The Blue Mountains in Australia are a stunning destination, home to iconic landmarks like the Three Sisters, Giant Stairway, and Honeymoon Lookout. The Three Sisters, a striking rock formation at Echo Point in Katoomba, are best admired at sunrise or sunset, with changing light highlighting their beauty. Nearby, the Giant Stairway offers an adventurous descent down 800 steep steps into the valley, connecting to scenic walking trails such as those leading to the Scenic Railway. For a quieter but equally breathtaking view, Honeymoon Lookout provides panoramic vistas of the valley and the Three Sisters, perfect for those seeking a peaceful escape.
