Norway Nutshell Direction
 

Curious which direction I should be going on the Norway in a Nutshell tour as a roundtrip from Bergen.

Bergen - Voss - Gudvangen - Flåm - Myrdal - Bergen
or
Bergen - Myrdal - Flåm - Gudvangen - Voss - Bergen

I guess what my question boils down to is: which direction offers the best experience on the bus hairpin turns and the Flam railway? Should we go down on the bus and up on the railway or vice versa?

We did the railway first and loved the views of the fjord as we approached coming down into town. Took the bus back, by then, we were tired and it didn't seem nearly as impressive. YMMV

I would choose depending on how long you have to wait in Myrdal (shortest time possible as it's just a railway station in the mountains) and how long you have in Flåm (probably a good idea to have a little time here in order to get food and refreshments).
You get the same views whichever direction.

Dyoll, very helpful thank you!
