The Blue Mountains - never heard of them but so glad we came. Two hours out of Sydney is a high sandstone plateau, carved into canyons and cliffs by rivers which now tumble thousands of feet over the edges. Covered with trees and plants only ever seen in the UK in garden centres, the views are spectacular. Standing looking over the edge, you just see miles and miles of hazy blue forests interspersed with high red rocks. A hundred years ago, men were challenged to develop the most daring and spectacular walks for the new tourists who flocked here to listen to jazz. And so there are paths which wind their ways round the cliff faces half way up the cliffs, lookouts leaning out over the edge, ladders and steps to rainforest and waterfalls, pools where you can swim and the loudest ever cicadas in the world. take a look at some of the photos, it's a really brilliant place for walking.
