Switzerland's reputation for expense is deserved, which makes every percentage point on the exchange rate matter more. Buying travel money before you go from a commission-free provider such as Travel FX softens the famous Swiss prices at least a little.
Alpine huts, cable car snack bars, village bakeries and small ski schools appreciate francs, and coin-operated lockers and launderettes insist on them.
The Swiss like exact payment, so a mix of denominations serves better than large notes, particularly in rural areas. Note that Switzerland uses the franc rather than the euro, a detail that still catches out first-time visitors.
Travel FX has traded online for 18+ years, offers over 60 currencies commission-free and carries a 5-star Trustpilot rating from around 32,800 reviews.
