Best Beaches In Sardinia

I've never been to Sardinia, but whenever I look at the pictures I imagine how great it would be to move there :D I always wanted to live near the seaside, the "sardinians" are so lucky :D

So, looking at the link, I love how the Cala Luna beach looks like, so deserted and peaceful... Perfect for a quiet day at the beach... if such a thing really exists :D
