Planning Tools

The planner's reference.

Seasons, packing, payments, connectivity, booking windows, the useful apps. Everything you set up before the trip, so you can stop thinking about it once you arrive.

Seasons at a glance

Switzerland runs four cleanly defined tourist seasons. Each rewards a different traveller. The colour markers below indicate when a season is at its peak, when it is good but quieter, and when access is limited.

March — soft ski April — meltwater & cities May — wildflowers June — long days July — full alpine August — peak crowds September — golden trails October — larch turn November — shoulder, limited cars December — ski opens, markets January — deep winter February — sunniest snow

The shoulder rule

The honest tip from inside the country: late September to mid-October is the most rewarding window for a Switzerland visit. Crowds thin, prices on alpine resort hotels drop by 30%, the larch forests turn gold, and almost every cable car is still running. November is the only month to avoid unless you specifically want pre-season Christmas markets — most mountain infrastructure shuts for maintenance and the lakes get foggy.

Packing

A Switzerland packing list looks different from the rest of Europe because altitude is always in play. Even a one-day excursion to Jungfraujoch puts you at −5°C in July. Build your layers around versatility.

Footwear — trail runners with grip if you plan walks; full hiking boots only for multi-day routes above 2 000 m.
Outer layer — wind- and water-resistant shell, even in summer.
Mid layer — fleece or thin down. Mountains are cold; cities are not.
Sunglasses + SPF 50 — snow and high-altitude UV reflection are brutal.
Adapter — Type J (Swiss three-pin). EU plugs fit but lock awkwardly; bring an adapter.
Reusable water bottle — almost every Swiss city fountain delivers drinking water.

Currency and payments

Switzerland uses the Swiss franc (CHF), not the euro. Euros are accepted in border-region cafés and tourist shops but at unfavourable rates with CHF change. Cards work everywhere — Visa and Mastercard universally, American Express in larger venues. Contactless and Apple/Google Pay are ubiquitous. Cash is needed only for small mountain huts and rural cable-car kiosks.

Withdraw locally, do not pre-buy Foreign-exchange counters at the airport take a 7–9% spread. Use any Swiss ATM (PostFinance, UBS, Raiffeisen) and your home-bank card with a no-fee debit account. Wise and Revolut work flawlessly in Switzerland and avoid the dynamic-conversion trap at point of sale — always pick "charge in CHF" when prompted.

Connectivity

Switzerland is not in the EU, so EU roaming does not apply. UK and US travellers should expect home-operator roaming charges unless they have an explicit Switzerland-included plan (most US T-Mobile international plans cover it; UK plans usually do not). An eSIM from Salt or Swisscom costs around 30 CHF for 10 GB / 30 days and activates in minutes. Public Wi-Fi at SBB stations and every major museum is free and decent.

Booking windows

The country runs on punctuality, including in how far ahead you should book.

Booking	Open at	Why
Trains (domestic)	60 days ahead	Saver fares appear, cheapest tier sells first
Trains (international)	92 days ahead	TGV Lyria / Eurocity tiered pricing
Jungfraujoch	30 days ahead	Slot-based since 2023; sells out in August
Glacier Express seats	90 days ahead	Mandatory seat reservation
Mountain hut beds (SAC)	2–3 months ahead	Limited capacity, summer weekends fill fast
Hotels (resort areas)	4–6 months ahead	Christmas / Easter weeks book early
Hotels (cities)	2 weeks ahead	Usually plenty of inventory

Useful apps

SBB Mobile — official rail app, also for boats and city transit. Tickets, real-time timetables, Half Fare Card storage.
MeteoSwiss — federal weather. The only forecast that gets alpine weather right.
SchweizMobil — official hiking, cycling and skiing route maps with downloadable offline tiles.
Magic Pass — if your trip is winter-heavy: bundles 30+ small ski areas for 419 CHF.
SwissTopo — topographic maps; the only thing that holds up above 2 500 m.

Tipping & etiquette

Service charge is included by law. Round up to the next franc in cafés, leave 5–10% in restaurants only if service was warm. Tipping is appreciated but never expected. Punctuality is its own currency: be early for trains, on time for restaurants, and within five minutes of arranged meetings. Anything later is read as inconsiderate.

Plan Switzerland once, with margin, and the country runs itself. Plan it loose, and the country runs you over with its timetable.

Last verified: May 2026. The booking windows shift slightly with seasonal product launches; SBB publishes a fresh schedule each December and June.
