Tomm Murstad Sjøleir
Høyerholmen, Oslofjorden
An overnight summer camp on the island of Høyerholmen in the Oslofjord, run since 1960. Children and teens aged 9 to 15 fill their days with sailing, motorboating, water skiing, wakeboarding and other water activities, and their evenings with camp life. Demand is highest in weeks 1, 2, 7 and 8, so be quick when registration opens: for the 2027 season it opens on Wednesday 4 November at 6pm.
The camp runs eight weeks with capacity for 68 participants a week. Participants stay in rooms in the main house with three to five beds, or in four-person cabins. Activities range from sailing, motorboating, water skiing, wakeboarding and kneeboarding to a water park, trampolines, rowing, beach volleyball and water-safety training.
Dates, prices and registration change from break to break and are listed with the organiser. Registration often opens early in the year, and some programmes fill up early.
