I'm working on a foot/paddle traverse of the lake country up there and this would form an important link in the route, provided I could get a permit from the reservation.
I've hiked the standard Border Route between Rengo Road (North end of the Superior Hiking Trail) over to Gunflint a couple times. Pretty bushwacky for a "maintained" trail. The BRT guide describes the unmaintained section thru the Grand Portage Reservation as "rough".
Anyone ever been on the unmaintained section? Worth trying, or even possible to follow?
