It is a family-oriented mountain, with a wider range of beginner and intermediate slopes than other nearby ski resorts; 50% of its slopes are graded "beginner" or "intermediate," the highest such ratio in the Salt Lake City area.  Solitude was one of the first major US resorts to adopt an RFID lift ticket system, allowing lift lines to move more efficiently while reducing "lift poaching".  It was followed by Alta Ski Area in 2007.  Solitude is adjacent to Brighton Ski Resort near the top of Big Cottonwood Canyon.  Solitude and Brighton offer a common "Solbright Pass" which provides access to both resorts for a nominal surcharge.
