Had a great experience with Corral West. We bought groupons for our visit. There were four of us and we all had an enjoyable time. Our guide was very friendly and informative about the horses and the land that we were on. The trail was absolutely gorgeous, and fairly quiet. The horses were all well behaved - just a bit distracted on the trail when hungry.
The check in process was very simple. They provided a clean bathroom. It did kind of suck that we had to pay parking for the regional park, but it was a small matter. I see it as a donation to our parks. Would definitely recommended this establishment!
Oh and they had cowboys hats and boots available for borrowing if wanted or needed.
