Is it possible to book one of the Fjord Tours from Bergen but return to Oslo at the end of the tour? We are flying to Bergen and then will make our way to Stockholm to attend a conference. Would like to spend a couple of days in Bergen, then do a fjord tour, a few days in Oslo, and then on to Stockholm. I don't see any scheduled tours that aren't round trips. Thanks much.
When you say "scheduled tours," I'm not sure what you mean. Where are you looking, and what sort of tour do you want?
It is easy to go from Bergen one-way to Oslo on the Norway in a Nutshell tour, but that's not a scheduled or organized tour as such; it is a package of transportation (and possibly lodging) options. You can book it as a package at the NiN website (https://www.norwaynutshell.com), or you can book all the arrangements independently.
If you're looking for something more like an organized, guided tour, I don't really know what the options are for that, but I think it's easy and pleasant to do this on your own.
