This place is a must see if you want something to do in Vegas that does not involve casinos or hookers.
After taking the Charleston exit off of the 215 freeway, keep going until you see the sign for Calico, make a right turn and park in the parking lot. It's actually super easy to find, and parking and entrance are both free. Red Rock Canyon will cost you. The parking area has 2 outhouses with toilet paper but no flush, so plan accordingly. There are many trails to choose from and all of them have beautiful scenery. Lots of family with children, so there are plenty of easy routes for everyone.
I hiked upwards, and went for some of the steeper trails. Once I got to a high point, the view was incredible. You can see the whole valley and all the different rock formations and color layers in the mountains.
Highly recommend!
