Make your way through an old-growth jack pine forest connecting the Marten River Campground and Day Use Area with the Marten River Group Use Area. Please note that you will need to turn back before reaching the Group Use Area unless you are staying there yourselves. Look for witches’ brooms, squirrels, and the elusive pine marten while you travel. The trail is generally flat but includes some gentle slopes. About one quarter of the way along the trail, there is a somewhat steep downhill access to the lakeshore, so you can hike the Jack Pine trail to that point and then walk back along the lakeshore if you wish; this route isn’t  suitable if you are cycling.
