Pickle Lake is a township in the Canadian province of Ontario, and is the most northerly community in the province that has year-round access by road. Located 530 kilometres (330 mi) north of Thunder Bay, highway access is via Highway 599, the only access road to the town from the south. More northerly communities rely on winter roads for access and are cut off to land travel in the summer. Highway 599 meets the Northern Ontario Resource Trail, formerly Tertiary Highway 808, at Pickle Lake.
