From the Fuhlsbüttel lock, the bed of the Alster no longer has its original character, but rather resembles a canal. The natural course was straightened and the banks bordered. Together with other (also canalised) tributaries (Isebek, Goldbek, Eilbek), canals and ponds, a network of waterways is formed that runs through several districts of Hambugr. Of course, the plots on the water are popular with the people of Hamburg, so that you can visit many villas from the water. Due to the regulation of the flow of the Alster lakes, there are no currents in the entire area. In addition, the area is hardly used by motor boats (you need a separate permit, which is only granted very reluctantly) so that the only noticeable shipping traffic comes from the Alster excursion boats (Alster steamers). When the weather is good, the area is popular with water sports enthusiasts of all kinds. Sailors cavort on the Outer Alster, canoeists, rowers, lovers in pedal boats and recently also stand up paddlers ride in the canals. Several boat rentals offer their services and various clubs have their boathouses in this area.
