The Brenta Dolomites Group runs from north to south for over 40 km, roughly from the bridge at Mostizzolo to Tione. It is bounded, going clockwise, by Lake Molveno and the Giudicarie Valley in the south, by the Rendena Valley up to the Campo Carlo Magno Pass in the west, by the Meledrio and Sole Valleys in the north and by the Non Valley in the east. In the Group a total of eight peaks exceed 3,00 metres (Cima Tosa, Cima Brenta, Crozzon di Brenta, Cima Ambiez, Cima Mandron, Torre di Brenta, etc.), while many others exceed 2,800 metres. The whole of the territory of the Brenta Group is part of the Brenta Adamello Nature Park.

After Lake Molveno, the largest lake in the Brenta Dolomites is Lake Tóvel, once famous for the reddish colour of its waters (a phenomenon that no longer occurs). Other lakes include Lake Valagola in the Agola Valley in the western sector of the Brenta, Lake Durigal near the Peller Refuge, Lake Salare near the former Malga Cavalli near the Nana Pass, and Lake Asbelz in the southern sector.

The main valleys and penetration points going clockwise from the south are: Algone Valley, Manez Valley, Flanginech Valley, Agola Valley, Brenta Valley, Vallesinella Valley,  Campo Carlo Magno Pass, Gelada di Campiglio Valley, Vento Valley, Cornai Valley, Cavai Valley, Mezol Valley, Tovel Valley, Madris Valley, Gelada di Tuenno Valley, Giare Valley, Arza Valley, Cadino Valley, Goslada Valley, Sporeggio Valley, Seghe Valley, Perse Valley, Ceda Valley, Ambiez Valley and Jon valley.
The main towns and villages within the boundary of the Brenta Group are, from the south-west and going clockwise: Stenico, Preore,  Ragoli, Giustino, Pinzolo, Madonna di Campiglio, Dimaro, Malé, Cles, Tuenno, Sporminore, Spormaggiore, Cavedago, Andalo, Molveno and San Lorenzo in Banale.

The main rivers are: in the west the River Sarca which collects the waters of all the rivers and torrents that flow down from the western part of the Brenta (Bondai, Ambiez, Rio dei Molini, Rio d'Algone, Rio Valagola, Sarca del Brenta); still in the west and after the Campo Carlo Magno Pass is the Torrente Meledrio, a tributary of the River Noce into which all the water courses of the north-eastern slopes of the Brenta flow.

Long before the first Alpine refuges were built, the main sign that humans were using the valleys were the shepherd’s huts (or malga in Italian); today some are still used by farmers grazing animals in the surrounding meadows, others have been converted into bivouacs or bars and others still have fallen into ruin.
