If you're debating whether or not to book this experience, do it. We did the 7 a.m. hike with the 6 a.m. pick up, and even coming off of only a few hours of sleep, it was probably the best experience we had in Vegas. The Valley of Fire itself is gorgeous, and our guide Matt made the experience truly incredible. He was SO knowledgeable, made sure to make the hike interesting while steering clear of crowds, and went above and beyond taking care to get lots of great pictures from all angles of my partner and I. He is a very kind person, and made the group feel comfortable and empowered to do some of the trickier bits of climbing. If I could do this trip again, I would in a heartbeat, and there's plenty of space to explore, so maybe I will someday.
