Good snow, fun pistes, excellent night life
Not much diversity in runs
Sierra Nevada is a fun place to be.
It is not particularly big, but has a good assortment of mostly red and blue runs. The scenery on a good day is stunning.
The crowd there appears to be overall friendly and good-spirited.
The resort has very good conditions for skiers, from the solo skiers, to big groups and families.
Night life is wild (although it usually kills your performance on the slopes the morning after.) ;-)
It can be tricky on some windy days, when big parts of the slopes must be shut off and in recent years it has been getting more and more expensive (although it still is a relatively cheap place to ski).
Not for the big mountain, highly adventurer skier, but definitely worth a visit with a group of friends for a fun all-around ski vacation.
