Both the East (Rincon Mountain District) and West (Tucson Mountain District) sides of Saguaro National Park offer unique experiences and beautiful scenery. The East side is known for its stunning sunrises, longer scenic loop drive (Cactus Forest Loop), and more extensive trail system. The West side is famous for its dense saguaro forests, beautiful sunsets, and the shorter scenic loop drive (Bajada Loop). Your choice depends on your personal preferences and interests.
