At 5,333 square miles, Montenegro is one of the smallest countries in Europe. But with crystal clear lakes, pretty bays, the deeply-blue Adriatic Sea, gorgeous rolling highlands, and charming Venetian villages, Montenegro is also one of the most beautiful places in the world. In the past, tourists preferred other more well-known Mediterranean countries to visit. That meant Montenegro’s beauty was a well-kept secret. With an abundance of natural wonders, sites of historical interest, and fabulous nightlife to greet visitors, it’s no wonder many are flocking to memorable Montenegro.
