Fantastic walk with amazing views. We got the scenic railway into the valley and walked to the ruins. A bit of a scramble across the landslide section of bout 500m but other than that it’s a pretty easy walk. We had our 13 year old plus I have average fitness at the moment but did it comfortably. It’s about 2hrs each way. Got the sky rail back up the hill. Also a small hill climb of approx 600m to the ruins but take ur time and it’s pretty easy. Beautiful country. Take some water, snacks & a coffee in a flask and u’ll love it. Be careful not to miss the track off the boardwalk at scenic world. After you get off the train and just past a few displays the trail is off to the right.
