Öjberget in Sundom is a unique area of land for the flat Ostrobothnian coast. Öjberget is located next to the meteorite crater Söderfjärden and is part of the ancient crater rim.
On the untouched rocky ground of the crater rim grow centuries-old oaks. Many legends have emerged over the years around this area, including about the elusive Öjbergsringen, about the Öjbergstrollen and about the Bergakungen.
