Many of the top-rated family-friendly ski resorts across the US and Canada offer kids ski and/or stay free programs for families with young children. This is a great way to cut some of the brutal expense out of skiing with kids.
We published a Where Can Kids Ski Free in 2010 list last year and it was so popular that I just updated it with 2011 promotions. Good news, many resorts are still offering great programs for families. A special shout out to Mt. Bachelor in Oregon where kids under 18 (!) can ski free all season long when accompanying a full paying adult with a multi-day pass.
