July 6, 2026, Summit Cross of Punta La Marmora

The Monti del Gennargentu form the highest mountain range in Sardinia and the "roof of the island". It is located in the heart of Barbagia. The rugged, rocky mountain world is home to Punta La Marmora (1,834 m), the highest peak in Sardinia, as well as historical Nuragic villages, and offers fantastic hiking opportunities.
