Alleuze is located some 7 km due south of
Saint-Flour on the edge of the Planèze plateau. Access to the commune is by a number of minor roads including the D48 from
Lavastrie in the west changing to the D40 in the commune then passing north through a circuitous route in the heart of the commune to the village and continuing north-west to the hamlet of Barry before continuing north to
Saint-Flour. There is also the D116 from the village to the north-west. The eastern and north-eastern borders of the commune consist of the lake formed by the Barrage of Grandval which was formed from the
Truyère river. Apart from the village there are also the hamlets of Barry and Vedrines. Much of the commune is farmland but with considerable forests next to the lake and in the south. Numerous streams rise in the commune and flow eastwards to the Barrage of Grandval Lake. These include the
