This dissertation explored the experiences of 12 adolescent girls in a nature-based therapy program, known as Ramapo for Children, in Rhinebeck, New York.  Three qualitative interviews, and supplemental quantitative data, were used to gather information on the girls’ experiences in the program and in nature, including the therapeutic benefits of the program and relationship building with staff and peers. The most salient components facilitating personal growth and a positive experience in the program were the relationships formed and opportunities to be in nature.  The greatest difficulty in the program was adjusting to nature and being physically active. This study provides long-term information based on a diverse population that is minimally covered in the current literature, as well as concrete program suggestions for nature-based therapy programs for adolescent girls.
