Let’s discuss some practical information that may be useful for you during your stay in Montenegro as a tourist.
Montenegro is a candidate for entering the European Union. Currently, if you are a permanent resident of the European Union, United States, or United Kingdom (or have their valid visa), you can stay in Montenegro up to 30 days without any other special visas or documents. Passport holders of other countries have either 30 days in Montenegro without a visa or 90 days over 180 so check the rules for your country.
Montenegro’s currency is euro. On the Adriatic coast, you can pay by card almost everywhere (except bakeries and some bus stations). But if you go to national parks like Durmitor or Prokletije you should better have some cash with you.
During your stay in Montenegro as as tourist, you have to pay tourist tax which is 1 euro per day for adults, 0.5 euro per day for teenagers 12-18 years old and free of charge for children younger than 12 years old. If you stay in hotels, usually there is nothing to worry about, they will pay it automatically for you and print your confirmation. But if you need to pay it yourself for some reason, you should go to Tourist Information point (they can be easily found in all cities and towns), tell them your name and address and have this tax paid.
There are three mobile operators in Montenegro: Telekom, Mtel, and One. It is convenient to buy a SIM card with a tourist prepaid option. For example, Telekom suggests tourist prepaid options for 7, 15, and 30 days. It can be prolonged if necessary and includes phone calls, internet, and SMS. Certainly, in hotels, cafes, and restaurants you can use Wi-Fi almost everywhere.
If you plan to explore the national parks of Montenegro, especially the mountains, offline maps (like Maps.me, these offline maps work well here) will be useful for you because sometimes there may be no stable Internet connection available.
