The Blue Mountains is a day trip you must take while in Sydney and only 2.5 hours away by train. There are so many activities you can do there: hiking, propelling, mountain biking, glow worm tours, segway tours, horseback tours, quading tours, and the list goes ON!
My boyfriend and I chose to hike the most popular trail, the Katoomba Falls trail that takes about 2 hours to complete. It's a round trip that has a scenic view and leads to a beautiful 150 meter waterfall! (Photos below) You may be disappointed with the waterfall, though, if it has not recently rained. To get down to the trail though, you have to descend down 998 very steep, metal steps, this will take awhile. (Don't worry, there are handrails)
TIP: Bring a picnic, there are many great spots to take a break and snack.
The view from the waterfall, many people stopped to rest and take a waterfall "shower."
