Sardinia Beach Guide

One of the biggest questions I had before going to Sardinia was to understand which were the beaches I should not miss once I was there. I look for information on the web, I bought a guide and asked friends but I couldn't really make up my mind since it was my first time on the island. Now that I have gone, enjoyed and come back I though it could be useful and nice to make a little map on Google, pinning all the beaches I visited, giving a brief description and attaching few pictures for each of them, so should you go there, or just enjoy a bit with your imagination, you can have a better idea on what to visit.
This is mainly Costa Smeralda, I hope to pin up more soon...!

Said that all the places I have seen are absolutely stunning, I mention 5 beaches that are a must if you are around the area:

1. Gemelle - Capriccioli
2. Spiaggia del Principe - Romazzino
   
3. Capo Coda Cavallo
4. Baia Trinita - Maddalena Island
5. Spiaggia del Cavaliere - Budelli Island
