The Bardolino zone is situated in the Veneto sector of the morainic amphitheatre of Lake Garda, formed by the glaciers that shaped the Garda basin. It includes the whole of the communes of Garda, Bardolino, Affi, Cavaion Veronese, Pastrengo, Lazise and Castelnuovo del Garda, and part of those of Torri del Benaco, Costermano sul Garda, Caprino Veronese, Rivoli Veronese, Bussolengo, Sona, Peschiera del Garda, Sommacampagna and Valeggio sul Mincio.
To the south, its border runs along the outermost morainic ridge and rises up it towards the north until it enters the valley of the River Adige just to the west of Bussolengo. From there it follows the course of the river as far as Canale di Rivoli Veronese and then traverses the high rocky escarpment of the valley, bearing westwards at the hamlet of Vezzane in Caprino Veronese. It then remains in the midst of the slopes of Mount Baldo and descends towards the lake at Torri del Benaco, before proceeding south along the shore of the lake.
The morainic landscape in the central/southern sector of the region is characterized by a dense series of elongated hills, with modest differences in altitude, occasionally separated by small, narrow valleys or gravelly plains. The undulations become more significant in the northern sector, in which one also finds very sizeable rocky outcrops, such as the Rocca di Garda and Mount Moscal.
Theses have been added to by the deposits left by the tongue of ice that descended along the valley of the Adige and which created the morainic amphitheatre of Rivoli Veronese, lying between Affi and Caprino Veronese. In this zone a broad fluvio-glacial plain separates the two morainic apparatuses, as well as delimiting the initial slopes of Mount Baldo.
