Traveling to new places exposes you to new traditions, culture, society, people, foods and language. These aspects are different form our native culture and excite us the most. We like to learn a lot about these aspects, for which we need to interact with the native people. For this interaction you need to learn their language.
Music, arts, literature and other entertainment means create interest in learning the language of the new place. A language by itself has unique beauty and hence it should be learned. But learning a language of particular region to which you are traveling to will help you in making basic conversations with the native speakers to know important places and their significance, to order native foods, to know the local rules and regulations, to know important details of travel like train/flight timings, fares, etc.
Though traveling provokes you to learn a language out of need, it is also very much useful in getting access to many entertainment activities, apart from literature and arts. As every art and literature is a treasure which helps you in knowing the history of that particular region, learning that particular language will help you in gaining knowledge about the history. This widens your knowledge about the places.
Since, you have a real time experience at a place which is very memorable, traveling plays a key role in generating interest in a particular language and continue the same interest to learn it. Hence, the next time you travel any place, you are sure to not only bring memories, but also some knowledge about a new language.
