This is probably the best area to see scenic views and certainly to see wildlife. Every time I have driven this road I have seen animals. Very highly recommended.
The town of Jasper is pretty cool. Its not overrun completely by large chains. You can also see elk just walking around the town. The candy store in town is awesome to.
This was a cool place. I think its about 45min from Los Vegas. You can see mountain sheep, really cool coloured rock formations and a nice drive. For the price its certainly worth it. I believe you can camp in the park as well. Not sure about hookups... but would be a nice place to stay.
