My 11 year old son and I loved our hike in the Buckskin Gulch with Yermo. We're avid outdoor folks with a lot of hiking experience and I initially wondered whether I really needed to hire a guide....I'm SO glad I did! First, there's no established trail to take you to the middle entrance point of the gulch (the most beautiful area)...but Yermo knows this area like the back of his hand and took us straight to it. Then to actually get into the gulch takes some semi-technical rock scrambling maneuvers with some significant exposure. I'm somewhat fearful of heights, but Yermo's expertise and clear communication made me feel very safe. He literally knows each and every foot and handhold on the rock face and with his guidance we both made it down pretty easily. And then the gulch itself!.....It is absolutely stunning! Picture can't do it justice. I felt like I had entered a special sacred world down there. It's really and experience like no other. As I said, we hike a lot, and this experience is absolutely one of my favorites and one I will never forget. Yermo knows endless information about the geology, flora, and fauna, and pointed out many interesting things we would have completely missed had we been on our own, including some beautiful rock art. I highly recommend this tour, and Yermo.
