From Lisbon and Porto to the Algarve, Portugal is firmly on the euro, so buying euros before you fly is the sensible move. A commission-free provider such as Travel FX lets you buy euros online at a clear rate, ready for collection or delivery before you travel.
Cards work in most places, but cash is useful for cafes, markets, tips and smaller venues, particularly away from the main tourist areas.
Airport exchange desks are convenient but rarely the best value. Buying your euros at home in advance almost always leaves you better off.
Travel FX offers more than 60 currencies, has over 18 years of trading history and holds a 5-star Trustpilot rating from around 32,800 reviews, with simple online ordering.
Sort your euros ahead of time and start the holiday relaxed.
