Baltic Sea

From here the boat turns north through the skerries and the open Baltic, passing the inlet of Bråvik and the steel town of Oxelösund, to enter the long, narrow Himmerfjärd, which leads into the fjord-like Hallsfjärd and the 5km/3-mi-long Södertälje Canal (constructed 1806-19), linking Lake Mälar with the Baltic.
