The Archipelago Sea (Finnish: Saaristomeri, Swedish: Skärgårdshavet) is a part of the Baltic Sea between the Gulf of Bothnia, the Gulf of Finland and the Sea of Åland, within Finnish territorial waters. By some definitions it contains the largest archipelago in the world by the number of islands, estimated at around 50,000, although many of the islands are very small and tightly clustered.
The larger islands are inhabited and connected by ferries and bridges. Åland, including the largest islands of the region, forms an autonomous region within Finland. The rest of the islands are part of the region of Southwest Finland. The Archipelago Sea is a significant tourist destination.
The Guardian's journalist Tristan Parker wrote an article praising the Turku Archipelago on July 29, 2021, mentioning that "nowhere has the gentle magic of the smaller islands – or their wildlife."[1][2]
