I have skied there 10 or 15 times a year over the last 3 or 4 years, probably more this year since Berthoud is closing. Personally I think it is superior to Vail or Copper or the other big corporate resorts.
The mountain is divided into two major sides, Winter Park and Mary Jane. The Winter Park half pretty much sucks and is just some icy, crowded blues and greens. Mary Jane is incredible, there are some of the best powder stashes anywhere off the Iron Horse chair. The challenger lift is the other major area of interest. There are 8 or 10 long mogul runs that have good corn even in the early spring since they are south facing. Also check out the 4 chutes off the challenger trail, hole in the wall is the farthest to the right and the hardest of the chutes. Its not open much, but when it is it's some of the ballsiest inbound terrain anywhere. Basically you fall and you aren't going to stop for a couple hundred feet and you're going to hit some rocks on the way. At the bottom of the chutes is a big open bowl where a bunch of local kids including myself build some big kickers. There are usually 4 or 5 kickers with nice pow landings as long as the chutes are open, it's good for practicing new tricks. Mary Jane is basically the capital of mogul skiing in Colorado and you can find long, maintained bump runs anywhere on the MJ side of the mountain.
Above Mary Jane is Parsenn Bowl and further over Vasquez Cirque. Parsenn Bowl is pretty windy and the snow is usually pretty crappy and the timberline lift leading up to it always has long lines. Vasquez cirques isn't often open, but it is pretty incredible when it is. We were there on the first day of the season that the cirques was open, and we were up there with a handful of others. No joke thigh to waist deep powder down the huge open bowls, then into the trees dropping 15 to 20 footers like it was nothing at all. It was probably the best run of my life, so if you can get up to the cirque, the 30 minute hike/traverse is well worth it.
Winter Park is about 1 hr. 15 min from Denver if there is no traffic. You have to go over Berthoud Pass which is one of the better maintained in the state and doesn't close too much. I'd definitely reccomend Winter Park if you are considering it. Anymore questions, just ask.
