Marstrand
Marstrand is a small island town north of Gothenburg, characterized by its maritime history and Carlsten Fortress. You reach the car-free island of Marstrandsön from Koön via a ferry that runs 24/7 and takes only about two minutes. The Carlsten Fortress, once a defensive fortification and prison, towers over the town and offers expansive views of the archipelago. Well-preserved wooden houses line the streets of the old town, and the harbour is a renowned sailing centre. In the 18th century, Marstrand was a free port, and in the 19th century, it became a popular seaside resort. Outside the peak season in July, it is significantly quieter. An approximately 5 km circular path leads around the island, past cliffs and swimming spots.
