This lovely trail offers varied terrain and views of oaks and the Tucson Basin as it drops in to Sabino Canyon. There are some rocky areas in this trail that require good footing and some very light scrambling.
The trailhead for Sunset Trail sits right off the Santa Catalina Highway, across from the Butterfly Trailhead. The parking is free here and the first mile or so of trail runs through a road with some cabins, but there is signage indicating where the trail is, so it's easy to stay on course.
Eventually the trail hits a creek crossing at the bottom of the canyon and merges with Marshall Gulch Trailhead, where you can continue for a longer hike, or turn around.
