Blue Mountains: Get on track
7 of 11
The Three Sisters, a trio of rock formations which overlook the cliffs of the Jamison Valley, is one of the most notable sights in the region. The Blue Mountains is also home to the world's steepest funicular railway, Scenic Railway, which travels through a cliffside tunnel and showcases views of the rainforest as well as the Three Sisters.
