That sounds like an epic hiking trip. Can you share more detail about the specific route and accommodation etc? Do you happen to have a write up anywhere? Cheers!

Likely the pilgrim's trail. Oslo to Trondheim is the most popular of St. Olav's Ways.

The eastern route includes a trip on Skibladner, a steamboat on the aforementioned Lake Mjøsa.

All of western Europe has really well developed pilgrim trails. I hiked the coastal one in Portugal a few years ago that leads into the main Spanish ones.
