San Carlos de Bariloche is the Argentine Lake District’s largest city and popular with both Argentinian and foreign tourist summer and winter.
It is located on the shore of the beautiful lake Lago Nahuel Huapi (the picture above) and surrounded by mountains. The city offers many shops (specially chocolate shops), hotels and restaurants. But the real attraction is outside the city: Park Nacional Nahuel Huapi. The park offers splendid hiking, rafting and skiing.
It’s a fun place to visit, but be prepared that its rather expensive (for Argentina).
