Set out around 8am from the top of the Golden Stairs and arrived at the Castle around 945am. Coming down is mostly easy and the middle section through the forest is nice and mostly flat with a slight uphill effort to get to the castle. Scramble to the top is rather easy when you find the right section to climb. The hardest part was the climb back up the Stairs at the end. I was carrying a 12kg pack for training but is rather hard regardless. Take some rests on the way back up and you will get there fine but you will have some tired legs. Took us 3.5 -4 hours round trip. View on top of ruins was amazing.
