Trains go from Bergen to Oslo, and a large part of the railway line goes through Hordaland. Among the stations are Dale, Voss and Finse, the highest station on the line. Local trains stopping at all stations are fairly frequent between Bergen and Voss and have open seating. Express trains don't stop at all stations, and seats there are frequently reserved, especially on Fridays and Sundays you may have trouble getting a seat. Trains are operated by the Norwegian National Rail Company NSB.
Passenger boats along the coast are an option, especially if you are visiting islands such as Stord. Even if you are travelling by road, chances are good that you will come to a stretch of water where there is no bridge, and you will need a car ferry to get across. The frequency varies considerably, car ferries are part of the Norwegian road infrastructure and are usually, but not always, fairly frequent. The fast passenger boats are not so frequent. Most boats are operated by the transportation company Tide and schedules can be obtained from their website (unfortunately, only in Norwegian) passenger boat schedules, ferry schedules.
Where trains or boat are not available you will need to travel by road, whether this is in a car or by bus. Norwegian roads are frequently ridiculed for poor standards. The standard varies from location to location. If you need a bus, there are some express busses operated by NORWAY Bus express, and more local busses operated by Tide. Outside of Bergen and its vicinity you will probably find busses to be rather infrequent, but the network does cover most areas.
