The Maderanertal is an Alpine valley of the Canton of Uri in Central Switzerland. It is drained by the Chärstelenbach, a stream that is a right tributary of the Reuss at Amsteg . The highest mountain in the Maderanertal is the Oberalpstock with a height of 3,328 metres above sea level. Other important summits are the Schärhorn , the Clariden , the Düssi , the Gross Windgällen , the Gross Ruchen , Piz Giuv and the Bristen .

The Maderanertal include two large lateral valleys: the Etzlital and the Brunnital, drained by the Etzlibach and the Brunnibach respectively (both left tributaries). The upper valley is heavily glaciated, the largest glacier being the Hüfi Glacier .
