Last month, I went on a mini road trip in Sardinia. If you want to know more about it, watch the video below:
We started from Cagliari, then drove to Alghero, then Stintino, back to Alghero, then Olbia (around Porto Cervo), then back to Cagliari and drove to Chia.
If you need more details, please let me know in the comments.
