A while back we set ourselves the goal of visiting 60 countries by the end of 2015. Our definition of 'visiting' is aligned with this country-ticking objective - cross the border and it counts!So when we noticed that Vaduz - capital of the small Principality of Liechtenstein was directly accessible by train and bus from Chur, Switzerland (our location from the last blog post); we couldn't resist the trip to see it. Then after just two hours of sightseeing, we were back in Switzerland, on route to Zurich for the final stop on our four day Swiss rail journey.
