Being a local, I have done this drive on my own probably a hundred times or more. I took the tour last summer so I would be able to let the guests at my hotel know what it was all about. This tour does not disappoint! I had SO MUCH FUN! Even though I knew most of the history, geology, and biology of the area, I still learned a lot from our amazing tour guide. She was very entertaining as well. With the snacks and lunch provided in the price, this tour is a steal of a deal. I would highly recommend this to all age groups, as there is something interesting for everyone!
