Mountain High East, beloved by thrill-seekers, opened in 1948 under the name of “Holiday Hill.” In 1979, Holiday Hill was sold to the current owner of Mountain High. At first, the newly-purchased Holiday Hill was used as parking for Mountain High, and when snow levels permitted it was also used as added terrain. The longest ski run in Southern California is known as Goldrush, and can be found at Mountain High's East Resort.
What is presently known as Mountain High North was identified as the Table Mountain Ski Area in 1938. In 1975, the name was changed to “Ski Sunrise.” In 2004, Ski Sunrise was sold to the owners of Mountain High and is now used as a tubing park. For those who are new to winter adventuring, Mountain High North also provides beginning-level terrain and other snow-playing activities.
