Quetico, Sylvania, BWCA, Voyageurs or ????
It depends on what kind of trip you're looking for and how much portaging you want to do.
I've never heard of Sylvania but I've been to the other 3, assuming by "Voyageurs" you mean "Voyageurs National Park".
If this is your 1st time portaging a W/C, can you handle it alone?
Voyageurs will have few/no portages but very large water AND plenty of motor noise.
Q portages are generally rougher and less "improved", though with careful planning and sticking to large lakes they can be minimized.
BW portages are generally easier then Q but there will be more people. Again if you stick to the larger lakes (the border), portages can be reduced.
We generally go to the BW just because it's a lot easier and cheeper. You'll need a permit, RABC and fishing license to go to Q from MN. If you go through a Northern entry you don't need the RABC.
