…and relax. The oil of the Eucalypt trees is what has given the Blue Mountains their name. It creates a blue haze which lingers over the treetops and which can be seen on clear days. Taking a deep breath is intoxicating and relaxing at the same time. Highlights for us were the famous rock formation “Three Sisters”, the Leura Cascades, Wentworth Falls, the Waradah Aboriginal Center and the fact that you can buy a 2hr scenic train ride from Sydney to Katoomba for 5,30AUD per person! That´s unbeatable public transport pricing!
