Åland (Finnish: Ahvenanmaa) is an autonomous area in the Baltic Sea, consisting of one main island and a surrounding archipelago. While legally a part of Finland, in practice the islands run their own affairs and are rather different from the mainland.
The Åland Islands (pronounced "Oh-lahnd") are a group of small islands officially belonging to Finland but awarded a wide degree of autonomy by a League of Nations decision in 1921 that settled a long-running dispute between Sweden and Finland. Still at the time when Åland was under Russian sovereignty, a treaty was concluded between Russia, France and the United Kingdom at the issue of the Crimean War, by virtue of which the islands were demilitarized. Finland assumed the same obligation upon achieving independence. Among other things, Ålanders have their own parliament, publish their own stamps, are exempt from military service and maintain a special tax status in the European Union.
The archipelago consists of around 80 inhabited islands plus around 6000 uninhabited islands, islets and rocks. The total population is only 26,530 (2004), 90% of which lives on the main island Åland (also known as Fasta (Mainland) Åland), which includes the capital Mariehamn.
The islands are monolingually Swedish, a point of some contention in otherwise bilingual (or, in practice, frequently Finnish monolingual) Finland. English is widely spoken and generally spoken better than Finnish.
Finns from outside Åland, who want to establish resident's rights, not only have to reside for a minimum period but also to exhibit proficiency in Swedish. Moreover, if the Finnish Parliament passes legislation relevant to Åland, they must inform the Åland Assembly in Swedish.
There are plenty of ferry connections between Åland and mainland Sweden and Finland. Primarily for tax reasons, ferries plying between Helsinki and Stockholm all stop off at Mariehamn or the nearby (30km east, approximately) jetty of Långnäs, making this the easiest and cheapest way to get in (although docking often happens at inconvenient times in the middle of the night - the Långnäs stops). Mariehamn also has a small airport that serves flights to mainland Finland and Sweden.
Mariehamn airport - the only airport on the islands. There are daily flights from Helsinki and Turku and international flights to/from Stockholm. The flight from Helsinki is less than an hour and the flight from Turku and Stockholm is only half an hour. Mariehamn airport is situated less than 3km north of Mariehamn.

Kastelholm. A castle located in the northern part is worth paying a visit. Mostly a ruin today, it was home to many Swedish kings who reigned the combined kingdom of Sweden and Finland from this place. There are guided tours, also in English.

Svartbröd, Blackbread, as the name implies the bread is almost black. It is round and quite flat but its most characteristic feature is the taste. The blackbread is sweet. The sweetness originates from the syrup that is added to the dough and from the manner in which the bread is baked in the oven.
Cheese from the local ÅCA dairy is of high quality. The Kastelholm cheese is particularly recommended, and works well with blackbread. Its roots can be traced back to the 16th century.
