Oh yeah, on the west side, there's a nice hidden downhill run which you can try to find. Burnhamthorpe to 401 on east side of river. Haven't tried west side of river. Is now in worse than ever condition due to infringing construction and heavy rain mud slides. I believe the section north of Eglinton has seen the worst.
Some sections are now insanely close to the cliff edges over the creek.
Some sections are completely washed out, and you have to hike up and around off your bike. Baby head boulders and heavily rutted wet clay make it hard not to dab. I wouldn't recommend riding these trails after a heavy rain. When you get back to Burnhamthorpe, ride north again but along the west side of the creek, all the way to Eglinton. Toronto - see my review.
