Ferntree Gully is a highly scenic rainforest area 17 kilometres north of Rylstone. There are many walking tracks at Ferntree Gully that take you down into the cool narrow fern-tree studded valley floor, and/or around the top edge of the rocks where you can get an overview of the valley and the unusual rock formations on either side. A loop walk takes you through unique plant communities ranging from western dry sclerophyll to lush rainforest in and around a deep and narrow gully of eroded sandstone rock.
