Sardinia

Well, George Clooney would tell you not to drive a scooter.

Just looked at Wikipedia which has quite a bit of interesting history. They have mining tours, boat tours, diving, historic tours and architectural tours with a lot of things dating from the Phoenicians, Romans, Spaniards. Since there is a large Tech and Power industry there now there is probably a lot of nice hotels and restaurants to keep people with money happy.

I spent 11 days driving around Sardinia (in a car) and loved it. The city of Cagliari has a beautiful Cathedral, the Castelo, Bastion of St. Remy and a wonderful archaeological Museum. Alghero is a great city in which to wander, visit the cathedral and its museum and take the boat ride to visit the spectacular Grotto de Nettuno. Head down to Oristano and see the area archeologica di Tharros on the Sinis Peninsula. About an hour SE of Oristano (at the midway point to Cagliari) is the largest Nuraghe site on the island with a guided tour in English and museum entry included in the admission price. There's also the La Maddelena Archipeligo north of Olbia and wineries north of Cagliari.

So, there's a lot to do. If you go to Cagliari, the best Sardinian food I had was at Sa Domu Sarda on Via Sassari. I stayed at the Hotel Flora a few steps away and it was a very nice, elegant hotel. In Oristano I stayed at an inexpensive but very nice B&B called Sa Domu et Crakeras and had a great seafood dinner at the restaurant recommend by my host. Trattoria Portixedda is a very short walk from the B&B.

How about looking at the official tourism site for the Region of Sardinia:

Also I posted a lot of replies on Sardinia in the past. Just use the search button using the key word “Sardinia” or “Sardegna” and many will show up.

Andrew, what do you think of Corsica?

Not sure what one means by “backward” but I wouldn’t consider Sardinia any more backward than the average Italian region.
They have everything that all other regions have: drinkable water, electricity, paved highways, restaurants, hotels (even some of the fanciest in the country), banks, ATMs, high speed hydrofoils, 3 international airports.
It’s not the most populous region, and being big, that means that some areas are largely rural and not densely inhabited, but other than that, it’s a very civilized place. Since it’s the playground of Europe’s rich and famous, some areas have better infrastructure than the mainland.
Florence can only dream to have an international airport as efficient and modern like Olbia on the Costa Smeralda.

Corsica is equally beautiful, more rugged, with more lush vegetation (Sardinia is overall drier).

Corsica is part of France, so the downside is that you pay French prices. That means almost twice as much as Sardinia for equivalent items (restaurants, hotels, etc.)
