I was in hamilton last year briefly for a quick ride and ended up wandering on some trails near the freeway... I also ended up riding some crazy urban down hill which resulted in me dodging cars at 60k but its all fun till someone gets hurt Apparently there are hidden dirt jumps somewhere near the lakeshore... but other than that unless ur a bmxer, your out of luck (N)
I ride the Dundas Valley Conservation area - some good hills but nothing huge. Lots of trails though. Inflow is great and 26" no problem. Also Kelso has some great runs as well. There was a DJ area in dundas but they flattened it. Probably not rebuilt yet.
I'v ridden out to Dundas Valley and rode the main loop but but after riding out there from gage park i was too tired to enjoy the ride as much as i should have.
