Last year I visited Copenhagen. It was not my first visit to the city - I was there in 2015 - but it was the first time I tried out its metro. I was staying in Odense, Denmarkâs third largest city, but it was pouring rain there, and since it was a public holiday, all museums, galleries etc. were closed. Of course I could stay in and read a book but I figured - why not hop on the train and go to Copenhagen? Even if it was raining there too, at least I could explore their metro
