End of the trip and we were tired. A nice side trip without going off from Highway 95. Parking is $7. Then you go down the escalator and see the prices. $11 for the visitor center, $30 for tour, $40 for tour with plant tour. Yeah, we decided to just walk above and take pictures. Gift shop is nice and affordable. I got a nice wool woven Indian mat to put my souvenirs for only $7. The other stores along the street were charging more like $10-15.
