This was our 4th visit and easily the worst ref cable car. It took me 50 minutes from centre of town to the cable car but it seemed much longer. Not helped by a group of Italian women both large and very loud who tried to push past everybody and blocked those coming from the cable car. Eventually they were stopped by others and some sort of normality was restored. I fell in with 4 Americans on their first visit who were not impressed.
Google Norwegian met Office very accurate and comprehensive info 3/4 days out also UK Met Office very accurate 4cast this may help u decide whether to do either/or in Bergen.
we have done both funicular and cable car in Bergen but always independent of ship tours. We have been lucky with weather in Bergen 5 visits only one rain and that last Nov for northern Lights on QM2. Both have been offered by Cunard in the past but in my opinion not worth spending on (unless lots of OBC). Judge the weather on the day.
