Sentinel Peak Hike Description
The Sentinel Peak hike is a very popular easy trail in Tucson. This route climbs around the top of Sentinel Peak, also known as “A” Mountain for the University of Arizona logo on its slopes. The logo was created by students in 1916, and each year’s homecoming is started with a lighting of the A.
Before it was claimed by the university, Sentinel Peak was used for signal fires by Native American inhabitants. Crops were grown along its base and it was later used in the Civil War.
Sentinel Peak is a 2897ft mountain made of up of layers of igneous rock from volcanic activity in years past. The mountain is a small part of the rich archeological history of the Santa Cruz Valley, which dates back over 4,000 years.
The hike up Sentinel Peak is quick and easy. With gentle elevation gain and a paved path, we recommend it for all ages and skill levels. The views of Tucson and the surrounding mountains are great, spanning in all directions.
This route has no shade and the temperatures in Tucson can soar. You’ll want to make sure you get out early enough to finish before the heat of the day sets in. Bring water and wear sunscreen.
While dogs are allowed on this trail on leash, we recommend either leaving them at home or putting boots on them due to the broken glass commonly found on this trail. Unfortunately, the mountain occasionally attracts partiers who don’t clean up after themselves. Watch your step.
From the trailhead, head up S Sentinel Peak Road to where it splits. Stay right to wrap around the southern face of the mountain, which has a view of the Santa Cruz River and South Tucson.
Round the peak, stopping at the viewpoint that looks out over the city and the Pusch Ridge Wilderness. Continue around the north end of the peak, looking over at Tumamoc Hill on your return route. Where the trail reconnects, retrace your route back to the parking lot.

Tucson
On Sentinel Peak, your view of Tucson is unimpeded and wide. Home to the University of Arizona, Tucson is the second-largest city in Arizona after Phoenix. Tucson was founded as a military fort by the Spanish in 1775, became part of Mexican Sonora in 1821, and then was acquired by the United States in 1853. The name Tucson comes from the Spanish Tucsón, which means “at the base of the black hill.” This is in reference to the basalt-covered Sentinel Peak. Tucson is surrounded by five mountain ranges.
