If you get lost
STOP protocol: the most important rule
- STOP — do not keep walking without direction
- THINK — what do you know? what can you see?
- OBSERVE — recall your last known position
- PLAN — call for help and stay put if you have signal
Most mountain tragedies happen when someone who is lost keeps walking and moves further from the trail. Staying put dramatically increases the chances of being found.
Before you leave: register your itinerary at the park ranger station. In El Chaltén, Aconcagua and Volcán Lanín this is mandatory. In Nahuel Huapi National Park (Bariloche) the Trekking Registry is mandatory and free: complete it online at nahuelhuapi.gov.ar or barilochetrekking.com. Leave a copy of your plan with someone you trust outside the park.

Extreme cold and hypothermia
Recognising it in time can save a life
- Intense shivering → first warning sign
- Confusion, clumsiness, slurred speech → moderate hypothermia
- No shivering, unconscious → critical emergency, call 105
- Insulate from ground and wind BEFORE warming
The cold damp air in Patagonia is deceptive: at 10°C with wind and rain the risk of hypothermia is real. The key is a layering system:
• Base layer (wicks moisture): merino wool or synthetic, never cotton
• Mid layer (insulates): fleece or down
• Outer layer (protects): waterproof windshell
What NOT to do: do not rub frozen extremities, do not give alcohol, do not immerse in hot water. Warm the core (torso, armpits, groin) first.
Improvised shelter
The priority is to insulate yourself from ground and wind
- Find natural windbreak: rocks, embankment, dense forest
- Insulate from the ground first (loses more heat than air)
- Emergency bivvy/space blanket: always in your pack
- Two people together generate more heat
In Argentine national parks cutting live vegetation to build shelters is prohibited. Use only fallen material.
Camping inside parks is only permitted at designated campsites (serviced campgrounds or registered technical campsites). Camping outside authorised sites can result in fines and harms the ecosystem.
Basic emergency gear: bivvy bag or aluminised emergency blanket, sleeping bag rated for the minimum expected temperature plus 5°C margin, insulating sleeping mat.
In national parks: do not cut live vegetation. Camp only at authorised sites.
The 10 essentials
What you must never leave behind
- 1. Navigation: map, compass, GPS (with spare batteries)
- 2. Illumination: headlamp + spare batteries
- 3. Sun and wind: SPF 50+ sunscreen, sunglasses, buff
- 4. First aid: basic kit + ibuprofen + antidiarrheal
- 5. Knife / multi-tool
- 6. Fire: lighter + waterproof matches
- 7. Shelter: aluminised emergency blanket
- 8. Extra food: enough for 1 additional day
- 9. Water: minimum 2L + purification tablets or filter
- 10. Communication: power bank, SPOT or PLB for remote areas
For Patagonia: add specific wind protection (windshell), warm layers even when leaving in good weather, and consider water weight (in Patagonia you can use a filter; in the Puna water may contain arsenic — use purification tablets).
For high-altitude areas (Aconcagua, Lanín): high-mountain goggles, crampons and ice axe are mandatory. Consult with your guide or the ranger station about required technical gear.
No signal
Preparation is the best connectivity
- Download offline maps before you leave (Maps.me, Wikiloc, OsmAnd)
- Share your route plan with someone you trust
- Agree on a check-in time (if no signal before X time, raise the alarm)
- For remote expeditions: consider a SPOT tracker or PLB (emergency beacon)
Coverage by region: Buenos Aires and Córdoba hills have decent coverage. Bariloche and Nahuel Huapi lake area have intermittent signal. El Chaltén, Fitz Roy and parts of the Northwest have extended no-signal zones. Aconcagua and the upper Lanín zone: no cell coverage.
VHF or satellite radio: for multi-day expeditions in remote areas, a two-way radio or satellite communicator (Garmin InReach, SPOT) is the difference between a story and a tragedy.
Navigation and orientation
How to navigate without GPS
- At noon the sun points NORTH in the southern hemisphere
- Use your watch: point 12 at the sun → the bisector between 12 and the hour hand points north
- Southern Cross: the longest axis points to the south celestial pole
- Mosses grow thicker on the south side (wetter and shadier)
Reading a topo map: contour lines close together = steep terrain; spread apart = flat terrain. Rivers and streams always flow downhill toward valleys. In Patagonia the strong winds come mainly from the west.
Basic compass: the red needle points to magnetic north (in Argentina magnetic declination is low, between 5° and 10° in most areas; it can be ignored for basic navigation).
No compass or GPS: follow a stream or river downhill. In the vast majority of Argentine parks they will lead you to inhabited areas or roads.
Exhaustion, dehydration and altitude
When to stop and how to act
- Golden rule: hydrate before you feel thirsty (every 20 minutes)
- Dark urine = dehydration; drink water NOW
- Altitude sickness: headache, nausea, dizziness → DESCEND, do not continue up
- Extreme fatigue: most accidents happen on the descent
Altitude sickness (soroche): affects from approximately 2500m above sea level. Mild symptoms: headache, insomnia, nausea. The only effective cure is descent. For Aconcagua and the NOA/Puna region (above 3500m): plan acclimatisation days, do not gain more than 300–400m of camp altitude per day.
Heat stroke (in the NOA and at low altitude in summer): red dry skin, high body temperature, confusion. Medical emergency. Cool with water and move to shade.
Emergency nutrition
What to carry and how to ration
- Always carry supplies for 1 extra day beyond your plan
- Energy priority: carbohydrates + fats (nuts, chocolate, cereals)
- Avoid food that requires a lot of water to prepare
- In extreme cold: eat more (the body burns more calories to stay warm)
Ideal emergency foods: nuts, peanuts, dark chocolate, energy bars, rice cakes, lightweight freeze-dried meals. Avoid heavy cans for trekking.
Cooking fire: in national parks fire is only permitted in designated fire pits. Outside those areas fire can cause devastating wildfires. Always carry a gas camp stove.
On hunting and fishing: hunting is prohibited in all Argentine national parks. Fishing with a permit is allowed in some parks (e.g. Nahuel Huapi, Lanín). Ask the ranger station. Do not rely on hunting or foraging as an emergency plan.
Fire only in designated pits. Hunting is prohibited in all national parks.
Safest areas of Argentina in a global catastrophe
Nuclear war, tech collapse or pandemic: what the evidence says
- Nowhere is 100% safe: distance, water, food and community are what protect you
- Argentina has no nuclear weapons and lies in the Southern Hemisphere, far from the most likely targets
- Nuclear-winter studies place Argentina among the countries best able to keep producing food
- Within the country: far from big cities, ports, nuclear plants, military bases and AI mega data centres, with its own water
What the science says: the study by Xia and colleagues (Nature Food, 2022) modelled world food production after several nuclear-war scenarios. Southern Hemisphere countries with large farming capacity —Argentina and Australia among them— are among the least affected, because they are far from the likely targets and produce far more food than they consume.
How to judge an area within Argentina:
• Distance from likely targets: Greater Buenos Aires, Rosario, Córdoba, Mendoza, Bahía Blanca (port and Puerto Belgrano naval base), major ports and refineries.
• Distance from the nuclear power plants: Atucha I and II (Lima, Buenos Aires) and Embalse (Córdoba).
• Distance from AI mega data centres: they are critical infrastructure that could be targeted in a conflict or cyberattack, and they compete with residents for power and water (details below).
• Wind: in Patagonia and much of the country the prevailing winds blow from the west. Being west of a possible target reduces exposure to fallout; being east of it increases it.
• Own resources: fresh water (rivers, lakes, snowmelt), farmland, firewood and low population density.
Areas that tend to meet most of these criteria: the Andean valleys of northern Patagonia (Comarca Andina: El Bolsón, Lago Puelo and El Hoyo; Esquel and Trevelin; San Martín de los Andes and Junín de los Andes). They have snowmelt water, local farming, favourable winds and few inhabitants. Downsides: harsh winters, reliance on roads for fuel, and few major hospitals.
AI mega data centres in Argentina (public projects as of September 2026; none is operating yet):
• OpenAI + Sur Energy ("Stargate Argentina"): up to 500 MW and about USD 25 billion in Patagonia. They signed a letter of intent in October 2025, but there is still no confirmed site or final investment decision.
• Pampa Energía: studying a centre of up to 500 MW in Neuquén, next to its Loma de la Lata plant and powered by Vaca Muerta gas. The areas under evaluation are in the Confluencia department, near the Limay River (Senillosa and Arroyito were mentioned, unconfirmed). It would also supply 30 MW to a data centre in the Bahía Blanca free-trade zone.
• Green Capital (Poland): 300 MW in a first phase, expandable to 3,000 MW, south of Trelew (Chubut), with its own wind and solar farms. Still seeking investors.
• Amazon Web Services ("Project Tango"): bought land in the Bahía Blanca–Coronel Rosales free-trade zone in 2019, but the project has been on hold since 2020.
The government is pushing a "Super RIGI" incentive bill through Congress to attract more projects, so this list will change. Sources: Reuters, BNamericas, Infobae and La Nación.
The best protection is preparation: an emergency kit, a family plan and knowing your area are worth more than moving far away.
This is a general risk analysis, not a guarantee. In a real emergency, always follow Civil Protection (SINAGIR) and the Nuclear Regulatory Authority (ARN).
Nuclear or radiological emergency
Get inside, stay inside, stay tuned
- GET INSIDE the sturdiest building nearby: a basement or the middle of the building
- STAY INSIDE for at least 24 hours: fallout radiation drops fast in the first hours
- STAY TUNED on a battery AM/FM radio: follow Civil Protection and the ARN
- If you were outside: remove your outer clothing and wash with soap and water (no conditioner)
The 7-10 rule: every time elapsed time multiplies by 7, fallout radiation drops about tenfold. After 7 hours it is near 10%; after 2 days, near 1%. That is why the first hours are the most critical and why sheltering works.
Best shelters: basements, underground car parks and the middle of concrete buildings. The more mass (earth, concrete, brick) between you and the outside, the better. A car does not protect you.
If you are trekking: find a deep cave, a stone hut or a slope that shields you from the windward side. Cover your mouth and nose. Prefer bottled or spring water; avoid rainwater, puddles or snow that fell after the event.
Potassium iodide tablets: they only protect the thyroid and only help when the authorities tell you to take them. Do not take them on your own.
If you live near Atucha (Lima, Buenos Aires) or Embalse (Córdoba), learn the local emergency plan: the plants have defined protection zones and evacuation routes.
In a real emergency, instructions from Civil Protection and the ARN take priority over this guide.
Tech blackout: cyberattacks and AI
No internet, no GPS, no banks: what to do
- 72-hour kit: water (about 4 L per person per day), food, torch, battery radio and first-aid kit
- Cash in small notes: with systems down there are no cards or transfers
- Offline and paper maps + compass: GPS can fail or be jammed
- An agreed meeting point with your family, in case phones are down
A large-scale cyberattack, with or without artificial intelligence, targets critical infrastructure: the power grid, telecoms, banks, water and fuel. The real risk is not a robot: it is spending days without power, signal or digital money.
Practical preparation:
• Download offline maps of your area and your routes in advance (Sliabh keeps them on your phone) and carry a paper copy.
• Keep a battery or hand-crank AM/FM radio: it is the most reliable way to get official information.
• Keep power banks or a solar charger topped up, and store cooking fuel (gas canister or stove).
• Write important numbers on paper: 911 (emergencies), 107 (medical emergencies), 100 (fire brigade), 103 (Civil Protection), 105 (environmental emergencies).
• Be wary of alarming or supposedly official messages on social media: AI makes it easy to fake voices and videos. Confirm by radio or through official channels.
Jammed GPS: if your position jumps or does not match the terrain, switch to map and compass (see the Navigation guide).
Pandemic or biological emergency
Distance, hygiene and isolation: what works
- Follow the Ministry of Health and local authorities, not forwarded chat messages
- A well-fitted N95 mask + ventilation greatly reduce respiratory infection
- Wash your hands with soap and water for 20 seconds, or use 70% alcohol gel
- Two-week supply: food, water and your usual medication
In a biological emergency (pandemic, outbreak or incident), low population density lowers the risk: rural and mountain areas get infected later and more slowly. But they are also farther from hospitals. If you have a chronic condition, being near a health centre may matter more than isolation.
If you plan to isolate in a rural or mountain area: bring several weeks of medication and a full first-aid kit, and tell the authorities when you arrive in a small community; many restrict access during outbreaks.
Water: if in doubt about its source, boil it for at least 1 minute (3 minutes above 2000 m).
A real risk today in Andean Patagonia is hantavirus, carried by the long-tailed pygmy rice rat. Air out closed huts and cabins for at least 30 minutes before going in, never dry-sweep (wet the floor with water and bleach first) and sleep in a closed tent.
With severe symptoms (high fever with difficulty breathing), call 107 or 911.
