Patagonia
Patagonia covers the southern cone of South America across Chile and Argentina, roughly 1,000 kilometres from the Lake District near Bariloche to Cape Horn. The scale is the first thing to accept: it’s enormous, the infrastructure is thin, and the distances between key sites are large. The two main draws are Torres del Paine in Chile and the Perito Moreno Glacier in Argentina. Both are excellent. A well-planned ten to fourteen day trip covers both with some flexibility for weather delays, which are a genuine planning factor.
Torres del Paine
The granite towers rising nearly vertically from the surrounding steppe are one of the more dramatic mountain sights on earth. The W Trek covers the main highlights in four to five days: Mirador Las Torres at the tower bases, Valle del Francés with its hanging glaciers, and Grey Glacier at the western end. Refugios (mountain huts) along the route provide beds and meals, eliminating the need to carry camping equipment.
Book refugios through Fantástico Sur and Vertice Patagonia (the two main operators) four to six months ahead for the November through March high season. This is not an exaggeration; they sell out completely by June for the following summer. The park entrance fee is around USD 50. Fly into Punta Arenas, bus to Puerto Natales (the service town 120 km from the park entrance), and on from there.
The wind is the practical challenge at Torres del Paine. Gusts above 100 km/h are possible throughout the summer; a windproof outer layer is more important than insulation. You will use it every day.
Perito Moreno Glacier
The Perito Moreno is unusual among glaciers: it is actively advancing rather than retreating. It periodically dams the southern arm of Lago Argentino in Argentina, building pressure until the ice wall ruptures in a massive calving event. The glacier advance and calving happen regardless of whether you are there to see them; the viewing walkways at the glacier face are free with park admission and put you within a few hundred metres.
The glacier is accessible from El Calafate (about 80 km). Boat trips on the lake provide close-up views from water level. Ice hiking on the glacier surface costs around USD 100 to 200.
El Calafate is the service town; functional, decent restaurants, not much else. El Chaltén, 220 km north, is the gateway for Fitz Roy trekking and is more compact and specifically hiker-oriented.
Eating
Patagonian lamb (cordero) slow-roasted over an open fire is the regional speciality. Centolla (king crab) along the Chilean Pacific coast is outstanding; the restaurants in Puerto Natales are significantly better value than anything in Torres del Paine itself.
Practical Notes
Weather changes fast; plan for four seasons in a day. Peak season is November through March; shoulder months (October, April) have smaller crowds at the cost of more weather variability. Book everything at least four to six months ahead for the main season. Card payment is accepted in El Calafate and Puerto Natales; carry some cash for park fees and smaller stops on the road.
