Korpo-Korppoo is situated in the middle of the archipelago. Only one tenth of the surface area is land, the rest is water. The largest island is Kyrkland, another central island is Norrskata. On Korpo you can stay in a holiday village or on a farm. A water taxi will take you into the Archipelago National Park, and in the summer boat trips are arranged to Jurmo and Utö in the outer islands.

See the grey stone church on Korpo that originates in the 1200's, the wooden church on Norrskata and the chapels on Aspö and Jurmo. Visit the district museum or the weather radar, and get a good view of the national park from the interesting look out tower on Rumar with its Solateria and coffeeshop. The light house on Utö is the oldest in Finland. Jurmo is at the end of the Salpauselkä ridge that runs across the whole of Southern Finland finishing in the Baltic. The island of Jurmo is known for its flatfish.
