This trail starts as a city street but turns into a dirt road that drops deep into the Tanque Verde Canyon. On this trail you will encounter some of the most extreme off-roading in the state of Arizona. This tour is not for the faint of heart as your Hummer will be tested to the max of it’s capabilities. This tour also has great views of Tucson and showcases many different types of southern Arizona’s cactus. The off-road terrain on this adventure is very difficult. Allow 4-5 hours for this tour.
