After taking some photos of Percy's "family" we set off to Katoomba and you can see why they are called the Blue Mountains from the following photo.
I would call this "survival of the fitest". While walking one of the tracks along to the Threee Sisters I spotted this tree growing out of the sandstone rock face and I wonder what lives in this "house". I was not going to put my hand in to find out!!!
And of course the highlight of going to the mountains in autumn has to be seeing the beautiful range of colour in the trees.
