Children over the age of 10 can travel alone. Children under the age of 10 must travel with a person who has reached the age of 16. However, we point out that the crew has many tasks in terms of traffic flow and safety. A system has not been established to take care of children traveling alone. This is important to think about if you are considering sending the child alone by ferry. If there are groups / school pupils / kindergartens, there must be one companion per. 6 children under 10 years, and one companion per. 10 children between 10 - 16 years.
