DETOUR: Discover Europe Through Opportunities Using Rail is a project aimed at young people who have little or no access to European mobility. Going abroad is a unique experience, capable of transforming the lives of those who benefit from it. However, Parcours le Monde's experience in supporting young people with fewer opportunities has shown that not everyone is ready to take part in projects such as those offered by Erasmus+ or the ESC. For some young people, who have never left their neighbourhood, village or family, the idea of going off on their own, without a familiar figure, is a major obstacle. Indeed, for the most vulnerable groups, leaving without support is unthinkable. With this in mind, we decided to submit a project as part of the Discover Eu-Inclusion programme. From the outset, we have been working with local social and youth organisations, and thanks to this opportunity, we want to offer them a 7-day mobility project by train. Two accompagnying adult will be responsible for a group of four young people, and this mobility will be co-constructed with the young participants, their accompanying adults and Parcours le Monde. The objectives of this project are as follows Strengthen the skills of young people and professionals: Involve young people and professionals right from the start of the project, from choosing the destination and itinerary to booking transport and accommodation, managing the budget, providing guidance, etc. Offer a first experience of European mobility to young people who are the furthest away: Target our main target group, in other words young people who are the furthest away from mobility, and enable them to open up to Europe, become more independent and discover interculturality. Promote European mobility within youth organisation: Develop a culture of mobility within organisations that support young people with fewer opportunities.
