Planning a European getaway doesn't have to mean leaving the kids at home with Grandma. In fact, Europe has a slew of places to visit that are just as fun for kids (and kids-at-heart) as they are for bona-fide grown-ups. On the agenda: ice caves, train trips, and (no duh!) LEGO.
From glacier hiking to train excursions, these one-of-a-kind trips will do more than just keep them occupied.
