Since the end of the Cold War, terrorist acts have had increasing effects on tourist destinations. Today, terrorism is unpredictable, widespread and mobile, and as such has become a dangerous threat to all tourism activities. Today, tourism is integrated into all spheres of social and economic life. Although tourism is still a fresh scientific discipline, it has become exponentially a mass phenomenon and an economic category that is today the main generator of consumption. In addition to the benefits and advantages that modern tourism acquires through development and growth, it is necessary to face the challenges that terrorism as an increasingly used strategy presents. The term terrorism is often used with the connotation of something that is "morally wrong". With the growth and development of the media, the amount of information about terrorist acts has increased, so today, in society, the news of a terrorist act is considered part of everyday life. The aim of this paper is to explain in more detail contemporary terrorism, the correlation of tourism and terrorism, and to define the impact of terrorism on tourism through selected examples. Examples of terrorist acts in New York and Paris were selected. In order to update the facts, an online questionnaire survey was conducted on a sample of 108 respondents, which aimed to show the extent to which the presence of terrorism would affect the choice of tourist destination. Research has shown that only large and mass terrorist acts remain more lasting in people’s memories. Repulsion towards the destination where the terrorist act was committed begins to decrease after 3 months, while considerations for revisiting the same destination are realistic after 6 months. The results also show divisions of opinion according to the thesis that terrorism can ultimately have a positive impact on the tourism of the destination in question.
