A few hours drive maybe. Higgins Lake is a neat one, in the past the water was CRYSTAL clear, not so much anymore but still pretty.
Another of my favs is Lake Charlevoix
Best I've seen in a while, as far as inland goes is Lake Gogebic
Not that "big" is important for an inland lake, lots of smaller lakes / ponds are also nice. The Alcona pond on the Au Sauble is very nice. Duck Lake in Interlochen, Indian Lake in Manistique.
I don't know much about southern Michigan, it's not my scene. The further North the better, JMHO.
