Boundary Waters Canoe Area Wilderness: Louse River is a 35 mile lightly trafficked point-to-point trail located near Ely, MN that features a lake and is good for all skill levels. The trail is primarily used for camping, fishing, and canoeing and is accessible from May until October.
I've been there a few times, it's amazing if you're looking for solitude and very few amenities. It's vast and gorgeous wilderness. Where to start... seek an outfitter to help plan your first trip/ route.
I spent almost two weeks, canoeing, hiking and camping. I met two bears, lots of chipmunks, squirrels, birds and mosquitoes. Oh yes, all the jokes about mosquitoes being the Minnesota state bird are well earned. The wild blueberries were in season when I was there so I had plenty of fresh fruit to go with my dehydrated camping foods.
