Kayakers unable to paddle around Cape Decision because of bad weather use the Affleck Canal Portage Trail as a safe alternate route. Both trailheads are marked with red and white portage diamonds and the trail itself is marked with blue diamond trail markers. Because the trail is in designated Wilderness, it is maintained at a primitive level. It is only lightly brushed and sections can be very muddy.

The southern trailhead is at the very northern end of Affleck Canal. The trail winds through forest and muskeg for 0.75 mile up to a muskeg saddle. From the saddle, the trail descends to a beaver pond, then goes through a muskeg to a second beaver pond. The trail crosses the creek and continues through timber to the mouth of the creek in Petrof Bay.

This trail connects Affleck Canal with Petrof Bay and is primarily a portage trail for canoeists and kayakers. Plan for two days to complete the route.
