Kitch-iti-kipi Springs in the Upper Peninsula is a natural wonder must-see. At first glance, the water appears smooth and placid. On closer inspection, the color ranges from toxic green to a shocking, Caribbean turquoise. Once you are on the self-propelled ferry, look through the glass bottom to see the real shocker. Covering the bottom of the lake are dozens of fresh water springs, violently pouring water up through the white sands. The water is so clear you can see the roiling, churning water easily, despite the depth of the water. Definitely take the time out of any UP trip to catch this place!
