Calais to Slovenia via Furka Pass

[nickoff]

I’m hoping to ride from Calais to Slovenia via the Furka Pass then onto Budapest in June on my little Enfield. Can anyone recommend a decent route to get to the Pass without too many toll roads. I realise toll roads are sometimes a necessity but would like to break the journey up a bit. I’ll be travelling with a couple of mates, sometimes camping other times stopping in hotels etc. Most of the route planners that I’ve looked at are telling me that to get to Obergoms, the start of the Pass, I have to take a train trip. Surely not?
Any recommendations gratefully received.
Nick.

Could the train be the Chunnel crossing?
In the past we have headed for Lausanne via Reims and Besancon and then on to the passes.

No it wouldn’t be the Channel crossing as I asked for a route from Calais to Obergoms.

We've taken the bike on the car train near Interlaken under the mountains
'The Lötschberg Tunnel Car Train is a service that transports cars through the Lötschberg Tunnel in Switzerland. The tunnel connects Kandersteg station and Goppenstein station, allowing drivers to travel between Interlaken and Zermatt without crossing the Alps. '

I did a similar route on my Innova 125 a few years ago.
Just be aware that if you ride motorways in Switzerland, and sometimes it’s hard not to, you will need a swiss vignette that costs I think chf40 for the year.
Sometimes routing on apps and Google changes cause passes are shut at the moment. Last year they didn’t open til quite late into June.
Enjoy

Route now sorted. The first 300 miles or so on the A6 auto route and then carry on to Brig mostly on the smaller “N” roads.
