Mammoth Mountain's 2026/27 season runs roughly from November 13, 2026 to May 25, 2027 — about 193 days of skiing. The opening, November 13, 2026, has been announced by the resort: it is published by mammothmountain.com. The May 25, 2027 closing is our own calculation: it is usually announced only weeks ahead. The up-to-date version, with its source, is on the opening-dates page.
Expected opening: November 13, 2026. Expected closing: May 25, 2027. Opening depends on enough snow at the 2424 m base, so it can move a week or two either way; with a 3369 m top station, the upper mountain usually holds out longer than the base at the end of the season. Closing tends to be pushed to Easter when it falls late.
Like most alpine resorts, Mammoth Mountain's lifts typically run roughly from 9:00 to 16:30–17:00, with the occasional night session on special dates. The exact daily schedule is published on the resort's official site.
The two weeks around opening day, plus Christmas and Easter holidays, are when sizes and the better models sell out first in Mammoth Mountain. Booking with the opening date already on the calendar — November 13, 2026 this season — is the simple way to avoid being left with what's spare.
