I’ve been to the blue mountains many times but never ventured in to the bush so this was a great first experience. It really felt worth the 20-30 minute round trip. The descent was maybe 10 minutes with two young kids in tow, going down was easy for grown ups but harder for kids. Coming back up was a struggle for me and I stopped to catch my breath a couple of times (if you’re out of shape be prepared for sore legs), my 5 year old was telling me to hurry up going back up! Almost 3 year old was challenged but determined. I wouldn’t take a child under 3 unless you are prepared to carry them if they can’t or won’t go on. Waterfall was beautiful, water was clear, super cold and refreshing. There’s no bins down there so if you bring any food make sure you bring bags or something to take your garbage with you. Great fun would go again. Very busy though so might try a weekday next time.
