The UNESCO heritage listed Three Sisters in Katoomba is the next stop on this private sightseeing tour to Blue Mountains. Three Sisters lookout at the Echo point is the most visited lookout by travellers and it is a natural wonder. As per Aboriginal culture, its a rock formation with many legends behind it and on the north escarpment of the Jamison Valley. The Giant stairway bushwalk at the Echo point is another favourite of our travellers, that gives fabulous views and excitement.
