Took 1 hour at 120km to get to Tim Hortons just north of Weber's from Newmarket on Hwy. #11 North.
Dropped a car off at the take out. Exit off Hwy. 117 to Baysville. Went west over bridge and the right immediately on to High Falls Road.
Proceeded N. on Hwy. 11 to Port Sydney Road. Stayed straight (did not go up the hill). Just before first intersection there was a steep driveway down to small parkette. Could see water through trees. This parkette is just south of Mary Lake.
Took 1 hour to first portage of 75m. Portage on left. A lovely otterslde with a huge keeping hole at the bottom. A big step up to take out, easy portage, easy put in.
1 hour to next portage. Portage on right (100m). Could take out either at portage sign, or with checking, could sidle down river right to take out. Easy portage and put in.
1 hour to take out at High Falls. Big step up, and 25m to cars.
30 min round trip shuttle to get cars.
Add 1 - 1.5 hours if water is low or you are in head winds.
