We took one day to drive up the road to Mt. Lemon. We went as far as you can drive (about 27 miles) and enjoyed it alot. The road leaves just NE of Tucson and goes from about 2500 ft elevation up to over 8000 ft. The views out and down to Tucson and all around are fantastic! Not many tourists the day we went because it's winter (Feb 5). But come summer this is an extremely popular place to go and cool down form the deseert heat. And they even have a small ski lift at the end of the road.
