Curiously, while tourism is cited as the world’s largest industry (UNWTO, 2016), it is simultaneously a fragile industry that is highly vulnerable to the impact of the ongoing threat of terrorism. Internationally, terrorism influences the tourist mind-set in a number of ways, in particular it creates fear for travellers and causes economic and social impacts to change the behaviour of people and dissuade them from visiting certain places in the world. Thus, the impact of terrorism has caused tremendous damage to the travel industry. A number of countries which previously depended quite heavily on the tourism industry are suffering in terms of economic development.\ud \ud This paper discusses critical issues related to terrorism, that are faced by travellers to religious and sacred sites. The paper will illustrate the impact of recent terrorism phenomena upon travellers in two ways: first, the potential personal hazards to travellers caused by terrorist incidents; second, the impacts caused by stringent anti-terrorism laws and security measures, to travellers while they are in transit.
