Practical Information for visiting Patagonia

Coverage for mobile networks is good in the towns — Bariloche, El Calafate, Ushuaia, Puerto Madryn — with 4G, and absent across most of the steppe and the national parks.

Long stretches of Route 40 have no signal at all, sometimes for hours of driving, which matters for breakdowns.

Local SIMs from Personal, Claro or Movistar are cheap; buying one requires a passport and can be slow.

Wi-Fi is standard in hotels and hostels and often slow, since much of the region is served by limited backhaul.

Download offline maps and trail information before El Chalten and any driving. Tell someone your plans on the remote roads.

Patagonia is very safe from crime. The dangers are entirely environmental and they are real.

• The wind is the most underestimated hazard. It has blown walkers off ridges, capsizes kayaks, and makes river crossings and exposed sections genuinely dangerous. Check the forecast, which locals take seriously.
• Weather change: hypothermia is the leading cause of mountain deaths here, and it can be summer. Carry windproof and waterproof layers on any walk, however short it looks.
• Glaciers: never walk on ice without a guide and crampons. Calving faces throw ice and generate waves — stay behind the barriers, which exist because people have been killed.
• Driving: gravel roads, loose surfaces, long gaps between fuel, guanacos on the road, and crosswinds strong enough to push a vehicle.
• Fire in the parks; open fires are banned.
• Sun: extreme UV, especially on ice and snow.

Hospitals in Bariloche, Ushuaia, Comodoro Rivadavia and Puerto Madryn are adequate; El Calafate and El Chalten have small facilities and serious cases are flown out. Given the distances, insurance covering evacuation is genuinely important here.

Vaccinations: routine cover. There is no malaria, no yellow fever and few tropical concerns — Patagonia is medically straightforward.

Hypothermia and exposure are the realistic risks. The combination of wind, wet and 5°C is more dangerous than dry cold, and it occurs in summer.

Sun and wind burn: the UV index is very high and reflection off ice and water compounds it. High-factor sunscreen, sunglasses and lip protection are not optional on a glacier day.

Hantavirus is present in the Andean region, carried by a rodent; avoid disturbing rodent droppings and do not sleep in abandoned buildings.

Tap water is safe and excellent in most of the region.

In the national parks: open fires are absolutely prohibited, camping is only at designated sites, and everything must be carried out including toilet paper. The rangers enforce this and the reason is the fire history.

Mate: if a gourd is passed to you, drink it all and pass it back without comment. Saying gracias signals you have finished and want no more, which surprises visitors who have been politely refusing refills all afternoon without meaning to.

Estancias are private property and working farms; ask before entering, and close gates behind you.

Wildlife distances at Peninsula Valdes and the penguin colonies are set by law — stay on the marked paths and let the animals cross them.

Mapuche land: some communities restrict access; respect signage.

Meal times are Argentine — dinner from nine, later at weekends.

Emergency numbers: 911 in most of the region, or 107 for ambulance, 101 for police and 100 for fire.

Park rangers are the first line in Los Glaciares and Nahuel Huapi. Register your trek at the ranger station in El Chalten before setting out — it is free, quick, and it is what triggers a search if you do not come back.

Medical. Bariloche and Ushuaia have the best hospitals; from El Chalten or the steppe, evacuation takes hours and may need aircraft. Insurance covering it matters.

On the road: carry water, warm clothing and fuel margin, and tell someone your route. A breakdown on Route 40 can mean a long wait with no signal.

Weather: forecasts for El Chalten and the ice field are posted at the ranger station and are reliable. Wind speed matters more than temperature.

Consulates are in Buenos Aires, a long way away.
