Trail Route Description
Passage 10 traverses through the transition zone between the Rincon and Santa Catalina Mountains. This section begins in low rolling grasslands with sweeping views of the rounded Rincons to the south. It features golden grasses, rocky hillsides and granite boulders. In the springtime, wildflowers add color to the landscape, especially the tall, purple flower heads of thistle that adorn the trail.
The trail crosses Caliente Creek with shady, large cottonwood trees and a seasonal flow of water.
Scenic singletrack ascends a steep set of switchbacks to a saddle above Molino Basin with panoramic views. To the east is the San Pedro River Valley and the Rincon Mountains, to the west is Sabino Canyon, and to the north-northwest, Mount Lemmon’s sheer granite cliffs reveal the rocky terrain waiting ahead.
There are two campgrounds near the terminus of this section. Molino Basin Campground closes for the summer (usually at the end of April), and the water is shut off at that time. Gordon Hirabayashi Campground is open year-round but has no water.
