Fjeldberg båthavn (Fredrikstad Motorbåtforening)

Fjeldberg båthavn is a marina on the outskirts of Fredrikstad, sitting along the western shore of the Glomma river estuary. You'll find fuel (petrol and diesel) available here, making it a handy base if you're ranging along the Oslofjord coast. It's a no-frills, working kind of place rather than a polished resort marina, but Fredrikstad's famous Old Town fortress — one of the best-preserved Baroque fortifications in Scandinavia — is just a short distance away.
