Ussassai - Niala

There is a wide variety of rock and grades, sport and multipitch. All on high quality grey to orange limestone.
Irtzioni has seen an increased influx of climbers because of its long endurance lines and excellent camping spot near the crag. In days of Mistral winds, this sector is completely sheltered.

The climbing sectors around Niala have started around the year 2002 with Mocci e Oviglia. Later Ruben Beckers, Frances Collins, Klaas Willems and PAolo Stagnoli have bolted the sector Irtzioni in collaboration with the town hall of Ussassai.
