Today's drive takes you very close to the base of Osorno volcano, which dominates the skyline. If you travel direct this is a three-hour drive heading due south - a journey of around 200km. The route includes a 28km stretch along the shores of sapphire-blue Lago Llanquihue, following a road running between the towering, conical giant of snow-stifled volcano Osorno which dominates the southern lake district and the waters of this huge lake, around which are studded many of the region’s most important towns (Puerto Varas, Frutillar and Puerto Octay) summer resorts and water sports.
However, again it's worth taking the day to do it, allowing for a stop for lunch at Puerto Octay, and meandering slowly along the lakeshore towards Ensenada. If the sun's out and the sky is blue there will be superb views across the lake towards Calbuco volcano on the other side. Reaching Ensenada, you branch off towards Petrohué where you’ll be spending the night.
Petrohué, on the western shores of Lake Todos Los Santos, consists of little more than a post office a few boats and a couple of hotels but it is a good place from which to stretch your legs for a countryside walk, such as the two-hour trail up to the lookout point on the top of Cerro Picada, with expansive views.
