Skiers and snowboarders, it’s time to hit the slopes. All three Mountain High resorts are open, East, West, and North. When Mountain High is fully open we offer more trails than Snow Summit, more acres than Bear Mountain, and more terrain features than Snow Valley and you can do it for less at Mountain High. We have more than 200 professional instructors and we want to teach you. Mountain High is Southern California’s closest winter resort, just 20 minutes off I-15 with no mountain. Mountain High is where Southern California learns to ski and snowboard. Visit mthigh.com for money saving lesson packages for ages 4 and up.
