Sutherland Loop

Sutherland Loop is a 30.2 mile route through the Pusch Ridge Wilderness and across the Santa Catalina Mountains. This loop route showcases the stunning diversity of Southern Arizona's landscapes, from the rugged Sutherland Trailhead to the serene heights of Mount Lemmon and back. It is an epic journey for seasoned hikers and backpackers seeking a challenging adventure with rewarding vistas, ecological diversity, and a sense of wilderness exploration.  

The route begins at the Sutherland Trailhead, located east of Oro Valley and northeast of Tucson, Arizona, and unfurls eastward to Romero Pass. As it ascends through deep canyons and verdant forests, hikers are treated to a rich tapestry of biodiversity. Along the way, you'll discover spectacular swimming holes, towering saguaros, and sections of steep, strenuous terrain.

Hikers will start with a gradual ascent via Sutherland Trail #6, which becomes more demanding as you near the Mount Lemmon Trail. The climb to Mount Lemmon Peak, standing tall at 9,159 feet as the highest point in the Santa Catalina Mountains, presents a formidable challenge but offers rewarding panoramic views of the enveloping desert and forest landscapes. At the summit, pause to appreciate the expansive vistas and your accomplishment.

From the peak, you'll descend via Aspen Trail #93. This section leads to Marshall Gulch Trail #3, featuring lush woodlands and creek-side trails.

Then, you'll return to Aspen Trail #93 and connect to Wilderness of Rocks Trail #44, revealing an enchanting landscape of rock formations and pine forests—a stark contrast to the desert terrain below.

The route proceeds along Mount Lemmon Trail #5 to Romero Pass, where you'll join the Romero Pass Trail. This portion navigates through varied terrain, incorporating steep descents, lush valleys, and occasional water crossings.

You'll continue on Romero Trail #8 and Romero Canyon Trail, leading back to the Sutherland Trailhead to conclude your journey.
