What a gem to have such a large museum in Sin City. At $8 per adult and $4 per kid it is very fairly priced when compared to other Natural History museums around the country. Very easy to google a buy one get one free coupon though, so try that before visiting!
Located next to a park, across from Childrens museum and adjacent to the Old Morman Fort this is totally an area to hang out at ALL day.
The variety of exhibits at this museum is great, a little bit of everything. Yes some of the exhibits are old, some are kind of cheesy, but it just shows you that Vegas isn't putting their money where it needs to be.
Take your kids and view this museum through their eyes and you will have a blast!
