Wisconsin Attractions

Hi

Anyone from Wisconsin please share me few details about the wisconsin attractions. Actually we r looking for great lakes in wisconsin. We r couples (no kids) planning to visit great lakes. But not sure of the places which one to visit. Can anyone share reviews of Lake michigan and lake superior.
As i browsed in the net, i can see lake superior islands and more waterfalls @ lake michigan.

Can any one tell me which is the best place to visit. Please share me the reviews of great lakes if anyone has visited.

Thanks in advance
