This hiking and waterfall tour literally was the climax of our trip to Asheville, NC. Keith owns the company and gives the tour personally. He is the most knowledgeable person I have ever met that I've toured with (and my wife and I have toured a lot). Most of the 5-6 hour tour was spent learning about the history of the area and the environment, horticulture, insects, mushrooms, foliage, waterfalls, etc... There was not a single question we asked Keith that he could not answer with details you would normally need to use Google or a library for. He is a walking encyclopedia of information, is entertaining, and made a 5.5 hour tour go by quickly. The tour went by quickly thanks to Keith and we learned a lot and highly recommend you make this tour a part of your Asheville experience!
