Principality of Asturias (Principado de Asturias) is a region in the north of Spain.
As Asturias is a province, it's divided in "Concejos"
Asturias has its own language, Asturian, although everyone you meet will speak Spanish.
Asturian (also called Bable, but this is a derogatory term) is a Romance language spoken in some parts of the provinces of Asturias and León in Spain, and in the area of Miranda de Douro in Portugal (where it is co-official and officially called Mirandese). In Asturias it is protected under the Autonomous Status legislation, and it is an optional language at schools. There was a diglossia conflict between Asturian and Spanish, which resulted in some scholars considering it a dialect. However, nowdays it is considered a separate language, direct dialect of Latin.
Much effort has been made since 1980 to protect and promote Asturian among the Asturian population. However, establishing the language as a co-official tongue is still awaited in most areas to better protect this minority romance language. The situation of Asturian in other parts of Spain is critical, with a large decline in the number of speakers in the last 100 years. The area of Miranda de Douro in Portugal has taken a further step in protecting this language, by making it co-official.

There are two main options to arrive in Asturias. The first is to fly directly from Madrid, Barcelona, Paris or London, which can be fairly cheap, depending on when you buy the ticket. Asturias airport  is located near Avilés, and is easily accessible by bus from the three main cities of Gijón, Oviedo and Avilés. If you're coming from London try easyjet.com, which flies direct to Asturias airport or Air Berlin which flies to Asturias via Palma de Mallorca. From other areas in Europe try ryanair.com, which flies into Santander, less than a three hour bus ride from Oviedo. All three of these airlines are low cost carriers. If you're coming via Madrid, buses also frequently run from the bus station, which is accessible by metro from the airport. Tickets cost from about 30 euros each way and can be pre-booked online though the web site of the coach company ALSA . ALSA is the company that operates the majority of the inter-city buses. The bus takes a little over 5 hours. Train is a third option when coming from Madrid. Prices are from 27 euros each way for the discounted 'Estrella' tariff which must be booked at least least 7 days in advance through the RENFE (Spanish state railways) website . This makes it slightly cheaper than the bus. Otherwise the train is a bit more expensive, from 45 euros. The train is definitely the scenic option though. Nowadays there's a 'fast' connexion: high speed until Valladolid. There are also direct bus lines departing from Brussels, Paris, etc. See eurolines.com (in partnership ALSA).
All Asturian cities are very walkable, as they're quite compact. If you need a way to get around, bus and taxi are the two best options. Taxi stands are all over the city, and charge a base fee of around 4 euros. Getting from one side of the city to the other costs about 8 euros. Buses are the most convenient, and cheapest form of travel. The run from early in the morning until 11pm. Urban buses are around 0.85 euros. Schedules are available at tourist offices and bus stops. To travel between cities, both train and bus are good. There are 2 train networks: Renfe (the national railways) and Feve (smaller trains). They sometimes share station but not always. Finding them won't be a problem, though, as they're always clearly shown on maps.
Make sure you visit the Picos de Europa National Park
Within the city, there are various museums, historical buildings, etc. Be sure to walk around the centro antiguo, that being the part of Oviedo that was once encircled by a stone wall. The Cathedral, convent, and parts of the wall itself are just a few things to see. The Parque San Francisco is one of the biggest parks in Oviedo, complete with gardens, paths, ponds, and pavos reales (peacocks). This is just off of Calle Uría, one of the main shopping areas down town. El Museo de Bellas Artes, in the plaza of the Cathedral, contains works of Asturian artists as well as Picasso and El Greco. To get away from the city, try a walk up to El Cristo, located on El Naranco, which is visible from nearly all parts of the city. On the way up are two pre-romanesque buildings. La Pista Finlandesa is another nice option for walks or runs, as it skirts the Naranco hill and has full views of the city. Also, keep an eye out for the numerous statues and sculptures in Oviedo.
Night life in Oviedo is great. Try the Calle Mon, located just off of the Cathedral's plaza, but remember that most Spaniards don't leave home before 12:00. If you're an early bird, head to the Calle Gascona, just north of the Cathedral, which is said to be home of the largest number of sidrerias in the world. Sidra is an alcoholic apple cider famous to Asturias, with its own tradition. Be sure to ask a server how to correctly drink the beverage, and don't miss the way they pour it. Another game that can be played in many of the Bars in Oviedo and other parts of Spain is Duro. It is a drinking game similar to that of quarters. They play it with a drink known as Calimocho, a combination of Coke, red wine, and current berry syrup. Ask a bartender and they will give you the necessary cups, etc.
But Asturias is not only Oviedo. Try visiting coasts cities like Gijon and Avilés, spend a morning in Tito Bustillo caves, or relax in one of the thousand beachs in the province.
Los Premios Principes de Asturias are awards given by the Prince of Spain, known as the prince of Asturias, to various people for various categories. Previous winners are Nelson Mandela, Al Gore, Bill Gates, and Oviedo's very own Formula One racer Fernando Alonso. These awards take place each fall, and are held in Oviedo.
Fabada. Beans stew made of white beans of typical asturian type, red sausage (chorizo), black pudding (morcilla) and bacon cutted in dices.
Cheese. There are more than a hundred of different types of cheese in Asturias. The more well known is Cabrales cheese. Cabrales cheese is produced only in the village of the same name and three villages of the Peñamellera Alta township, located on the northern spur of the Europa Peaks in eastern Asturias. This is certainly the most well-known Spanish blue cheese due to the manner in which goat farmers jealously guard its origin and authenticity; and one of the great blue cheeses of the world.
Tortilla de Patata is a must anywhere in Spain (translated as an omelet of potato and onion). Try this along with a variety of tapas (croquetes, patatas, jamon, etc) and you'll be happy. Also, many places have bocadillos de tortilla, which is basically just a tortilla de patata on a french type bread.
Cider. Made of local apples, like the Raxao and Xuanina types. The peculiar way it is served is called "escanciar", dropping the cider from the bottle hold with one hand above the head while the thin wide special glass is hold with the other hand under the hip level.
Calimocho, made of red wine, Coke, and current or blackberry syrup is delicious, and fun when used to play Duro (see above).
Crime is definitely not a big problem in Asturias. In the inner cities, as night life is huge, and even grandmothers pushing strollers can be seen at midnight, being out late isn't a big concern (I felt safe walking 30 minutes home alone at night, and I'm female). Of course it depends on the area and bags can be snatched every now and then, so take general precautions.
