The Summit at Snoqualmie is offering its four Big S season passes again. The four-season passes accommodate the needs of different ski and snowboard schedules. Those who miss the first sale will have a chance at the second sale.

The Big S Unlimited, which allows access anytime to all Summit ski hills and Alpental, is on sale with the lowest rates through Sept. 15. Adults can purchase the pass for $359. Teen ages 13-18 and college students can purchase the pass for $289. Passes for seniors and youths ages 7-12 cost $229.

The Big S Unlimited Gold pass is for those who want to ski anytime at the Summit or Alpental, plus want the option to visit other ski areas. The pass includes five days free at Crystal Mountain and 10 days free or at 50 percent off at other Boyne ski resorts. Some blackout dates apply at Crystal and the other Boyne resorts.

The Big S L-T-D season pass, which runs $30-60 less than the Big S Unlimited passes, offers skiing or snowboarding anytime, but with restrictions on locations. The pass is valid at Summits West, Central, and East anytime, but only midweek at Alpental. Passholders may purchase Saturday or Sunday lift tickets at Alpental for $10 off.

The Big S Night Pass is valid for night skiing from 4-10 p.m. at all three Summit areas and Alpental. The pass costs $209.

All four passes are available at their lowest prices through Sept. 15. The four passes will still be available for purchase, but rates from Sept. 16 through Oct. 31 have not been announced yet. The Big S Unlimited Gold pass is only available until Oct. 31.
