What to see in Montenegro?
Traveling to Montenegro is always a great idea. Here you should definitely see: Tara River Canyon - one of the largest and greenest canyons in Europe, as if descended from pictures; Mount Lovcen - a real symbol of the country, on the top of which is the mausoleum of Petar Negus, the main thinker of the country; Ostrog Monastery - the most famous shrine of Montenegro, an ancient monastery built into the rock, giving it even more grandeur.
Mores and customs
As we have already mentioned many times, Croatia is a member state of the EU, and therefore here the streets are cleaner, and beggars will not meet, and the order is carefully monitored. The comfort of vacationers here is in the first place, as tourism is one of the main sources of income for the country. And the Croats themselves are more "western" people, along with law-abidingness they have a certain closedness, so you should not expect a special hospitality.
Montenegro is somewhat behind in this respect. It cannot be said that the country is drowning in dirt, but the locals may well leave garbage in the wrong place.
