YEP- if your reason to go there is to have a photo in front of the sign- it's a LONG day?? It's a boring ride in my opinion, trees and more trees, oh yes- plenty of pipeline. Frankly- I would never do this via bus in both directions and never in one day. A superior tour is the fly/shuttle round trip.. At least you get a look from 2 different perspectives. The www.toursaver.com
has a 2 for one coupon, so this option is far better in my opinion.
