Taking the form of a “narrative of practice”, this article presents a project conducted in 2020-2021 at La Maison Bleue of Parc-Extension (LMB-PX), aimed at promoting the well-being and health of mothers and their children in the context of the COVID-19 pandemic. The project, composed of two initiatives called Club de Marche and Projet Plantes, mobilized practices centred on nature and adventure (PCNA) through group intervention on family health. This project empowered the participants through the creation of new social bonds, an adaptation to the land, and a connection to nature. This article aims to inspire the introduction of PCNAs in new settings. It highlights the role of social workers in influencing the overall health of individuals, groups and communities by prescribing nature outings and advocating for equal access to nature and urban green spaces.
