Skiers who want a bargain this season will have to give up part of their Labor Day weekend to get the best deals on lift tickets, but even early birds will pay significantly more than last year.

As in past years, several rival resorts will converge on Front Range gear stores from Aug. 31 to Sept. 3 to peddle discount passes to those ready to commit to hitting the slopes with some regularity this winter.

"That's sort of the first fork in the road - are you going to commit to a season pass this year or not?" said Chris Jarnot, head of marketing at Vail Resorts Inc. "If you are, then it really pays to pay close attention early in the season, when we're making the best prices available."

Many resorts will continue to ratchet up prices, but plenty of people will likely take the bait because it will only cost more as the season draws closer - and still more at the ticket counter once the season starts.

In Colorado, Jarnot estimates the company sells almost half its passes, including those sold during a spring promotion, by the end of this weekend.

The Broomfield-based operator owns four ski areas in the state: Breckenridge, Vail, Beaver Creek and Keystone.

All its passes will cost more starting Tuesday, but it won't decide exactly how much to hike prices until then.

The company keeps a close watch on rival areas and announced a four-pack deal for Keystone and Arapahoe Basin late Tuesday that matches the recently announced $129 price for a pass good for four days at Winter Park.

Even at that price, Winter Park's pass jumped 30 percent from last year. Intrawest is offering a four-day pass at Copper Mountain for $119, a 40 percent increase from last year's $84 deal.

Deals from several resorts

The blitz begins this weekend as ski areas begin touting limited-time offers for an array of passes. Even with price hikes this year, those who act early will pay far less than procrastinators. Here's a sampling of deals for various resorts:

• Vail's Colorado Pass, which allows unlimited visits to Keystone, Breckenridge and Arapahoe Basin, as well as 10 days at Vail and Beaver Creek, goes for $419 through the weekend. That's up 11 percent from last year. The company's passes go on sale this weekend at Ski Rex at Colorado Ski & Golf in Aurora and Sniagrab at the Sports Authority in Denver.

• A four-day pass to Winter Park will go for $129 this season, up 30 percent, while Copper's four-day pass will cost $119, up 40 percent. Those prices are good until Oct. 15. The higher prices entitle holders to discount lift tickets for friends and family.
