Living in Sion: Housing, Language and First Steps

Sion is the capital of the canton of Valais, in the Rhône valley, with vineyard terraces on the slopes and two hilltop castles you can see from almost anywhere in town. If you are researching living in Sion, this page is for you: it assumes you have never been here and are planning from abroad. We go through the place, the language, housing, schools, getting around and the first steps after you land.

A quick note on how this works. Relocation Swiss is a matching service. We do not search for homes or file paperwork ourselves. Based on your request, we connect you with a relocation company that fits your situation. You can send that request at the bottom of the page.

The town at a glance

Sion is a small, calm cantonal capital rather than a big city. It has an old town with narrow streets, the two castle hills (Valère and Tourbillon), and vineyards that start almost at the edge of the center. Behind it, the Alps rise on both sides of the valley.

The official population figure for 2025 is 37,844 permanent residents (Federal Statistical Office, FSO). Of these, 11,696 are foreign nationals, or 30.9% (FSO, STATPOP 2025). So you will not be the only newcomer. Roughly one resident in three holds a foreign passport.

Here is what that tends to mean in practice:

Daily life is quiet and walkable, with a regional rhythm: markets, wine events, and weekends in the mountains.
It is a government town. The cantonal administration is based here, which is handy when you need an official office.
Smaller towns around the valley, such as Sierre and Martigny, and mountain resorts nearby, are all part of the same regional life. Many families look at several of these before choosing.

Language: what you will hear

Valais is officially bilingual in French and German (Swiss Confederation, Presence Switzerland). Official documents can come in either language depending on where you are in the canton. The statistics office does not publish a dominant language for the town itself, so we will not give you a percentage. Many newcomers find that everyday life in Sion runs mostly in French, with German never far away in the canton.

What you can do from home:

Start basic French lessons before you leave. Even simple greetings and form vocabulary help at the town hall and at the school gate.
Keep English for the practical stuff at first. Many people in services speak some English, but you should not count on it for official letters.
Save a translation app for the first months, especially for your tenancy contract and insurance paperwork.

Housing: renting in Sion and the Valais

Most newcomers rent first and look at buying later, if at all. Before you start, one honest limit: the statistics office has no rent figure for Sion alone. The numbers below are for the whole canton of Valais, so treat them as a rough guide, not a quote for the town.

For 2024, the average net rent in Valais across all sizes was CHF 1,227 per month (FSO). By number of rooms, the picture looks like this:

Average net rent in Valais by number of rooms, 2024

In more detail, a 3-room home averages CHF 1,260 per month and a 4-room home CHF 1,459 per month (FSO, Valais, 2024). These are averages across existing rentals, including long-running leases. A new listing, especially in a popular spot, can be priced differently.

On availability, the vacancy rate across Valais was 1.04% on June 1, 2026 (FSO). That is a canton figure, not a Sion figure, and we do not know the exact rate in the town. A low rate generally means you should expect competition and prepare your application in advance.

How the search works

In Switzerland, a landlord or a property manager (a régie in French) usually asks for a full rental file before offering a lease. That often includes proof of income, a copy of your ID or permit, and a debt-collection register extract. If you are arriving from abroad, some of these take time to arrange, so start early. Our rental file check shows what a typical file contains.

Things worth knowing before you search:

Rooms in Switzerland are counted differently from what you may be used to. A "3-room" home usually means two bedrooms plus a living room, with the kitchen and bathroom not counted.
Many leases ask for a deposit, held in a blocked account. The rules on its size are set by federal law, so ask the landlord what applies to your lease.
Viewings can be short and in French. Bring your documents, and consider asking a relocation specialist to help if you are not on site.

Schools and children

Public schooling in Valais is run by the canton and the commune, and in Sion it is mainly in French. For a child who does not speak French yet, that is a real adjustment, though young children often pick it up quickly with support.

We could not confirm a reliable list of international schools in the area, so we will not name any. If an English-language or bilingual school matters to your family, ask the canton and the commune about options before you sign a lease, because your address can decide which school your child attends. Our school choice tool helps you think through which school type might suit your child.

Here is an example, which is fictional: a couple from Singapore with two children aged 6 and 10 might choose to rent near the school they prefer, then plan an extra French course for the first term.

Getting around and travel

Sion is the kind of town where you can do a lot on foot or by bike. For longer trips, you will use trains and buses across the valley, and many people reach the rest of Switzerland by rail. We have not verified specific journey times, so check the national timetable for the connections you need and ask your relocation contact about your actual route.

If you need a car, remember that foreign driving licenses have their own rules in Switzerland. Ask the cantonal authority how this works for your country of origin.

Your permit and the cantonal office

Whether you need a permit, and which one, depends on your nationality, your reason for coming and your situation. The authorities decide; neither we nor your employer do. For people from the EU or EFTA the rules differ from those for people from other countries, so the first step is to check which group applies to you with the permit finder.

In Valais, the office for these questions is the Population and Migration Service (Service de la population et des migrations, SPM), listed by the State Secretariat for Migration (SEM). You can find it at the official SPM page. A specialist can look at your own case through the matching request.

Your first days in Sion

The order matters, and most of it you can prepare at home.

From packing to settling in

Register with the commune

In many Swiss communes you must report your arrival within 14 days (ch.ch). The deadline can vary by commune or canton, so ask the Sion town hall exactly what applies to you. Expect to bring your ID, your residence or work permit and proof of health insurance.

Health insurance and bank

Basic health insurance is compulsory for people living in Switzerland. Your commune will tell you the deadline that applies. Our relocation calendar puts these steps in a sensible order. A bank account usually comes next, since landlords and employers will ask for it.

Checklist for your first week
