The Sunday River Mega Pass celebrates 50 years of growth at the Maine resort with a $2,900 luxury unlimited pass.

The Mega Pass includes unlimited skiing and riding at Sunday River, Sugarloaf and Loon Mountain, unlimited preferred parking, unlimited tuning, unlimited use of a season-long ski/snowboard locker, unlimited use of Sunday River's tubing park, plus retail benefits and two days of First Track early lift access for four people and use of the luxurious, private ski suite located in the South Ridge Base Lodge.

"We wanted to dedicate a pass product to the 50th celebration that was synonymous with the best that Sunday River has to offer," Jim Costello, director of sales and marketing, said in a press release. "The Mega Pass is a premium product and provides its pass holder with special access to our best amenities and services. It is the ultimate resort pass."

Skiers and riders who have already purchased a New England Pass and want to upgrade to a Mega Pass, the cost of their 2009-2010 New England Pass will be deducted from the $2,900.

Sunday River intends to celebrate its 50 years of skiing on Dec. 19 with a kick-off birthday party.
