Numerous sailboats pass through the Sote Canal in summer; fortunately, this bridge is rotatable, allowing even boats with tall masts to pass through. The spectacle can be easily observed from the picnic stop next to it.

A narrow footpath without railings leads from Hunnebostrand across the shallow bay to the island where the marina is located. Take care when taking photos; one wrong step backwards will result in a wet landing.

Here you have a beautiful view of the Sotekanalen and the picturesque rocks around it. The ships seem to be sailing almost across the meadow.
