The lifts opened at 8:30 a.m., but snow lovers were waiting in line several hours beforehand.
Chair 9 opened from top to bottom, serving Upper Park Run, Expressway, Gulch and Lower Park Run trails.
The Big Bear area got a good dusting of snow from last week's storm, but not too much. That's when the resort put its snow-making machines to work.
The entire resort isn't open - only a limited number of runs are available. Also, no beginner grails are open.
Chris Riddle, the vice president of marketing at Bear Mountain Resorts, said it's not only about the runs - it's also about the tricks.
"Jumps, rails, boxes, and we've got several jumps and a bunch of rails and boxes. So not only is it just opening day, it's opening day with some fun here," said Riddle.
Due to limited available runs, lift tickets will be offered at an early-season rate of $40 for adults 22 and older; $35 for young adults ages 13-21; and $16 for children ages 7-12. Season Passes, individual tickets and group tickets are on sale now. For more information or to purchase passes, call 909.866.5766 or visit BigBearMountainResorts.com. For the 24-hour snow report, call 800-Bear-Mtn.
Opening day celebrations will include music, giveaways and drink specials.
Snow Summit does not yet have a scheduled day to open.
