L'ENVOL welcomes seriously ill children aged 6 to 17, suffering from a variety of pathologies (cancer, rare diseases, chronic illnesses...) to its multi-pathology stays, free of charge, where they enjoy a break from illness and take part in adapted, varied and fun activities. Coached by recruited and trained volunteers, including doctors and nurses, sick children become children again, gaining in autonomy and resilience, and their caregivers benefit from respite time. They learn about the stays via a network of more than 80 partner hospitals and medical facilities that identify children in the weary phase of illness.
