Mt. Wasson is the highest peak (4,687') in the Tucson Mountains west of the city. Take El Camino del Cerro (exit 252 from I-10) west about 5 miles from the freeway to the trailhead.
From the top you will have an expansive east view of the city and Catalina Mountains. To the west, a grand view of the Avra Valley.
Once you get to the top, you can turn around, but rather than coming all the way back to where you parked your car, you can pick up the trail north along the ridge to Picture Rocks. The trail ends at Picture Rocks Road. You might want to pre-arrange for a friend to pick you up in a car here and take you and your hiking companions back to the city.
Alternatively, from the top of Wasson Peak, you can continue on the trail that heads down the west side of the
mountain to the Desert Museum. This is the King Canyon Trail.
Here too, you can have a friend with a car meet you. If you take this route, you all might have a meal at the Desert Museum.
