As someone who has never "rock crawled" driving a Jeep or UTV, there were at least four times on this trip that I thought to myself, "I can't believe they just let us do this!"
On the other hand, I had great instructions before we set out, and our guide, Charlie, made sure we understood each obstacle and what we would be doing on each one. On the most difficult obstacles, he stood ahead of us and guided is through with hand signals.
I took the sunset tour, and it was a beautiful, chilly evening.
I highly recommend. It will be something you'll remember for a lifetime.
