March is high season in the ski industry our west. Aspen Ski Company mountains have been somewhat skunked on the snow the last few winters.
So it could be iffy. I have usually gone at the end of March or begining of April.
So where to stay, and how to enjoy the best of skiing.
Ok I'll tell you my favorite option. Stay in Aspen if at all possible, best restaurants, night life shopping, women,etc. Want to save some dough on eating and the night life, cozy up to the locals, they know where the good and real times are and for a lot less. The Gant is a good place to stay and reasonable when compared to other Aspen accomadations, but a little out of the way. They do have an excellent shuttle service, that will take you where you want in Aspen, and if you call they will usually pick you up where you are or will direct you to a spot not too far away. A great convenience.
Aspen has this really efficient and free [ during montain operation hours ] shuttle service. Aspen Highlands is 5 minutes away, buttermilk 7-8 minutes. Aspen Highlands is a great mountain, and the favorite of the locals. I usually ski there for about 2-2.5 hours in the early am, and then take the bus back to Aspen, and ski Ajax during the 11:30-1:00 pm lunch time, less crowded then. Then at about 1:30 I go in for a snack and ski another 2 hours or so. That's plenty.
While Snowmass is wonderful, it is also very large, and can take as long as 1/2 hour to get there, so that's anywhere from 40-60 minutes travel time round trip. But if you are going to be there for at least 5 days of skiing, devote one day to Snowmass, get there early, and get off the shuttle bus at the Two Creeks stop,it is about 7 minutes less travel time, and the the high speed lift is about 50 yds away. If you go to the Aspen Village stop, you have to walk all the way through Snowmass Village to get to the slopes, and it takes quite some time and early in the morning it is a considerable hike in ski boots.A good warm up however.
By going to Two Creeks you can work your way over to Snowmass Vilage, have lunch there or mid mountain, but you avoid some serious early moring hassles and lift lines that occur at the base of the mountain near the village.
This strategy assumes that you want the more authentic Aspen experience, rather than the obvious and more plastic experience of Snowmass village, you are above an intermediate skier in performance [ Ajax Mtn. has very little intermediate skiing, and no beginner skiing hills, ] and that Aspen Highlands with its redesigned and expanded base area, and Aspen itself will be the major focal points of your skiing experinces, which can be wonderful.
Well I hope this helps, have a great vacation and remember.......
