Our favourite. We always go to the left where all the kite surfers are. You can can park the car on the most left parking and walk through the dunes to the beach.
It's a windy place, good for kiting. The sand is a bit coarsely and the water gets deep quite fast. But the dunes are just beautiful. On a clear day one can see corsica.

Spiagge Liscia Ruja is a beautiful beach, clear water, white sand and very clean. Since very close to cala di volpe this beach gets very crowded in the summer months (july and august) but in the of-season it's beautiful. A perfect beach with kids. We always drive to the very end of the bay, we like it best there.

So far Rena Majore is one of my favourite beaches in Northern Sardinia. It's a long beach with shallow and very turquoise water.
You have a lovely view on the open sea and the horizon. There's several beaches next to each other. We always go to the one closest to Santa Theresa. The more left one is more crowded but also very nice.
On the very right side of the beach there is a rocky shore great for snorkelling. We found 2 octopuses there.
Sometimes the dunes behind the beach are a bit dirty.
