Yes it is a beautiful town and you are fortunate to have this heritage! Using the ferries we passed under several bridges, so ferries are not the only way to get to and from Stavanger... but must be used to navigate the fjords.

UPDATE: Since I first posted, some of the transportation schedule links have been dropped. Here are the directions for using the Kolumbus.no site to find ferry schedules for the Lysefjord / Lysebotn.

First, if you use the English link you will be directed to the seasonal tourist ferries. If you want the Express ferries (Hurtigbater), try using the regular site.

From the home page www.kolumbus.no find the heading for route schedule tables and maps 'Rutetabeller og kart'.
Select Boats 'Bat'.
From the drop-down menu select 'Hurtigbater'

'Rutekart' means route map - select 'Lysefjorden'
'Ruter i Ryfylke' are the timetables for the Ryfylke province - select 'Lysefjorden / Fisteroyene'

The days of the week are in short-form

Sunday sondag: son
Monday mandag: man
Tuesday tirsdag: tir
Wednesday onsdag: ons
Thursday torsdag: tor
Friday fredag: fre
Saturday lordag: lor

og means 'and'
Just guessing here but - the footnotes indicated by a or p refer to the ports of call and times being dependent on whether passengers and/or freight needs to land or be picked up at those locations.
