This paper presents a case study of a private preschool in Thessaloniki, Greece. The school, located at the unique setting of an educational farm, has a curriculum focus on environmental education. An analysis of teacher interviews and lesson plans in the span of three years presents insights into the barriers teachers faced in implementing their environmental education curriculum, and the developments that occurred within this timeframe. Environmental education was found to not just be "a walk in the park," but a personal growth journey for the teachers and the school as a whole. Teachers' experiences implementing environmental education did not only improve their teaching methodology overall, but created a community of practice within the school.
