Yes, the terrific North Shore state parks are closed due to the Minnesota government shutdown. Even if you made reservations for that prime campsite a year ago for this holiday weekend, you can't use it. Plan A has gone down the drain.
Where else do you camp? You need a Plan B. For campsites right on Lake Superior, the only options left are private campgrounds and municipal campgrounds. They have already absorbed the overflow from the state parks and are full.
I recommend hitching up your sense of adventure and heading inland for a campsite in the Superior National Forest. To camp the North Shore this is the weekend you need a copy of my book, Camping the North Shore: A Guide to the 23 best campgrounds in Minnesota's spectacular Lake Superior region. You'll find detailed directions and descriptions for lovely campgrounds such as Crescent Lake, Two Island Lake, and Temperance River. If you're willing to go off the beaten path, you'll find free rustic campgrounds along trout streams, on the edge of the BWCA.
As you head through Duluth to the North Shore, pick up a copy of this book at Duluth Pack Store, the Bookstore at Fitgers, or any Holiday Store.
Plan B: Head up the Cramer Road
The lucky folks already camped at lovely Ninemile Lake won't like me for telling you this, but I'd recommend heading to that campground first. From Finland, head east and north on the Cramer Road (County Road 7). The Ninemile Lake campground is about ten miles out of Finland. If all 24 sites are full there, keep heading inland on County Road 7 to check out the rustic campgrounds at Harriet Lake and Hogback Lake. You might end up all the way inland at Kawishiwi Lake, but it will be lovely, quiet, and free.
