boner - i would draw you a map like 70cbk0 did but I don't know how to do that.
Truthfully, there aren't a lot of twistys around here even though it is fairly hilly and we have the escarpment running through. There is Forks of the Credit road as a notable but is not open due to construction. The Hockley Valley Road might not be out of your way and it is twisty and pretty nice.
There is one small piece of the route that I could suggest. It is very pretty and has lots of ups and downs. Paved road and seldom any traffic. Just a bit west of Acton is 6th Line Nassagaweya which you can pick up at a village called Blue Springs on Hwy 7 or further north as 7th line Eramosa at Everton and take it all the way down to Campbellville Road. Very nice. My fav way to go south around here, a huge drop down the escarpment just before Campbellville Road. Gear down and use engine compression to keep from going too fast. It is a LONG STEEP hill with a great view.
Watch for wildlife, deers dart across the road and there are often big turtles crossing that might be on the road.
Turn west on Campbellville Road, go up the hill and over and then take the left fork that goes under the 401. In a couple of km you are in Cambellville. There is an eatery that might suit your needs. I think called the "Icebox", at the corner where you come into Campbellville (and that road is twisty by the way) and you will notice it right away since usually there are LOTS of bikers parked there. Good food. Just north of the gas station which is on the north-east corner. Depending on the time of day, it gets pretty busy, you might not even get in. But you can get a take out coffee there and chat with the other bikers and look at lots of pretty bikes.
Then get back on the Campbellville Road west until it turns into Gore Road and that gets you to Cambridge.
BTW - if you want to go further south one day, at the end of 6th line Nassagaweya at Cambellville Road, go just a bit west and pick up the top end of Appleby Line through Kelso and you can go all the way down to the lake. Appleby has a spectacular and quite dangerous twisty as it comes down off the escarpment - fabulous.
