St Moritz sits at 1,822 metres in the Upper Engadine, in a high valley that is unusual even by Swiss standards: it is one of the driest and sunniest places in the Alps, with around 322 days of sunshine a year, and it is also genuinely cold, with January averaging around minus 10°C at night and regularly colder. The combination catches people out. The sun is strong enough to burn badly at that altitude on snow, and the air is dry enough that the cold does not feel like the damp cold of a lowland winter until you stop moving.

The other thing about St Moritz is its reputation, which is half true and worth being precise about. This is where alpine winter tourism was invented, in 1864, and it has hosted two Winter Olympics. It is expensive, and in the high season between Christmas and February there is a visible fur and jewellery crowd. It is also a working Swiss valley with public buses, a spectacular railway, mountain huts and some of the best high altitude hiking in Europe in summer, when prices fall and the place relaxes considerably.
What Makes St Moritz Different to Pack For
Dry cold at altitude
Winter runs from around minus 15°C at night to a few degrees above freezing on a sunny afternoon, and the valley regularly records some of the coldest temperatures in Switzerland. Summer is mild, 8°C to 20°C, and nights stay cool even in July. Rain is low year round.
A merino wool base layer for women is the foundation of any winter here, worn under a fleece mid layer and an insulated shell. Dry cold is manageable with proper layering and miserable without it, and cotton next to the skin is the mistake that makes a ski day cold.
The sun is the hidden hazard
UV at 1,800 metres is far stronger than at sea level and snow reflects most of it straight back up, which is why people burn on the underside of the chin and nose. High factor sunscreen, reapplied, proper category three or four sunglasses or goggles, and lip balm with sun protection. This is not optional in February.
The dress question, honestly
Nobody will turn you away from a mountain restaurant or a bus for being in ski gear. The formality is concentrated in a handful of hotel bars and restaurants in the evening in high season, where a jacket or a dress is the norm, and in the events like the White Turf horse races on the frozen lake. One smart outfit covers it, and plenty of visitors never need it.
Recommended Tours and Experiences
The St Moritz Packing List
Winter layers
Merino base layer top and bottom, fleece or light down mid layer, insulated and waterproof outer, warm hat, proper gloves or mittens, a neck gaiter and thick socks. Mittens beat gloves below minus 10°C. A second pair of gloves, because the first will get wet.
Two merino tops cover a week: one for the mountain, one dry for the evening. The odour resistance matters when you are sweating under layers all day.
Footwear
Winter boots with real grip and insulation for the village, which is steep, and which the town grits but does not clear to bare pavement. Ski boots are hired or brought depending on how often you ski. In summer, waterproof hiking shoes for the trails, which are rocky, and boots if you intend anything above the tree line.
The village itself is built on a slope with lifts and escalators connecting levels, which is worth knowing when choosing accommodation with luggage.
Sun protection, again
Listed above and repeated because it is the thing people underpack. Add a wide brim sun hat for summer hiking, where the alpine sun on an exposed ridge is fierce.
For summer
Layers rather than warm clothing: mornings near freezing, afternoons pleasant, and afternoon thunderstorms that build fast over the peaks. A packable rain jacket, a daypack and water. Swimming in the Engadine lakes is possible and bracing, around 15°C at best.
What to Wear at Key Sites
The mountains
Corviglia above the town, Corvatsch across the valley at 3,303 metres, and Diavolezza towards the Bernina are the main areas, linked by lift and bus rather than all being skiable end to end. Corvatsch has a long night skiing run and Diavolezza the view of the Bernina glaciers.
Practically: the top stations are considerably colder and windier than the village, often by ten degrees plus windchill, and they close in storm. Check conditions before going up and note the last descent time.
The frozen lake
Lake St Moritz freezes solid enough to carry horse races, polo and a temporary village on it from roughly January to early March. Walking across it is normal and the marked routes are checked.
Practically: it is completely exposed with nothing to break the wind, and it is the coldest place in the valley. Full winter kit, and stay on the marked paths, since the ice is not uniform and the marking exists for a reason.
The Bernina Express
The Rhaetian Railway over the Bernina Pass is a UNESCO World Heritage line and runs year round from St Moritz down to Tirano in Italy, climbing to 2,253 metres without a rack, through the Brusio spiral viaduct. It is the single best thing to do here that does not require skis.
Practically: carry a passport, since the line crosses into Italy. The panoramic carriages have sealed windows, so the regional service is better for photographs. It is warm inside and cold at the pass if you get off.
Summer hiking and the Engadine valley
The valley has hundreds of kilometres of marked trails, the lakes at Sils and Silvaplana, the Muottas Muragl ridge walk, and the Swiss National Park an hour east, which is the strictest protected area in the Alps where you may not leave the paths at all. Sils Maria has the Nietzsche house.
What Not to Bring
Leave cotton base layers, which is the packing error that makes a cold day genuinely unpleasant. Leave the idea that you need formal clothing for the whole trip, since one outfit covers the handful of places that expect it.
Leave shopping for forgotten items until you arrive, because Swiss resort prices for basics are memorable. Leave the assumption that sunny means warm at 1,800 metres.
Essential Resources for Women in St Moritz
Emergency numbers in Switzerland: police 117, ambulance 144, fire 118, and 112 also works. Mountain rescue is Rega on 1414, which is the number that matters here and the one to have saved before going up. All operators handle English.
Tourist support: Switzerland has no separate tourist police; the cantonal police in Graubunden handle everything and speak English. St Moritz tourist information is in the centre and holds the avalanche bulletin and lift status.
US Embassy in Bern: Sulgeneckstrasse 19, CH-3007 Bern, telephone +41 31 357 70 11, at ch.usembassy.gov. St Moritz is around four hours from Bern, which makes it one of the more remote corners of Switzerland for consular purposes. Enrol in the Smart Traveler Enrollment Program at step.state.gov before you travel.
Main hospital or clinic: the Spital Oberengadin in Samedan, a few kilometres away, is the valley hospital and is well equipped for exactly the injuries this area produces, with a 24 hour emergency department. Swiss healthcare is excellent and very expensive, there is no free treatment for visitors, and a helicopter rescue off a mountain runs into thousands, so travel insurance that explicitly covers winter sports and mountain rescue is essential rather than advisable.

Solo women safety assessment: St Moritz is about as safe as travel gets for a woman alone. Switzerland has very low crime, the Engadine is a wealthy and orderly valley, public transport is reliable and safe late, and a woman eating alone, skiing alone or hiking alone attracts no attention whatsoever. Street harassment is essentially absent. Every meaningful risk here is the mountain. In winter, that means avalanche danger off piste, which is real and kills people in Graubunden most seasons, so read the SLF bulletin, stay on marked pistes unless you have a guide and the equipment, and never ski off piste alone. Cold injury is the second: at minus 15°C with windchill on an exposed lift, frostbite on cheeks and fingers happens faster than people expect, and the dry air disguises how cold it is. Third is simply the last lift, since being on the wrong side of a mountain when the lifts stop is a serious situation rather than an inconvenience; check the times and start descending earlier than feels necessary. In summer, the equivalents are afternoon thunderstorms that build very fast, exposed ridges with no shelter, and paths with steep drops. Tell someone your route. The social side is worth one honest note: the high season bar scene around the grand hotels is affluent and can be pushy in an ordinary way, and drinks cost what they cost; nothing about it is unsafe, but a single glass of wine at the wrong hotel bar will surprise you. Carry your Rega number.
