Olbia and Nuraghe Riu Mulinu Loop

The full loop tour typically starts from Olbia. For those looking for a shorter, easier route to the Nuraghe, you can drive closer and park near a spring, from where it's only about a 24-minute walk to the site.

The trail features a varied terrain, including both paved and unpaved roads, as well as dedicated hiking paths. You'll walk through fragrant Mediterranean scrub and encounter granite rocks, especially near Punta Zapparottu. The ascent to Nuraghe Riu Mulinu involves a steep but gradual climb on a paved road through bushes.

The full loop tour is classified as a "hard hike" and requires very good fitness due to its distance (approximately 19.3 km) and elevation gain. However, there are easier options; you can drive a significant portion of the way to reduce climbing, or take a shorter, easy route from a parking area near a spring, which is suitable for all skill levels.

This route offers a blend of historical sites and stunning natural views. You'll pass by the Olbia City Hall, the ancient Gates of the nuraghe Rio Molinu, and the Roman Aqueduct of Cabu Abbas. The highlight is the Nuraghe Riu Mulinu itself, offering breathtaking panoramic views of the Gulf of Olbia and the island of Tavolara.
