My boyfriend and I booked this Oasis Tour upon our arrival in Tucson. We tend to have active/adventurous vacations and normally I would not have booked such a tour, but it turned out to be AWESOME! Timothy is extremely knowledgeable about Mt. Lemmon and the Tucson area and we had a fantastic day with him. The ride was very scenic and we stopped for a number of great photo opportunities - Timothy knew all the best places. I highly recommend this tour and guide. As someone else mentioned - do not let the "audio tour" part turn you off - it is only part of the tour and actually quite interesting!
