Oslo Seilforening is a sailing club in Oslo whose base at Lille Herbern turns into a summer camp site during the school holidays. The club runs its Seilglede summer camp for children aged 7–12 and a separate Seilcamp for teenagers aged 13–17, both held in the first two and last two weeks of the summer break, alongside its year-round courses and training for young sailors. Weeks are led by coaches educated through the Norwegian Sailing Federation who sail and race themselves, and the club supplies the whole fleet — Optimist dinghies, RS Feva and RS Quest, windsurf boards, kayaks and towable tubes — so families arrive with nothing more than a packed lunch.
