Hamburg is a large city and that is also why its local transport is very diverse. You can find here all kind of transport possibilities; from metros to buses, trains and water taxis. They even offer hop on – hop off buses for tourists. The bus has 27 stations where you can get to know all the major attractions in Hamburg. The tickets will cost you 17,50€/pp for 24 hours and can be bought online.
You can also rent a free city bike in Hamburg, but only for 30 minutes and according to pre-registration.
If you decide to explore Hamburg with buses, trains or ferries and if you will have more time to spend here than only 24 hours, I would recommend you to get yourself a HAMBURG CARD. It costs 9,50€/pp per day and it offers free transportation and generous discounts in some of the museums, restaurants, theater performances and even in some souvenir shops, what can make your Hamburg visit even better.
