The way points of this bicycle route:
This is the one part you may have to dismount... a pedestrian bridge (with ramps) takes you over the CN tracks.
There are still some smallish hills on this route, but nothing like the huge one near St. Clair on Yonge, and they are all quiet streets, so you don't have to take a dangerous route like Mt. Pleasant. Getting over the railway tracks is accomplished by a pedestrian bridge (with ramps) off Summerhill, and once you get to Moore Park Road, a nice journey through Mt. Pleasant Cemetary gets you up to Yonge & Davisville.
