All of those visitors who want to get to know the real Hamburg, sooner or later do have to enjoy a boat tour. This is why, the Discovery Ticket includes both a city tour by bus as well as a Lake Alster cruise. A day pass for the hop-on hop-off bus enables you to stop at 20 different stops all day long. Please bear in mind that you have to redeem your bus ticket on the bus prior to taking the Lake Alster cruise.
