The recent pandemic has moved mountain areas back into the center of political and academic debates, portraying a great opportunity to think about a restart project. With the prospect of enhancing the mountain potential, post-Covid tourism can promote an extensive regeneration of places and communities. In this light, the binomial slow line tourism (paths, tracks and cycle lanes) and social inclusion can turn into an opportunity for a unitary strategy to relaunch territories. To explore this possibility the case of the Trekking Walking Cycling for Inclusion (TWIN) project is being analysed, representing a replicable model, designed to transform fragilities into a strength.
