Rock River Canyon Wilderness
Upper Peninsula, central · Hiawatha National Forest (USFS)
Two deep sandstone canyons with waterfalls and the Eben Ice Caves nearby, rugged and lightly visited once the day crowd goes home.

Works for hammock, tent. Measured dark skies, a real one for stargazing.
Hanging a hammock?
Hammocks are fine in Michigan state parks. There's no rule against them. The rule is about the tree: use wide, tree-friendly straps, no nails or wire, and don't tear the bark. The state sets no strap or tree-size requirement, so when in doubt, ask the park. We'll point you at sites that likely have trees worth hanging from, but we can't see the trunks, so eyeball it on arrival.
The rules
No permit or fee; primitive dispersed camping. No designated infrastructure. Standard Hiawatha wilderness Leave No Trace rules apply.
~30 min SW of Munising.
