First-episode psychosis (FEP) is a serious mental disorder that predominantly affects young adults. It is a multidimensional and complex phenomenon from which recovery is possible. Some studies show a relationship between recovery and the use of interventions that help mobilize personal and environmental resources. Among these are nature and adventure-based practices (NAPs). Although these practices are well known for their benefits on mental health recovery, few studies have been conducted on NAPs with people who have experienced FEP. The purpose of this article is therefore to present the outcomes of an intervention project carried out in nature with young adults who have experienced FEP. Outcomes show that the intervention was beneficial for clinical, existential, functional, physical, and social dimensions of recovery. Considering the nature of this project and its limitations, this article highlights the potential of such approaches in social work with people who have experienced FEP.
