Try Cedar Island Lodge on Pipestone Lake, Emo, Ontario.
Cedar Island Lodge webpage
This is ideally located between Rainy Lake & Lake of the Woods, with 60+ miles of long narrow lakes up to 300′ deep to fish.
Trophy fishing in Northwestern Ontario’s premier fishing site! Pipestone Lake is known for excellent walleye, smallmouth and largemouth bass, northern, muskie and lake trout.
Just 50 miles from International Falls, MN, we are accessible by boat or plane. Most guests travel by vehicle to the secure parking area where they are met by our camp boat or launch their own. Enjoy a 17 mile scenic boat ride across a mechanical portage into peaceful Pipestone Lake.
Need not worry about weather knocking you off the lakes and very secluded.
They just reopened in 2011 and offer some unbelievable fishing 6 1/2 hours from Mpls.
PS: I am not associated with them, just know the experience available with a friends cabin just down the lake.
