Moon Lake Trail is closed until further notice.
The lake and campground remain open.
Parks Canada has closed the trail because there has been an increase in black bears frequenting the area.

Park officials are also warning about more bears around the Grey Owl Trail.
They are asking anyone going down that trail to be cautious when in the area and make lots of noise while there.
