A TWAT is always entertaining.Plenty up there but a lot of it is separated by long straight roads.
Order a Lake Superior Circle Tour guide. covers a lot of the UP
The attractions are mostly nature/scenery and or old time industry relics/museums
The west end to middle stuff
In no order. the Keweenaw Peninsula
Duluth
Apostle Islands
Porcupine Mountain State Park
The TWAT, that'll keep you entertained on XS's
There's about 15 various waterfall parks.
