The onion river is well known to those that frequent the north shore, but often overlooked by those that only visit once in a while. There is a trail the follows alongside the river and it provides a great view, the best way to experience this river is to get your feet wet and walk up it. There are numerous waterfalls to be found and the river narrows considerably further up the river. I typically follow the river until I reach a ATV/Snowmobile bridge and then take the trail back to my car. On the way back make sure to stop at the overlooks and take in the views from above.
