Don’t be totally scared away from Sylvania. You may still find it to be worth experiencing. One thing I really, really liked was that it is all old-growth forest, because that is something that is virtually impossible for most people to have access to nowadays. For example, I’ve seen patchy hemlock groves in Wisconsin that cast incredibly dark shade, but the trees are tiny in comparison to those in Sylvania. To walk around in a very, very dark forest of big hemlocks with a thick and spongy mat of cast needles underfoot (there are no earthworms to get rid of the leaf litter - and how many people even know that these worms are invasive species and that their absence is another quality feature of these old woods?), is really amazing, the first time you do it. And on our last day there, we took part of a morning to hike a trail where a particularly helpful ranger told us we could find the largest white pine he had ever seen. We found that tree, and also a great many others that were almost as big.
I might also mention that trying to camp with a tent in a truly undeveloped northern forest of lesser maturity often can hardly be done without leaving a mighty big footprint - literally - in clearing/flattening a place for your tent, so Sylvania with its designated campsites has that advantage. It’s fun to read about old-time northwoods camping, and the way people built thick beds of balsam boughs to sleep on, pitching canvas tents right over the top, but nowadays we can’t afford to be that destructive. I guess that makes a good case for ditching the tent and learning to sleep in a hammock (screened and roofed, of course).
