Outdoor recreation professionals have long sought to impact environmental behavior of participants. Mindfulness and nature connection have recently been explored as possible constructs to impact environmental behavior. The purpose of this study was to better understand the impact of mindful outdoor recreation trips on college students' nature connectedness and ecological behavior. We used explanatory mixed methods approach to explore the relationship between mindfulness, nature connection, and ecological behavior. Quantitative findings suggest that being mindfully outdoors has a positive effect on the degree to which nature is included in the sense of self and on ecological behavior. Qualitative findings support the quantitative findings and suggest that students use mindfulness to connect with nature and to care more for the environment. These findings suggest that the use of mindfulness interventions in outdoor education programming may improve nature connection and ecological behavior.
