Silver Creek Circuit Kinglake 13.5k Medium hike. Bring Poles. This is a circuit walk approx hour from Greensborough drive to Kinglake National Park near Fowerdale. There is a 50 minute uphill to start but not too steep then lots of short steep up and downs. Lunch at a pretty waterfall about half way. After lunch there is a short up and very steep downhill, a creek crossing and just when you think thats it you are met with another steep up and down just to keep you on your toes. Thats why its graded medium.
