Considering trip out west including Beaver Creek with my wife and 17 and 9 year old sons. I have spent time in Beaver Creek during the winter. I am concerned that there won't be a lot to keep my kids happy. They have never hiked but they could. We could bike ride, horseback riding, etc. Thoughts of activities and amount of time? We plan on flying home from Denver. Should we stop in Breckenridge for a day or two? Thanks for your help.
