Plitvice Lakes, Croatia
This incredible site hosted one of the most fierce battles during the Yugoslav wars. Now it has been rebuilt and has been de-mined. It is one of the most important tourist attractions of Croatia, and somehow remains a not so crowded place. There are only three average hotels inside the park (which were used as barracks during the war) and a lot of visitors stay at the hostels in Plitvicka Jezera. You can read more about the history and geology of the national park atwikipedia or the officialweb site.
