Trail notes

After the Negro Flat Aid Station on the Caples Creek loop you will have a creek crossing at Caples Creek. If the creek is high with water or you do not want to get your feet wet, please follow the ORANGE RIBBONS down stream a few minutes to cross over the creek by utilizing a fallen tree that you can use as a bridge. Proceed with caution to a tree that has fallen over the creek. After arriving on the other side please follow the ORANGE RIBBONS up stream back to the main trail to the PINK RIBBONS.
