I want to know how much a public transportation ticket valid one year costs for Hamburg (Germany) and surrounding towns.
Old question but it specifically mentions other cities and not the regional transport so if that is too close range, there also is the Bahncard 100 which allows free use of virtually all long-distance trains throughout all of germany including the so called Regionalbahn (the R's on above plan or the black lines on this: http://www.hvv.de/pdf/produktplaene/hvv_produktplan_schnellbahnplan_usar.pdf). The Bahncard 100 currently is currently 4090€ per year but again, works in all of germany.
If you are looking for a cheaper option, there are CC-cards for Hamburg that work all day except 6-9am and 4-6pm on workdays. In that case, Großraum is 48.50€ and the whole HVV area is 80,40€ per month.
