Prague is one of those cities where you can just walk and enjoy, but some highlights you shouldn’t miss are exploring Prague Castle (the views are worth it), walking across Charles Bridge early morning or at sunset, and wandering around Old Town Square to see the Astronomical Clock. I’d also recommend getting a bit lost in the Lesser Town streets, visiting a local café or pub for Czech food and beer (it’s genuinely great), and if you have time, a river cruise on the Vltava is a relaxing way to see the city from a different angle.
