Sentinel Peak, also known as "A" Mountain, is local landmark, as well as a city park. Fans of the University of Arizona maintain the decades-long tradition of painting a giant "A" on the side of the mountain in honor of their alma mater. Sentinel Peak is often referred to as Tucson's birthplace, because it is the former site of an ancestral Pima Village. Although this is a non-traditional park, it's certainly worth the hike up simply for the dazzling views of the Tucson valley. Plus, the park recently received several upgrades, including two shaded plazas, new park entry signs, handicapped-accessible parking spaces and a new paved path.
