4. Plitvice Lakes National Park, Croatia
Yes this is a National Park, but it’s large and has so many different amazing sites to see. It is considered to be the oldest national park in Southeast Europe and the largest in Croatia.
The beauty of this massive park lies in its 16 lakes, each connected by gorgeous waterfalls that run through the mountainous central region of Croatia. It is considered a must see attraction, but few people know of the wonder that this country has to offer.
