We had a fabulous time on the half day Emerald Cave tour. The pickup was convenient from a popular Las Vegas hotel. The drive was only 1 hour, so very reasonable. The kayaking was a lot of fun, not too strenuous but still a 3 hour workout. The green water in the cave was a highlight, as we took some great photos. Our tour guide Preston was really great. He gave us some history, which was the right amount but not so much that it bored us. He encouraged all of us in the group to get acquainted, and so we did! Preston was very easy to talk to and he made us all comfortable. All in all a really fun time that I would highly recommend, especially with Preston.
