Just wrapped up a 1000km trip to Ottawa and back!
Highway 509 was absolutely epic (at least compared to anything I've ridden in the GTA). The sign was not wrong when it said 32km of winding roads ahead.
Thanks for the great route. Took 401 to get back to Toronto, big mistake!
The 509 is one of my favourite roads, glad you enjoyed it. Lots of other great roads off the 509 around the Snow Road Station area.
