Porcupine Mountains state park in the UP is nice, lots of little rivers/small waterfalls and also the commanding Presque Isle River falls. It might be too much like Eagle Creek if you are looking for some different subject matter. It's also pretty desolate there as in bring your own food and such so might not be much fun for the family on an extended stay but might be a good place to stop if you are going over to the Keewenaw. The whole peninsula is pretty interesting and there are fun activities and some touristy stuff too, is it a combo vacation, pictures for you and tourism and fun for the rest?..Evan Clarke
