We had a great time touring the area and hiking in to see some of the area waterfalls. Keith has great knowledge of the area, the scenic spots, the flora and fauna, and even the Biltmore!
The hiking is not particularly difficult, more "walk-in-the-woods" on wide trails, and the scenery is beautiful. Keith seems to be able to adjust the tour depending on the clients interests and abilities, as well as local conditions (weather, crowds, time-of-season, etc.).
I highly recommend this tour to see the local natural area with an expert guide.
