Hello friends!
Starting in a few days I am going to be running a 5-day intro to the outdoors course at the school I teach at, and I am working on compiling a list of outdoors-related films (either short films or full-length movies) to potentially show to them. So, I am asking you all this - What is your all time favorite outdoors-related film / what is one film you'd recommend to show to children/teens whose first time it is in the outdoors?
The films must be rated PG-13 or less, no R-rated films, please!
Thank you so much in advance for taking the time to help!
