Nice ride to do both on road bike and gravel, roads with little traffic with asphalt in good condition. You pass through small villages after being able to fill your water bottles or make a short stop at the bar to refresh yourself

Very ancient and little known funerary structure from the Nuragic era (around 1250-1350 BC) consisting of a large entrance portal and an internal dry-walled room. It was discovered, untouched, in the 1960s. The access is hidden by the vegetation: it is necessary to travel briefly on a dirt road for 100 meters (leaving the Provincial 29 from Sennori towards Tergu, on the left shortly after the Dettori estates), and descend between the mastic scrub towards the vineyard below, on the right side. . The monument, although not marked, has a very remarkable and very suggestive archaeological importance.

Always assess the specific route details and your family's fitness level before heading out.
