Despite the rising trend of integrating nature and movement into talking therapy, the extent of empirical support remains limited. This study explored the effects of a walk and talk intervention on adult mood and well‐being using a multiple baseline design with pre, post and follow‐up assessments. Five adults (3 males and 2 females) from a technology company took part in a walk and talk intervention lasting approximately 6–8 sessions. They completed self‐report measures at baseline, post‐intervention and follow‐up, with semi‐structured interviews conducted at follow‐up. Results showed a reduction in psychological distress and an increase in well‐being for all participants from baseline to follow‐up. Qualitative data from a thematic analysis supported these findings: participants found the natural, calming effect of the outdoors, combined with the movement of walking, facilitated a sense of freedom to express themselves and, in doing so, maximise the benefits of the therapeutic space. These included gaining a broader perspective, heightened self‐awareness and greater acceptance of oneself, others and life's challenges. This study offers real‐world evidence supporting walk and talk therapy as an effective intervention for adult well‐being and mood.
