We are now planning to rent a car for a day to see Diemtigen (ancestral home area) and the cheese/chocolate factories in Gruyeres and Broc. Google maps shows a road over what appears to be mountains that is slightly faster than driving back through Bern. I'm just wondering if anyone can tell me whether this is an easily drivable road or if we should go back through Bern. It would be fun to see some new country and it is probably beautiful, especially if it is a mountainous area. But, it also could be a slow drive if it is a bunch of switch backs with cliffs off to one side.
Thanks for any insight!
