The water flows quickly in this treacherous channel. Vessels need to creep through narrow, winding passages in order to reach the island’s landing stage. And then suddenly it opens up and Bassholmen landing stage lies in front of you along with Föreningen Allmogebåtar’s museum and the old, red boatyard buildings. The society works idealistically to preserve old Nordic boat types. On Bassholmen day, which is always the 2nd Saturday in July, the society exhibits its craft, the boats gliding proudly past in the narrow passage. The museum is open from middle June to middle August. Overnight accommodation is also available here at the youth hostel housed in the former farm house.

Another noteworthy event, in the spring, is the ‘release of the horses’ when the stallions are let out here to do their summer work. This event provides the perfect opportunity for that first, spring, countryside picnic.

Bassholmen's story can be traced back to the Middle Ages, when it was an estate owned by Dragmark’s closter.
Bohuslän through the ages has had periods when the herring have been plentiful. This seemed to occur about every 70 years. During the sill period that fell in the middle of the 18th century, the herring salting and train-oil factory were started up on Bassholmen. When the herring went their way again, the train-oil factory was transformed to a boatyard. At the beginning of the 20th century the herring returned and a guano factory was started in the same place. Herring oil and herring flour were produced from the fish. However, this herring period was short lived; the factory failed and was reborn as a mechanical workshop, which was operative until the end of the 1950s.
Today Bassholmen is a nature reserve and popular tourist attraction.
