Being close to the sea makes Göteborg special. And nowhere is the sea so close as in the archipelago. Whether blue and tranquil or turbulent and restless, the sea is always a source of fascination. As are the cliffs, houses and boats. A trip out into Göteborg's archipelago is a magnificent experience whatever the season. Take the ferry from Saltholmen for the southern archipelago. Check out the Elfsborgs Fortress. This 17th century fortress is located at the mouth of the Göta River and has a fascinating history. The island boasts a café, dungeons and a period church. Why not take a guided boat tour, 30 minutes, out to the fortress island? It covers the inner and outer parts of the harbour, and a guide welcomes you to the island and talks about the captivating history of the fortress.
