Turn off Brownhill Creek Road https://adelaidehillclimbs.wordpress.com/2013/05/30/brown-hill-creek/ about half way up, and you’ll cross a small ford, and start climbing up a particularly nasty one-way hill. An average of 8% doesn’t really convey how hard this climb is, The first 900m average 11%, with a couple of sustained sections over 15%. Even worse, the road is incredibly rough. About as rough as it gets whilst still being tarmac. I imagine that somebody paved it forty or fifty years ago, and then seeing as only a couple of people live on the road, nobody every thought about it again.
The streetview cars didn’t even go up Brownhill Creek, let alone Tilleys Hill, which is a pity, because it’s very pretty. I suppose you’ll just have to go and climb it yourself.
Anyway, on to the second part of the climb. Once you’ve covered the first kilometre, life gets a lot easier, even if the road gets rougher. There’s a brief dip, and then the last 600m or so are comparatively easy – at about 7%.
This climb ends at a dead end, so you’ll have to turn around and go back down the hill, which can be a little hairy. I was getting muscle cramp in my hands keeping myself to 30kph with brand new brakes.
