As Ali said we went last summer. I was not so impressed with Vaduz. Especially as I think I read that the castle is closed to visitors even if the prince is not there (but I don’t remember 100%). We enjoyed being up on the valley side and having such a great view of literally the entire country.
The place we missed and kind of regret is Balzers. It is a town near the south with a castle on top of a hill. I know nothing about it other than seeing it from the bus, yet it looks cool.
On the other hand, nice photography, awesome journey, all the best, have a good day, keep moving forward.
