Permits are required for various activities in the reserves, but no fees are charged. Permits are not required in the Lower River Zone, outside the Bay du Nord Wilderness Reserve's borders.
The Bay du Nord Heritage River Corridor is open year-round. However, certain activities will be greatly influenced by the season and weather conditions.
Note that snowmobiling is not permitted in the caribou winter range from December 15 to March 15. See the Bay du Nord Wilderness Reserve User's Guide for a map of the winter range of the caribou herd.
