It is home to some of the worlds most beautiful beaches - great for sun worshippers.
In order to have access to the best of the beaches you will probably need to hire a car (mopeds are not so good on the bumpy tracks down to the beaches). Driving on the coastal roads gives great views over the yacht lined Costa Smeralda coastline.
You can get up close to the super yachts when they come in to Porto Cervo in the evening. For snorkeling take a trip around the archipelago Della Maddalena from Porto Palau.
The best of the beaches are Liscia Ruia, Cappriccioli and Romazzino.
You can pick up fantastic bargains from the beach traders who sell jewellery, clothes, CDs etc. But if you want to be as stylish as the rich tourists of Costa Smeralda you may go to Porto Cervo or Porto Rotondo for expensive clothing.
Most restaurants on the Costa Smerelda are overpriced. For authentic Sardinian cuisine try the campsite restaurants where all the locals go.
It can be quite difficult finding accommodation in the Costa Smeralda as the area is mainly serviced by Italian tour operators but some local operators provide detailed accommodation information online. If you don't have your own private yacht to stay on and can't afford the £300 per night prices of the exclusive hotels then you might want to hire a villa through a website. Alternatively you can hire bungalows at a number of the campsites on the coast.

You will find Costa Smeralda to be a very safe and friendly place for your vacation, just remember to follow some easy rules.
When you’re going to the beach, you need to bring sun block and possibly to find out what the UV rating is for that day. UV rays are calculated on a 1-15 scale. Higher numbers mean more intense rays and the sun in Sardinia is going to shine every single day.
Keep plenty of water on hand. It's very easy to become dehydrated when you're in the sun all day.
To avoid loss, it's always wise to leave any important documents (like your passport), your credit cards, and most of your money at your hotel.
