Is a feature within Coach Wood Forest. At its entry, it is almost totally filled with the Soft Tree Fern, Dicksonia antarctica. Within this enchanted forest, there is a mature Anchor Vine,Palmeria scandens, that has a girth of 20cm and has wrapped itself around a tree very tightly so it formed a spiral ribbed tube nearly one metre high, before it climbed 20m plus into the tree canopy above. This amazing natural sculpture has been dubbed The Serpent. Both features named by Michael Keats and Brian Fox on a Bush Club walk, 20th August 2012. This ravine is located 500m south east of Galah Trig, access via Galah Mountain Road.
