Famous National Park routes

Please add famous roads from national parks around the world. I’m familiar with the US western parks, so I would recommend starting with the circumnavigation of Crater Lake in Oregon. Also great would be Going to the Sun road in Glacier National Park or Tioga Pass in Yosemite National Park.

That would be really cool! Yellowstone and the Redwoods would be cool! (I know we have the Zwifty remakes but and real replica would be cool!

In climb portal would be most likely.

I’d be OK with that, or perhaps another type of portal. Not all epic routes are climbs.

The main highway through Zion National Park is stunning.

An issue with many of these roads is there’s limited looping options.
