If the weather is good, you just have to stop and rest on the bench here! Take in the beautiful views across the water to Tallholmen, Finnholmen, and countless smaller skerries and islets.

Cool, simple campsite right by the water. The pitch must be paid for at "Utö Gästhamn" at the "Gruvbryggan" ferry terminal.
