I had a wonderful time on this tour. It was not at all crowded, with just 3 women and the guide. He was knowledgable, humorous, enthusiastic, conscientious and unaffected.We went up a very rocky road, but he knew how to drive it so I did not get jostled much at all. It was the right amount of adventure and hiking. The views were astounding and could not be reached by car, no way. I recommend this tour, whether you believe in the Vortexes or not. Super informative!
