Port of Lirquén, Multipurpose port terminal in Concepción Bay, Chile.

The Port of Lirquén is a multipurpose terminal in Concepción Bay, Penco, Biobío Region, with two piers offering six berths and drafts up to 50.8 feet. Its 415,000 square metres of storage yards, warehouses, sheds, workshops and administration buildings handle cellulose, sawn timber, logs, panels, bulk, containers and break bulk.

In 1953 Carbonífera Lirquén lengthened its wharf so ships could berth directly, ending coal loading via barges; coal, phosphorite and bagged sugar were shipped. The mine soon closed but the port kept working: wheat and fertiliser were unloaded in 1958 and sawn-wood exports began under the Tome businessman Alejandro Quiero Avendaño. Wharf 1 was extended in 1984 to four ships, containers arrived in the 1990s, and Wharf 2 was built in 1995–1996.

The terminal supports regional development by connecting agricultural, forestry, and salmon industries from regions VII to X with international markets through maritime trade.

The port can accommodate vessels of substantial size and manages container, bulk, and breakbulk cargo operations. Visitors should be aware this is an active port facility with limited public access to operational areas.

The La Tosca yard was created by filling in the seabed, removing a hill of sterile material left by the old Lirquén coal mine. The port now covers 415,000 square metres of storage yards, warehouses, sheds, workshops and administration buildings.
