Patagonia

Patagonia isn’t a country — it’s the far south of both Argentina and Chile, and almost any trip crosses between them. Happily both are visa-free for up to 90 days for US, UK, EU, Canadian and Australian visitors, and the old reciprocity entry fees have been abolished on both sides. Chile issues a PDI tourist card on arrival — keep it for exit.

The practical border fact is agriculture: crossings (such as between El Calafate and Puerto Natales) enforce strict controls — no fresh fruit, meat, dairy or seeds — and everyone disembarks the bus for immigration on both sides.

Plan the itinerary as a two-country loop — typically El Calafate/El Chaltén (Argentina) with Torres del Paine/Puerto Natales (Chile) — and allow time for the border crossings. Don’t carry fresh food across, keep your Chilean PDI card, and if hiring a car to cross, arrange the notarised cross-border permit in advance.

The Chilean side’s crown jewel is Torres del Paine — a national park of sheer granite towers, glacier-fed lakes and roaming guanacos, and one of the world’s great trekking destinations. The two classic routes are the "W" (four or five days of the headline valleys) and the full "O" circuit (a week or more, adding the wild back side).

The thing to understand early is that it’s a reservation system, not a wilderness free-for-all: every night needs a pre-booked refugio or campsite across three operators, and the good ones vanish within weeks of opening. Puerto Natales is the base town for logistics and gear.

If Torres del Paine is your goal, book the refugios/campsites 4–6 months ahead (bookings open ~September 1) — this is the single biggest planning task of a Patagonia trip, and leaving it late means no trek. Base in Puerto Natales for gear and transfers, and buy the separate park entry ticket online in advance.

The Argentine side centres on Los Glaciares National Park and two very different experiences. Perito Moreno, reached from El Calafate, is that rare thing — an accessible, advancing glacier you simply stand and watch, as house-sized blocks calve off its face into the lake, with boat trips and ice-walks on offer.

A few hours north, El Chaltén is the trekking capital, built at the foot of the spires of Fitz Roy and Cerro Torre. Its best day hikes — above all the climb to the Laguna de los Tres — start right from the village, are free and need no permit, the easy counterpoint to Torres del Paine’s booking maze.

Pair El Calafate (Perito Moreno) with El Chaltén (Fitz Roy) — they’re a ~3-hour bus apart and complement each other perfectly, one a glacier day-trip, the other free self-guided trekking. Chaltén’s weather is notoriously fickle, so give it buffer days to catch a clear Fitz Roy.

At the very bottom sits Ushuaia, the self-proclaimed "end of the world" on Tierra del Fuego — a scrappy, scenic port beneath snow peaks, with its own national park and Beagle Channel cruises. It’s also the main embarkation point for Antarctica, whose expedition ships cross the Drake Passage through the austral summer (November–March).

Far to the north, a different Patagonia begins: Bariloche and the Lake District, a more temperate land of alpine lakes, chocolate shops and winter skiing — a reminder of just how vast and varied this region is.

Patagonia’s wildlife is as grand as its scenery. Torres del Paine is now one of the world’s premier places to track wild pumas, and guanacos and condors are everywhere on the steppe. On the Atlantic coast (a separate northern leg), the Península Valdés delivers southern right whales, penguins, sea lions and orcas.

Underpinning it all is the Southern Patagonian Ice Field, the largest ice mass outside Antarctica, which feeds the region’s great glaciers — and the wind, a relentless, gusting force (often over 100 km/h) that defines hiking and driving here, especially in the summer peak.

Patagonia is huge and sparsely populated, so logistics are the trip. Most people fly into the key hubs — El Calafate (FTE) for the glaciers, Punta Arenas (PUQ) for Torres del Paine, Ushuaia (USH) for the far south — to skip the enormous drives.

On the ground, a good tourist bus network links the hubs, including the cross-border run between El Calafate and Puerto Natales. Hiring a car is possible (Argentina’s legendary Ruta 40 runs the Andes’ foot), but taking it across the border needs a notarised permit — many travellers simply bus across instead.

Patagonia runs on the austral summer (November–March), peaking December–February: long days (16+ hours of light in December), every trek and refugio open, and the warmest, most settled conditions — which is also when it’s windiest and busiest, and when prices peak.

The shoulders (October and April) are quieter, with less wind and autumn colour in April, though shorter days and some services winding down. Winter (May–September) largely closes the trekking world — Torres del Paine’s circuits shut — bar the Bariloche ski season up north.

Two currencies are in play — the Argentine peso and the Chilean peso — so change money as you cross. The big recent shift is on the Argentine side: the chaotic "blue" (parallel) dollar rate has essentially normalised under 2024–26 reforms, the gap down to a few percent, so cards and ATMs now give near-market rates and the old habit of hauling US-dollar cash for a better rate no longer pays (the peso remains volatile, so re-check).

Either way, Patagonia is expensive and remote by South American standards — remote logistics, imports and high demand push prices up — and supply is limited, so refugios, Antarctica cruises and peak-summer flights must be booked months ahead.

Treat early booking as the golden rule — Torres del Paine beds, summer flights and any Antarctica cruise fill up far in advance. Don’t bother stockpiling US-dollar cash for Argentina any more; cards and ATMs are fine now. And budget realistically: this is the Andes’ priciest, most logistically demanding corner.
