The city of Puerto Madryn is in the north east of Chubut Province in the Patagonia region of Argentina on the shores of Gulfo Nuevo, a large, deep water bay of the Atlantic Ocean. It is an important centre for tourists visiting the natural attractions of the Península Valdés and the coast. A new shopping mall in the city centre has helped tourism significantly, making Puerto Madryn a more attractive place for both international and domestic tourists visiting Patagonia. It is twinned with Nefyn, a small town on the Llŷn Peninsula in North Wales, the result of its enduring link with Welsh culture since the Welsh settlement in Argentina.
