Found it, I think. The access is just 10 minutes North of Flynn's. The road into the trail (N 44deg 41.149', W 078deg 21.537') is a combo forestry/quarry narrow gravel path with tons of ATV/OFSC mapped routes. The only place I could find is at a Y in the road (N 44deg 42.231' W 078deg 24.862') We went up the trail a few km, but were unsure of road access rules. It's pretty soft with all the rain and didn't want to chew it up. Anyone else know of somewhere around the Kawarthas to go? Any Jeep clubs in Peterborough area?
