Tunnel of Trees — M-119, Michigan
27 miles. Tree canopy. Lake Michigan bluffs. Class B + small Class C only.
Michigan State Route M-119 between Harbor Springs and Cross Village runs 27 miles along Lake Michigan's bluff edge under a continuous tree canopy. The route is narrow — no shoulder, frequent tight curves, and a canopy that closes over the road in summer. The Federal Highway Administration designated it a National Scenic Byway. For RV travelers, the road is suitable for Class B campervans and small Class C motorhomes. Class A and large rigs do not belong.

Can a Class A motorhome drive Tunnel of Trees?
Not comfortably. M-119's lane width is below normal Michigan highway standard. Tree branches overhang the road. Class A motorhomes risk lane infringement on oncoming traffic and branch damage to AC units. The route works for Class B campervans (up to 22 ft) and small Class C motorhomes (up to 25 ft). Large rigs detour via US-31 around the south end of Little Traverse Bay.
- Class B + small Class C only
- 27 miles narrow with overhead canopy
- Class A detour: US-31 around south
- Open year-round

Why this route is iconic
The canopy closes over the road in summer creating a literal tunnel of green. In fall (mid-September through October), the same canopy turns yellow, orange, and red. The route is genuinely one of the prettiest two-lane roads in the Midwest.
Multiple roadside galleries, small restaurants, and Lake Michigan overlooks. Legs Inn at Cross Village is a destination restaurant and worth the planning.
For RV travelers, the practical approach is to camp at Petoskey State Park or Wilderness State Park and drive Tunnel of Trees as a day-trip in a tow vehicle if you have a large rig.
What Michigan tourism + Pure Michigan doesn't tell you
Pure Michigan markets the Tunnel of Trees prominently for fall color. The honest reality for RV travelers includes the vehicle-size constraint that the marketing doesn't surface.
The route is genuinely worth visiting if you have the right rig (Class B) or a tow vehicle. The full Lake Michigan circle tour using M-22, M-119, and US-31 is one of the great underdiscovered RV scenic drives.
