Penultimate stage of the uphill trail to Caravius: having reached a spring (after a 4-hour walk), the old cart road continues under the woods with a series of 5 hairpin bends, until arriving, on a slight descent towards the East, at Arcu Sa Gruxitta (996 m, 0.45 hours – 4.45 total), where you can rest comfortably.
From Arcu de Sa Mossa you can admire a magnificent panorama: from left to right, the granite ridge of M. Genna Spina (971 m), Rocca Steria (1009 m), M. Is Caravius (1112 m) and then, after Arcu Sa Gruxitta (996 m), the peaks of Sa Gruxitta and Sa Mirra and the Tiriccu (1104 m) and Nieddu mountains, as well as the wooded and verdant valleys below and the Cuile Giriadroxiu sheepfold.
