Longing...
Cetinje seemed rather boring to me. If you are not interested in Orthodox values, then, in addition to the famous Cetinje Monastery (the main goal of visiting all local excursions), you can visit the museum - the former residence of the Montenegrin king, wander along the ruins of some kind of fortress. In general, to get around the town and see all the most beautiful things in it, it will take an hour, well, an hour and a half with a visit to a souvenir shop and a photo session with a live local “attraction” - blacksmith Bogdan, hitting an anvil with a hammer on the central Cetinje square. You can go to the Church of the Nativity of the Virgin, located near the monastery. That, in principle, is all the Cetinje "entertainment". Personally, I will not go here again.
