please let me know how I can reach Bergen from Sandnes?
my email is : firstname.lastname@example.org
First of all, you shouldn't spread your email out here, just because someone love to use it for spam!
From Sandnes you can take the local bus to Stavanger, where you can take a express boat to Bergen.
Or, you may take the train to Stavanger and the bus to Bergen (recommended): …nor-way.no/nbeiis/…
As stated above the train is the easiest way to get from Sandnes to Stavanger. There are frequent departures during the day.
