Been 5 times in the last 6 years(went to the Missouri above Peck dam 1 year in the middle). Just got back from there on the 18th, absolutely love the iy, both Gunflint and Ely area.
Bring:
-100% deet, bugs are relatively bad year and we were bothered by biting flies at our final camp, regular bug spray didn't seem to be as effective as 100% deet
-Quick dry clothes but not too many, I typically go with 2 sets of clothes 1 that I wear in and a dry pair in case I get wet + a fleece if its cold(was blazing hot when we were up this year so I didn't even pack the fleece).
- I know many will advise hiking shoes or boots for portages, personally I find a sturdy pair of sandals(Keens being my choice) more than sufficient unless you are really do a lot of long portaging.
-A good book
-Really think over the food pack and what you need and don't need, our first year we packed way too much.
Speaking of food we've found our fairly efficient lunch solution to be tortilla pbj + summer sausage(since it doesn't need refrigeration until after opening). Its fair space efficent and has the bonus of not needing to boil water.
- If you have the option/money Kevlar or to a lesser extent Duralite canoes are nice vs Aluminum, you definitely notice the weight difference on the longer portages.
Out of curiosity what lake are you going in on and taking out at?
