The wildest corner of the island: a rare, imperiled wet-mesic flatwoods forest of 300-year-old oaks that floods each spring and dries each fall, with short family trails and a daily-open nature center at its edge.
Park here and give this last green stop a few minutes on foot. The Belle Isle Nature Center, run by the Detroit Zoological Society, sits right at the edge of something genuinely rare: one of the last wet-mesic flatwoods forests left in Michigan. State scientists rank this kind of forest as imperiled, and the stand here — close to two hundred acres of it — is among the largest of its type anywhere in the state. What makes it strange and wonderful is the reason it survived at all. Out across southeast Michigan, a hard lens of clay sits just under the topsoil, so the rain can't drain away — and for a century and a half, farms and city alike tiled and drained almost every acre of this kind of woodland to dry it out. This island stand escaped. So it still breathes with the seasons the way it always did: every spring, when the snow melts, the ground floods into shallow pools; by late summer it dries out again, the water table dropping clean below the roots. That wet-then-dry rhythm is the whole secret — it's what lets these big hardwoods drive their roots down deep. This is a drowned-river woodland of swamp white oak and pin oak — with red oak and hickory and ash mixed in, a couple of them rare enough that the state keeps a worried eye on them — and some of these trunks have stood here around three hundred years, since before there was a United States, still rooted in the middle of Detroit. An arborist who studied this stand aged one fallen oak at nearly two centuries, and reckoned others older still. Short, flat, family-easy trails thread right through it. Let me clear up one common mix-up while you're here: this is not the old Belle Isle Zoo, the Safariland that closed decades ago. That was a different place, long gone. And you may have heard about the island's famous deer. Those were fallow deer, an introduced species, not the native whitetail — the herd grew to some hundreds, fell sick, and the last of them were moved off the island years back, so don't go looking for a deer to feed. What's here now is the living, daily forest, free and open. So take the short stroll: this is about as wild as the island gets. Then we turn for home. From here the loop straightens onto the north shore, the Detroit mainland rising across the water, and the bridge waiting at the far end, with one last story to tell before it.
