River was the most excellent guide you could ask for. I booked this adventure for my friends for our vacation to Utah. I am so glad I did. We had an absolute blast. We decided to all use the same 4X4 (there were four of us) but when we got there, they continued to offer an extra 4X4 if we wanted. They went above and beyond with hospitality. The tour itself was amazing. We got to see so much in the time we were gone. As my first line I wrote, our guide was River. I don't know if you can request who takes you on the tour, but if you can, you will not regret picking him. He was an excellent guide, full of knowledge about the sites we visited, hilariously funny, and an amazing photographer. If we ever come back, we would book again. 10/10.
