Mt Baldy Ski Lifts, or "Baldy" for short, is a family owned and operated ski resort located in San Bernardino County, California, on Mount San Antonio (AKA Mt Baldy). The resort is run by the Ellingson family. The ski resort features traditional runs, open bowls, chutes, and tree runs; and claims to be "The largest and steepest resort in Southern California," with 26 runs spanning 3 mountains featuring a peak elevation of 8,600 ft (2,600 m). Baldy spans 800 acres (320 ha) with a 2,100 ft (640 m) vertical drop, and is located just 45 mi (72 km) from Los Angeles, making it the closest resort to the city.
The vintage ski lifts were installed half a century ago by Harwood Developments. They were operated as Mt Baldy Ski Lifts Inc, and managed by Herbert Leffler from 1953 until his retirement in 1969. An investment group under the leadership of Charles Lewsader purchased the resort in 1969.
