Hike from the Valle di Bresimo to Lake Trenta

This hike to the Laghi Trenta at the border between Val d’Ultimo in South Tyrol and Valle di Bresimo in Trentino offers stunning views

Our summer hike in the Maddalene Group starts at the car park of Malga Bordolona di Sotto at 1,806 m a.s.l., 8 km from the village of Bresimo. Malga Bordolona is the only restaurant along this itinerary. Initially, we climb the slope to Malga Bordolona Alta (also known as Malga Bordolona di Sopra) along a comfortable forest path, before taking the more direct itinerary no. 136 at the third hairpin bend.

At Malga Bordolona Alta (2,084 m a.s.l.) start several hiking paths to the Valle di Bresimo, the Val di Rabbi and the Val d'Ultimo. We continue towards north to passo Alplahner and climb the sunny meadow slopes of the Valle del Vento (Tal des Windes). We enjoy a stunning view of the Dolomites on the horizon and the Valle di Bresimo below us before reaching the 2,424-metre high pass after one hour of walking. We are now in South Tyrol. In front of us lie the Laghi Trenta. The lago Trenta at 2,387 m a.s.l., the largest one of these lakes, delights us with stunning views of the left valley slope of the Val d'Ultimo. We take a break in nature and relax in a colourful landscape characterised by the deep-blue water of the lake and the brownish alpine pastures. We retrace our steps to return to the starting point.

If you would like to extend this hike you can continue to the Cima Trenta (Welscher Berg, 2,636 m a.s.l.), walk around it and proceed to the Passo di Val Clapa at 2,296 m a.s.l. and the two malghe Scalét before returning to the Valle di Bresimo. This alternative with minimal elevation gain can be completed within an hour.
