When it comes to tourism it is often difficult to define it due to its uniqueness, numerous features that define it and the sectors it affects. There is no one universal definition and this is where the problem arises because many researchers have their own definitions and views of tourism. Of all existing definitions the UNWTO one is the freest in the description of tourism and therefore most applicable to today's times when tourism is in its postmodern state when attempts are made to minimize mass tourism and the development of selective forms of tourism is encouraged. One of selective forms of tourism is festival tourism which can be described as a trip with an ultimate goal of participation in festivals and in which festivals are the main motive of the trip. Participating in festivals can include visiting various events, concerts, exhibitions, competitions and socializing with other festival participants. The festivals themselves are generators of a large number of people of diverse profiles because they are often deeply rooted in culture, history and tradition and can be of different types such as: music, religious, historical, cultural, film, art, food and drink festivals and many others. They often have a direct and intense influence on their environment, and this influence can be negative or positive, which is why the organizers must be very attentive to their environment if they want their festival to succeed. When it comes to the existence of festival tourism in Istria, it can be said that this form of tourism has been present for decades thanks to its rich cultural heritage, nature, gastronomy, wine, olive oil, music and many other factors. Festivals are actually the ideal way to experience all of this in one place. Over the years, Istria has hosted various big festivals that have placed it on the world festival scene. The Teran and Truffle Festival in Motovun can be singled out as an example of a healthy festival that develops from year to year. The Terran and Truffle Festival in Motovun is a young festival that develops year by year in order to adapt to its visitors and provide them with the best accompanying offer along the way. The festival also has a great influence on the development of the destination and thanks to the festival Motovun is recognized as a gastronomic destination with a quality offer of Istrian cuisine, wine and delicacies. The same is confirmed with the fact that thanks to this recognition, Motovun generates visitors even outside the official summer season.
