AVOID!! AVOID!! AVOID!! Bought Groupon for 2 hr ride. Made 9-11a reservation online, had out of town guest with us, drove 1 hr to get there. Arrived 20 minutes early and were told no wrangler to take us - the group in front of us was bigger than their reservation. So they took all of them! We were told we could wait and go at 11a after they returned! ARE YOU KIDDING. What is the point of a RESERVATION! They clearly decided accepting extras in the other group was better than honoring our reservation. We couldn't stay - they didn't even apologize...whoever was in charge there could not have cared less about customer service.
Add to this that the horses there live in squalor, up to their fetlock (about a foot up on legs) in manure and the corrals 1' deep manure...so if you have any sympathy for animals, you may not feel too good.
There are plenty of other options in the Valley - having grown up on a ranch - I strongly encourage all (novices and experts) to look somewhere else. My guess, after our experience, is that they are doing Groupon not to attract new business but because they are having trouble getting any business.
We have reported our unfortunate incident to Groupon and are getting a refund. Wish I could leave 0 Stars.
