Lyrebird Dell is home to a sandstone cave beside the head waters of Gordon Creek near Lone Pine Ave, Leura. The cave provides shelter for a lovely picnic area (with a couple of tables). There is also a waterfall next to the cave. The cave at Lyrebird Dell, was used as an Aboriginal shelter from (at least) 12 000 years ago, this has been dated from artifacts found in the floor of the cave. Dell is an old English word that refers to small wooded valley. A great spot to rest and enjoy the area.
