little bit outside of Las Vegas, there is a great art installation.
Seven colorful rock formations seemingly coming out of the desert is amazing. The colors are bright - almost highlighter like.
I came out with a few friends - even an uber ride was only $30ish or so. We asked the driver to stay out there to help us get back so that might be the best way if you don't have a car in Vegas.
Come with a group of friends and decide to take a ton of photoshoot like pictures.
Protip: go and hang out during a trip to Vegas.
