If you're into hiking, explore the Gorropu Gorge. It's one of Europe’s deepest canyons and offers breathtaking views and challenging treks.

You should also visit the little-known Nuragic complexes, especially the Nuraghe Losa. These are unique megalithic edifices built around 1500 BC.

That sounds amazing! How about local foods or drinks that are off the beaten path?

Definitely try the local pecorino cheese and carasau bread. Also, if you're there in autumn, don’t miss the local grape harvest festivals.

For a real treat, find a 'sagra' (food festival). It’s where locals celebrate their food culture, and you can sample various dishes not typically found in restaurants.

If you enjoy diving, the underwater caves near Alghero are a must. The Nereo Cave is particularly spectacular.

This all sounds wonderful. Any tips for interacting with locals and respecting Sardinian cultural etiquette?

Sardinians are very welcoming but also appreciate respect for their traditions. Learn a few words in Italian or even Sardinian to show respect.

Also, when visiting religious sites, make sure to dress modestly as a sign of respect.
