We are considering a mid-April trip to France and my son (who will be 10 at the time of the trip) really wants to go to the Alps. I know there is a ton to do in both winter and summer, but what about spring? We're probably not interested in skiing, but more interested in exploring the area, hiking, enjoying nature, checking out the views, etc. Will it be too cold or snowy to enjoy non-skiing outdoor activities? Thanks!
