My family went for a hard day walking at macritchie reservoir wanted to visit the HSBC TreeTop Walk. The journey to the bridge was 4.9km. We spend 1-4.30pm just walking and walking (so much complain from me) We even lost our way after going thru the TreeTop walk ... thankfully my mom didn't come along. Lots of walking in conclusion we had a good time though everyone was sweaty and exhausted. Kinda of positive that I think will not be back there so so soon.
