From Big Bay paddle out the west entrance of the bay along the northern shoreline. Head north at the entrance and follow the shoreline to North Cape. Paddle east to Dead Bird Beach. A short, unmarked portage through the rye grass brings you into the back lagoon of the NW arm of Big Bay. This portage is short at high tide; it is longer and muddier at low tide. This loop can be done in either direction and takes 3 to 5 hours. Be cautious when paddling along the outer coast, especially at North Cape.
