The Blue Mountains are located around 100km West of Sydney, 2 hours (~$15cad/person, return) by train. They are named that way because of the blue haze that is formed from eucalyptus oil in the air.
We arrived at Leura station at around 11:00am, grabbed a coffee, and walked 25 minutes to the trail. Just before reaching our destination, we were greeted by what we thought were some local "pigeons", but turned out to be really noisy cockatoos. We were amazed to see how common these birds are around the Sydney area.
We first headed West along the Prince Henry Cliff Walk to see Katoomba Falls and some viewpoints along Scenic World's Scenic Skyway.
Then we backtracked and walked further Eastbound, stopping at the Three Sister viewpoint for some lunch.
After lunch we continued East along the trail to catch the train back from Katoomba Station.
On this section, we encountered a few areas where the trail was closed due to damage from the heavy rains and floods over the past few years. We had to detour off of the path and back on the road a few times along the way, but still had some great views.
We took the train back at 16:00, stopped for some yummy Thai food for dinner, and then took it easy for the rest of the night.
