The Iller (ancient name Hilaria) is a river in Bavaria, Germany. It is a tributary of the Danube, 147.0km in length.
The source is located near Oberstorf in the Allg鋟 region of the Alps, close to the Austrian border. From there it runs northwards, passing the towns of Sonthofen, Immenstadt, and Kempten. Between Lautrach near Memmingen and Ulm it forms the border between the two German States Bavaria and Baden-W黵ttemberg for about 50 km. The river flows into the Danube in the city of [[Ulm|Neu Ulm].
A bicycle route follows the Iller, which is also a popular location for rafting and trekking.
The power of the river is used for the production of hydroelectricity via eight power stations with a total net capacity of 51 MW (1998).
A generation later, Iller is the one sitting behind the wheel of a Conservation Foundation truck as the person in charge of managing more than 8,700 acres of protected land on Nantucket.
Iller himself was four days shy of being a native Nantucketer when his parents moved to Bedford, N.H. on Sept. 4, 1973.
Iller said the biggest challenge is accepting that he can鈥檛 be everywhere at once.
