Those behind the Actif Woods Wales project believe simply being out in the fresh air can help alleviate common medical conditions, including depression, diabetes and arthritis.
Woodwork, plant and animal identification and fire-lighting are just some of the activities on offer at sessions in Aberystwyth, Ceredigion and Rhondda Cynon Taf.
It's hoped the benefits of being outdoors will work alongside modern medicine to improve people's physical and mental health.
