This paper presents a mixed-method investigation of client's perceptions of a good adventure sports coach. Semi-structured interviews were analysed thematically, and the findings used to inform a subsequent larger survey that sought to verify the importance of the themes identified in the interviews. The findings draw an alignment between the attributes of good coaches in traditional sports, as reported in previous studies, and those of adventure sports coaches. However, they also identify three additional attributes that are critical for good adventure sports coaches: (1) in-depth knowledge of the adventure sports environment, (2) a very high degree of individualisation, and (3) an explicit focus on developing the participant's confidence. The implications for training adventure sports coaches are discussed.
