We're going to Breckenridge for the first time April 16-22 with 3 kids (9,11, & 12). We'll ski (I know it's late in the season to ski, but it's the time we have) and are looking for some other activities do do as well. We'll have a car, so can do day trips. Are there any hot springs relatively close? I just read that you can fly fish too, which my sons really want to do. Suggestions on where to do that? Other fun ideas with kids?
