Breckenridge or Vail/Beaver Creek??

[High Altitude]

Personally, I enjoy the Breck/Frisco/Dillion area much better. Much more variety of places to go, things to do etc.... Doesn't mean vail isn't nice, it is.

I lived in Frisco for a year and currently live in Avon. One thing I can say for sure is that it is a lot colder in Summit County, especially in the mornings. I'd say on average 10 degrees and Eagle County gets progressively warmer as you go down valley. This isn't that big of a deal in the dead of winter or in the middle of the summer, but the cold weather drags on a lot longer in the spring in Summit and summer tends to hang on longer in the Fall in Eagle County. When I lived in Frisco I remember watching the aspens across the street leaf out in mid June. And I lived on the sunny side of town. That is not to say that it isn't cold in East Vail.....

There are things I miss about Summit County (much better for road & mountain biking and cross country skiing / snowshoeing) but as a professional in my 40's, Eagle County is much more livable from a peer standpoint. In particular, I'd check out the Wildridge development in Avon and the Singletree development in Edwards. Both probably have at least a 90% year round professional population. The comparable area of Summit County is Summit Cove.

I would note that although Frisco seems like a very cool little town (and I'm not saying it is not), the majority of houses are actually second homes for residents of the Front Range. It can be a ghost town during the week and the cars all roll in on Friday. If I lived in Denver and was looking for a second home, I wouldn't think twice about having it there. But my first home is in the mountains and I am very happy in Avon.
