The insider read
Lake Michigan dunes meet boreal bog within a mile. Sites 1-50 are tent-only (walk-in); 51-66 are RV-friendly. Closest legal camp to the new NP (designated 2019). South Shore train station 0.5 mi walk for car-free Chicago day-trip.

Every fact above is sourced from the managing agency's canonical page. Cross-check fee, season, and size limit before you depend on them.
Match the campground's size limit and hookup level to a vehicle category, then plan the rest of the trip.
Keep exploring
Near Nashville
StateInsider tip · Largest IN state park (16,000 acres). October peak leaf-peep books a year out — Nashville town packed Sat/Sun. Buffalo Ridge loop has the full hookups; Taylor Ridge has the privacy.
Near Marshall
StateInsider tip · Sandstone canyons rare for the Midwest. Trail 3 (Falls Canyon) requires wading in summer — wear sandals not boots. The Turkey Run Inn restaurant fried chicken is a hundred-year tradition.
Near Heltonville
USFSInsider tip · Monroe Lake — largest reservoir in Indiana. Hardin Ridge has the best lake view + Monroe boat ramp. The 'Whippoorwill' loop nearest the swim beach books first weekends.
Near Madison
StateInsider tip · 4 waterfalls along a 425-ft canyon — best flow late winter through spring. Sites in the 'Reservation' loop have the canyon-rim overlook. Madison town below is the historic 1850s riverboat district.
Your next step
Dunewood Campground (Indiana Dunes NP) takes rigs up to 35 ft, so what you arrive in decides whether the loop works at all. If you don't own one, the same trip runs on a motorhome rented in Indiana.
Nothing in Indiana is bookable today. Dated requests are what we take to owners, so give us the window you actually want — you get one email the day a rig covers it, and nothing else.
