The Northern Ontario Resource Trail is a mainly gravel road in the Canadian province of Ontario, which travels north from Pickle Lake to the northern shore of Windigo Lake. It links several winter roads and ice roads that serve communities in extreme Northern Ontario to Highway 599.
The first 60 kilometres of the route, from Pickle Lake to the Otoskwin River, also held the tertiary highway designation of Highway 808 within Ontario's provincial highway system from 1966 to 1983, before it was decommissioned.
On December 6, 1966, the northernmost 60 km portion of Highway 599 from Pickle Lake to the Otoskwin River was re-designated as Highway 808. This designation lasted until 1983, when it was decommissioned as an official Provincial Highway. The southernmost 3 kilometres (2 miles) of the trail is paved, while the remaining length is gravel. The road is maintained year-round, due to its importance as a connection to ice/winter roads connecting to remote First Nations communities in the Kenora District.
This road is extremely lightly travelled, and is in a very remote section of Ontario. It is advised that one fills up with gasoline and supplies, and checks weather conditions before travelling down this road. A spare tire is also a good idea, as it may be several hours (at least) for assistance to arrive. Cellular phones are useless in this area since there are no nearby cell phone relay towers in the wilderness.
