This article considers the possible contribution of the "kids in parks" programme offered at Golden Gate Highlands National Park to the professional development of teachers. Focus group interviews were held with teachers who participated in the programme, and an interview with open-ended questions was held with a learning facilitator from the provincial education department. Although the programme has not primarily been developed to focus on professional development, the setting creates an ideal opportunity for the professional development of teachers away from the formal school situation. This research suggests that the programme, and consequently similar programmes offered at other national parks in South Africa, could make a contribution to the professional development of teachers.
