Wondering if anyone has tried this route as a shortcut to get from David to Threenarrows? If you take this it will reduce approximately 4.5,000 portages over Great Mountain Lk. It’s not a marked route on the Unlostify map, but I wonder if that means it is completely impassable. I’m not sure which direction the water is going (if at all) but a look at the topo lines makes me suspect we would be paddling up … has any of you adventurous people tried this route before ?
Go with a group of very strong and experienced paddlers who are familiar with Killarney.
