A spectacular desert canyon cut into the south side of the Santa Catalina Mountains, this area is justifiably popular with both locals and visitors and is the starting point for a number of hiking trails. Half-hourly trams operated by Sabino Canyon Tours ($8/$4 adults/children) can take visitors nine stops up into the canyon; a separate tram ($3/$1 adults/children) will take you into Bear Canyon and to the trailhead of the popular Seven Falls Trail. Free trail maps are available at the visitor center, which also sells a good selection of regional hiking guidebooks and topo maps.
