San Carlos de Bariloche sits on the southern shore of Lake Nahuel Huapi at about 770 meters, in the Argentine province of Río Negro, at the northern end of Patagonia. Behind it the Andes rise to 3,400 meters, and around it lies Argentina's oldest national park, created in 1934 and covering 7,000 square kilometres of lake, forest and peak.

The town was settled largely by Germans, Swiss and northern Italians in the late nineteenth and early twentieth centuries, which is why the civic centre is built in Alpine style, why there is a chocolate shop every thirty meters, and why it is sometimes called the Argentine Switzerland. It has around 135,000 people and an economy built entirely on two seasons.
That is the key to packing for it. Bariloche is two different destinations depending when you come: summer trekking and lakes from December to March, and the largest ski area in South America from June to September. The shoulder months are quiet, cheap and unreliable.
What both seasons share is wind. Patagonian wind is the defining condition of this region: persistent, strong, funnelled between the lakes and the peaks, and capable of turning a pleasant 15-degree afternoon into something that requires a shell. A windproof waterproof layer is not an optional item here in any season, and it is the single most common thing people under-pack.
What Makes Bariloche Different to Pack For
The wind, and why a shell is mandatory
The westerlies come off the Pacific, cross the Andes, and dump their moisture on the Chilean side before arriving here dry and fast. The result is a landscape that goes from temperate rainforest to near-steppe within fifty kilometres, and a town where the wind rarely stops.
Practically: any ridge, any lake shore, any chairlift, any viewpoint. The temperature reading is close to meaningless without accounting for it, and a fleece alone is not enough because wind moves straight through fleece. A windproof, waterproof shell is the item that makes every other layer work.
The weather changes within the hour
Four seasons in a day is a cliché that happens to be true at this latitude and altitude. Sun, wind, hail and sun again in the space of a morning on Cerro Catedral is ordinary. Pack for the range rather than the forecast, and always carry the shell even when you leave in sunshine.
Summer versus winter
December to March, summer: 20 to 26 degrees by day, 8 to 12 at night, long daylight until nine or ten, and the trekking season. The lakes are swimmable if you are brave, which is to say cold.
June to September, winter: minus 5 to 5 degrees, snow, and Cerro Catedral, the largest ski resort in South America with around 120 kilometres of pistes and lifts to 2,100 meters. July is Argentine school holidays and the town is full.
April, May, October, November: the shoulders. Cheap, quiet, beautiful, and with many trails closed or snowbound and the lifts shut. April and May bring the autumn colour of the native lenga beech, which is worth seeing.
Recommended Tours and Experiences
The Summer Packing List
Base layers
Two Roman Trail Women's Merino Wool Base Layers ($49-59) in long sleeve. The swing here is the reason: 24 degrees on a lakeside afternoon and 8 degrees on a ridge in the wind an hour later. Merino at 17.5 micron insulates when the wind picks up and moves moisture when you are climbing, and it keeps working when damp, which fleece and cotton do not. For a multi-day refugio trek it also stays wearable across several days, which matters when everything you own is on your back.
Mid layer
A Columbia Women's Fast Trek II Jacket ($65). Fleece for the summits, the evenings, and the boat crossings, which are colder than the shore.
The shell, which is the mandatory item
A Marmot Women's PreCip Eco Rain Jacket ($110). Windproof and waterproof, hooded, packable. This is the single most important thing on this list and the reason people who pack well enjoy Bariloche more than people who do not.
Add waterproof trousers if you are doing anything multi-day. Baleaf Women's Hiking Eco Pants ($38) cover the walking trouser requirement and shed light rain.
Footwear
Merrell Women's Moab 3 Waterproof Hiking Boot ($140), broken in. Nahuel Huapi trails are rock, root, scree and stream crossings, and the classic routes to Refugio Frey and Cerro Catedral involve real terrain rather than paths.
The Darn Tough Women's Hiker Micro Crew Merino Socks ($28), three pairs for a trekking trip.
Plus one comfortable town shoe, because Bariloche has a good restaurant and chocolate habit.
Sun, which is stronger than it feels
The ozone layer over southern South America is thinner than at comparable northern latitudes, and at 800 to 2,000 meters with snow or water reflecting, the UV is genuinely severe. High-factor sunscreen, reapplied. Sunglasses with real UV protection. A brimmed hat with a chin strap, because of the wind.
Organisation and everything else
The Eagle Creek Pack-It Cube Set ($59). Two litres of water capacity, although Patagonian stream water is generally excellent. A headlamp for refugio nights. Trekking poles for the descents. A swimsuit, because the lakes are beautiful, cold and worth it.
The Winter List
Cerro Catedral runs from roughly mid-June to early October depending on snow, with lifts to 2,100 meters and views across the lake from the top.
Base layers: the same two merino layers, and merino base layer bottoms rather than cotton leggings under ski trousers.
Mid layer: the fleece, or an insulated jacket for lift days when you are not generating heat.
Outer: a proper insulated ski jacket and waterproof trousers, which most visitors hire in town alongside skis, and which is usually the better decision than flying with them.
Extremities: insulated gloves or mittens with merino liners underneath, a merino beanie, and a neck gaiter you can pull over your face, because a chairlift in Patagonian wind at minus 5 is the coldest you will be on this trip.
Boots: waterproof insulated boots for the town, which is snowy, slushy and steep, and ski boots hired at the hill.
Goggles rather than sunglasses on the mountain, and the same severe sun protection, because snow reflection at altitude here burns faces badly.
Hire versus bring: ski and snowboard rental in Bariloche is inexpensive and the shops are good. Bring your own base layers, socks, gloves and goggles; hire the rest.
The Circuito Chico
The single best half day in Bariloche, and the thing to do if you only have one.
What it is: a 65-kilometre loop road west of town around the Llao Llao peninsula, between Lake Nahuel Huapi and Lake Moreno, through native forest with viewpoints over both.
How to do it: by hire car in two to three hours with stops, by organised tour, or by bicycle, which takes most of a day and is the best version if the wind is kind. Local buses 20 and 21 run the first part of it as far as Llao Llao, which makes a partial version possible without a car.
What to stop for: Cerro Campanario, a chairlift to a 1,050-meter summit that gives what is genuinely one of the great views in Argentina, over the lakes in every direction; the Llao Llao hotel and its chapel; Bahía López; the Punto Panorámico; and Colonia Suiza, a small Swiss settlement that runs a craft market and cooks curanto, a meal baked in a pit with hot stones, on Wednesdays and Sundays.
What to wear: layers and the shell. The Campanario summit is exposed and windy in every season, and considerably colder than the road below it.
The Other Trips Worth Making
Refugio Frey: the classic day hike, about 10 kilometres each way from the base of Cerro Catedral, ending at a stone hut beside a glacial lake surrounded by granite spires. Seven to nine hours return, real terrain, and the best walk within reach of town.
Cerro Tronador and Ventisquero Negro: a long day trip to a glacier that carries so much rock debris it is black. The access road is one-way by timed hours, so you go with a tour or plan around the schedule.
Cerro Catedral in summer: the lifts run for walkers and mountain bikers.
Villa La Angostura and the Seven Lakes Road, running north towards San Martín de los Andes, which is one of the great drives in South America.
El Bolsón, two hours south, a hippie-founded town with a craft market, good beer and raspberry farms.
Chocolate, in town, on Calle Mitre. This is a genuine local industry descended from the Italian and Swiss immigrants rather than a tourist confection, and the older houses are worth the stop.
What Not to Bring
A fleece as your outer layer. Wind goes straight through it. The shell is the point.
An umbrella. It will invert immediately.
Cotton hiking clothes. They stay wet, and at these temperatures wet is a problem rather than a discomfort.
Skis and boards unless you are particular. Hiring locally is cheap and good.
Only summer clothes for a summer trip. The nights are 8 degrees and the ridges are colder.
An expectation of reliable card payment. Argentina's currency situation means cash is still king in smaller places, and exchange rates vary between methods. Check the current position before you travel.
Essential Resources for Women in Bariloche
Emergency numbers in Argentina: 911 for a general emergency in most of the country, with 101 for police, 107 for ambulance and 100 for fire also in use. 103 is civil defence.
Mountain rescue: report an overdue or injured walker through Club Andino Bariloche, which coordinates mountain rescue in the region, or via the national park administration and the police. Registering your route with Club Andino before a multi-day trek is standard practice here and is the mechanism by which anyone would know to look for you. They also hold current trail and refugio conditions, which change with snow.
National park: Parque Nacional Nahuel Huapi has an administration office in town and charges an access fee for some sectors. Trail closures and fire restrictions are posted there.
Tourist police: Bariloche has a tourist-facing police presence in the civic centre in high season, and the provincial police handle everything else. Argentina has a national tourist assistance line on 0800 999 2838.
US consular services: the US Embassy in Buenos Aires covers Argentina; there is no consulate in Bariloche. Contact details and the after-hours emergency number are at ar.usembassy.gov.
Hospitals: Hospital Zonal Ramón Carrillo is the main public hospital in Bariloche with a 24-hour emergency department, and Sanatorio San Carlos is the main private option used by visitors. Both handle mountain trauma routinely. Argentine public hospitals treat emergencies regardless of nationality or insurance; private care requires payment or an insurance guarantee up front. Check that your travel insurance covers hiking and, in winter, skiing, which many policies exclude.
Official health authority: the Argentine Ministry of Health at argentina.gob.ar/salud.
Official tourism authority: argentina.travel nationally and barilocheturismo.gob.ar for the town, which publishes trail status and lift opening.
US State Department travel advisory for Argentina: current advisory level and detail.
UK FCDO travel advice for Argentina: entry requirements, safety and health guidance.
Solo women safety assessment: Bariloche is a comfortable and welcoming place for a woman travelling alone, with a large hostel and trekking culture that makes finding company for a hike straightforward if you want it. Violent crime is low and the town centre is busy in the evening. The real risks are the mountains: weather that changes within the hour, wind that turns a manageable ridge into a serious one, stream crossings that rise after rain, and trails where you may not see another person for hours. Register your route with Club Andino before anything multi-day, carry the shell even in sunshine, and turn back rather than pushing a summit in deteriorating weather. In town, ordinary care applies: the streets below the civic centre towards the lake are quieter late, use remises or apps rather than unmarked cars, and be aware that petty theft from hostel dorms and from cars at trailheads is the most common visitor complaint. On the road, the Seven Lakes route and the Tronador access are narrow, gravel in places and unbarriered, and Argentine drivers are fast.
Reading On
Bariloche is the easiest entry to Patagonia and the only place in South America that does both a serious ski season and a serious trekking one. The Argentina travel guide for women covers the country and Buenos Aires the arrival city, with the Chile travel guide for women and Santiago just across the Andes. The Bariloche travel guide for women goes deeper on the region, and anyone heading further south should read the Patagonia packing list for women, which covers the harder end of the same weather. For why merino handles a 16-degree swing plus wind better than a heavier fleece, the merino wool base layer guide explains the fibre, and the full collection is at Roman Trail women's merino base layers.
