WINTER PARK, Colo. — Winter Park Resort will open Saturday, 11 days earlier than previously planned and the earliest first day in its 80-year history.

With more than 40 inches of natural snow falling this month and amplified snowmaking systems, the resort was able to push up its opener from Nov. 13.

Snowmaking only began last week, but this week’s strong storms helped make for an early opening.

The first chair is scheduled for 8:30 a.m. Saturday at the Arrow Lift.

“Mother Nature brought the snow to Winter Park especially early this year, so we are taking advantage of the conditions and are excited to open the mountain more than a week earlier than expected,” marketing director Liz Agostin said.

On Nov. 16, Winter Park will mark eight decades as the state’s oldest continuously operated resort by offering $40 lift tickets (minimum two tickets) that will be good only for that day.

Winter Park will become the fourth resort to open earlier than planned this weekend, bringing the number of openings in the state to seven.
