Lower levels: Navigation: |
The trail leads 350m down into the valley, around the valley overhang and eventually up to the Three Sisters. Initially the scenery is open and over the valley floor with white Eucalyptus trees (one of a few trees which shed their bark and use fire to germinate and dominate the forest) but rapidly the ferns envelop us and the canopy seals off the sky - it gets warmer and humid now. Along the way, we learn that it is refraction through vapours from the Eucalyptus trees which creates the blue haze we can see over the valleys (hence Blue Mountains) and also find out about the Australian nasties - the Redback, viruses and Snakes which infest the area. I heed the guides advice and tread lightly...

Taking a
bush-walk is a highlight of any trip away from the city. Today we headed
into a hanging valley which is named as such because it was formed initially as
a wide river which then narrowed and formed a second valley in softer ground
below - the result being a fertile overhang which has gum trees at the top and
tropical ferns at the base.
