Sweetwater Trail

One of the four mountain ranges that cradle the Tucson valley, the Tucson Mountains are home to Saguaro National Park West and the world renowned Arizona-Sonora Desert Museum. The range is a showpiece for the Sonoran Desert and its exotic ecosystem of desert-adapted plants and animals.

The Tucson Mountains are relatively low elevation and therefore blistering hot in the summer as well as in early fall and late spring, so winter is the best time to take advantage of the Park’s trail network and enjoy the unique scenery and landscapes. The range is a very popular hiking destination during winter months, attracting out of town visitors as well as locals.

Located on the east side of the range, the Sweetwater Trail is very easy to access from the Tucson metro area. The trail ends after 3.2 miles, when it joins the King Canyon Trail at a high saddle on the crest of the range. From the saddle many hikers choose to walk the additional 1.2 miles up the King Canyon Trail to the high point of the Tucson Mountains — Wasson Peak. The 360 degree panorama at the top of Wasson makes the extra effort well worthwhile.

The Sweetwater Trail presents a great display of Saguaro cactus, the Sonoran Desert’s signature plant species. You’ll also see many specimens of Ironwood trees and Jojoba plants. Easy to access, wonderful views, and a fine experience of the ecology of the Sonoran desert — sorry for taking advantage of too-obvious play on words, but this is a sweet hike!

Find the trailhead by exiting I-10 at the Ruthrauff exit. West of I-10, Ruthrauff becomes El Camino Del Cerro which is simply followed west to the end of the road, and trailhead parking. A hundred yards or so up the trail a junction is reached – the left (south) fork is the Sweetwater Trail. The trail weaves its way south for a while, up and down across a few drainages, before finally swinging west and settling into a steady uphill climb to a prominent saddle and the junction with the King Canyon Trail.

Season: Fall, winter and spring. The Tucson Mountains are low elevation and very, very hot during summer months, late spring and in early fall. This hike is most enjoyable on cool winter days.

Water: None: bring plenty of your own.

Note: Dogs and pets are not permitted on this trail. Though fees are not collected at the trailhead, Saguaro National Park is a fee area.

Difficulty: The trip to trail’s end at the saddle is 3.2 miles one way with a 1,100 elevation gain. Those who continue to Wasson Peak will walk 4.4 miles one way and take on 1,900 feet in elevation gain. Moderately difficult.
