Sass de Mura, Mountain peak in Belluno, Italy

Sass de Mura is a mountain peak in Belluno with steep rock faces and several climbing routes on its southwestern side. The summit sits at about 2,547 meters (8,356 feet) and offers different ascent options with varying difficulty levels.

The summit was first climbed in 1881 by Luigi Cesaletti with Mariano Bernardin and Demeter Diamantidi, via the south-east ridge now known as Via della Croce, starting from a rock arch. Between the wars, routes by Ettore Castiglioni and Gabriele Franceschini made it popular; after 1945 it was neglected until the 1970s, when all faces were systematically explored.

The normal route, the Via della Croce, starts from the top of a rock arch on the south-east ridge, the line taken by Luigi Cesaletti with Mariano Bernardin and Demeter Diamantidi in 1881. Between the wars Ettore Castiglioni and Gabriele Franceschini opened routes on the north and east faces; from the 1970s climbers such as Conz, Pierobon, Levis and De Bortoli added lines on all sides, and Aldo De Zordi, Pierangelo Verri and Lorenzo Massarotto later climbed free at up to VII+ on the Parete Piatta.

The usual route, the Via della Croce, starts from a rock arch and follows the south-east ridge to the summit. The mountain lies on the border of the Belluno and Trentino provinces, with the Veneto side inside Dolomiti Bellunesi National Park. June to September gives the most favourable weather; the climb is on rock and calls for rope and climbing experience.

The first ascent was made in 1881 by Luigi Cesaletti with Mariano Bernardin and Demeter Diamantidi, via the south-east ridge now called Via della Croce; it starts from the top of a rock arch. The Parete Piatta, a buttress jutting south-east, holds the Via diretta opened in 1973 by De Bortoli, Conz, Frare and Pierobon (450 m, later freed to VI+).
