French Guiana Currency & Money Guide: Exchange, Cards, and Tips

French Guiana uses the euro (€), and the best everyday strategy is to combine a Visa or Mastercard with a modest amount of cash. Cards and contactless payments work reliably in Cayenne, Kourou, Remire-Montjoly, major hotels, and larger restaurants, while markets, small cafés, rural communities, and interior excursions may require euros in notes and coins.\n\nFor 2026 planning, budget approximately €66–€132 per person per day for standard travel, excluding international flights, according to current travel-cost estimates. Market meals often cost €4–€8, while a simple sit-down meal is roughly €12–€18. Withdraw euros from bank-operated ATMs, choose to be charged in EUR rather than Singapore dollars, and keep a backup card and cash reserve. French Guiana tipping is optional: round up or leave around 5–10% for notably good service. The Hello app can track spending in euros and Singapore dollars with automatic exchange-rate conversion, making it easier to stay within budget.

The official French Guiana currency is the euro, so travellers from Singapore should plan every purchase around EUR prices rather than expecting local use of Singapore dollars, US dollars, or Brazilian reais. French Guiana is an overseas department of France and uses the same euro notes and coins as mainland France.\n\nThe French Guiana exchange rate against SGD changes daily. As a practical example, if €1 equals approximately S$1.45, a €10 meal would cost about S$14.50 before card or bank fees; always check the live rate before converting a larger amount. The rate offered by your bank, card network, or ATM may differ from the mid-market rate because of foreign-exchange margins.\n\nUseful euro denominations include €5, €10, and €20 notes, plus €1 and €2 coins. Avoid carrying only €50 or €100 notes, since market vendors and small cafés may not have enough change. The Hello app’s multi-currency expense tracker automatically converts purchases between EUR and SGD, while AI receipt scanning can read receipts in different languages and currencies. This is especially useful when splitting a shared car rental, accommodation, or rainforest tour with friends.

The most practical French Guiana money tip is to withdraw euros from a bank ATM in a major town before travelling into remote areas, because cash machines become scarce outside the coastal urban corridor. ATMs, known locally as DABs or distributeurs automatiques de billets, are available at Cayenne Félix-Éboué Airport and in Cayenne, Kourou, and Saint-Laurent-du-Maroni.\n\nBank-operated machines, including those associated with major French banks such as BNP Paribas and Crédit Agricole, are generally preferable to independent cash machines because their fees and exchange terms are usually clearer. International Visa and Mastercard cards are the safest choices. Typical foreign-card or operator fees may range from about €2–€5 per withdrawal, while individual withdrawal limits are often around €300–€500, although the exact amount depends on the bank and card issuer.\n\nBefore confirming a withdrawal, select EUR or “without conversion” if the ATM offers to charge your account in SGD. This declines dynamic currency conversion, which can apply an unfavourable exchange rate. Carry enough cash before visiting Mana, Apatou, Maripasoula, Saint-Georges, or Grand-Santi, where ATM access can be limited. Notify your bank about the trip and keep a second card separately from your wallet.

Visa and Mastercard are widely accepted in French Guiana’s cities, but contactless payment and digital wallets should be treated as conveniences rather than guaranteed payment methods everywhere. Hotels, supermarkets, car-rental companies, larger shops, and restaurants in Cayenne and Kourou commonly accept international cards, with chip-and-PIN and “sans contact” terminals increasingly normal.\n\nCash remains important at produce and craft markets, small family-run cafés, roadside stalls, informal transport points, and remote accommodation. American Express is less consistently accepted, so it should not be a traveller’s only card. Some businesses may also impose a small card surcharge, although this is not universal. Ask about the total before tapping or inserting your card.\n\nFrench Guiana does not have the same dependence on tourist-oriented payment apps found in some Asian destinations. WeChat Pay and PayPay are not reliable general-purpose options for visitors, and local acceptance of overseas wallets can be limited. A physical Visa or Mastercard, a phone wallet such as Apple Pay or Google Pay where supported, and cash provide better coverage. Keep your phone charged, and carry a backup card because an offline terminal, weak connection, or card-security block can interrupt payment.

French Guiana tipping is optional because restaurant bills generally include service, but rounding up or leaving 5–10% is a friendly way to recognise excellent service. Tipping is not expected after every routine transaction, and staff will not usually regard a zero tip as offensive when service has been ordinary.\n\nAt a casual restaurant, rounding a €17.50 bill to €18 or €20 is sufficient. For especially attentive service at an upscale restaurant, leaving around 5–10% is appropriate if no additional service charge has already been added. Check the bill for wording such as “service compris” before deciding.\n\nGuides and drivers are more likely to receive a tip when they have made a trip safer, more informative, or more enjoyable. For a memorable rainforest, Kaw marsh, Îles du Salut, or Guiana Space Centre excursion, approximately 5–10% of the tour price is a reasonable gesture, divided among the group if several people participated. Hotel porters and housekeeping staff may receive a few euros for exceptional help, but this is discretionary. The Hello app can split a tip and shared tour expense across multiple currencies, automatically converting each traveller’s share.

A realistic 2026 French Guiana budget is about €66–€132 per person per day for standard travel, although accommodation, car hire, excursions, and launch-event dates can push costs higher. Planning meals and transport carefully can make a noticeable difference because prices are often higher than visitors expect for an overseas department of France.\n\n| Expense | Typical 2026 price | Money-saving approach |\n|---|---:|---|\n| Market or street-stall meal | €4–€8 | Eat at local markets rather than tourist restaurants |\n| Simple sit-down meal | €12–€18 | Choose lunch specials and ask for tap water |\n| Mid-range dinner | €20–€35 | Share starters and avoid unnecessary hotel dining |\n| Economy car rental | €35–€60 per day | Compare total insurance and fuel costs |\n| Îles du Salut return catamaran | €50–€60 | Book early and confirm inclusions |\n| Kaw marsh guided tour | €60–€90 | Compare group tours rather than private departures |\n\nCayenne’s Central Market and Madeleine Market are useful for affordable meals, while Hmong noodle soup in Cacao can cost roughly €3–€6 on Sundays. Withdraw larger amounts less frequently to reduce fixed ATM fees, but do not carry all your travel money together. Track receipts in Hello by category—food, transport, activities, and accommodation—to spot overspending before the next excursion.

The short answer is that travellers should bring a Visa or Mastercard, withdraw euros in major towns, and keep cash available for markets, rural travel, and small businesses. The following answers cover the most common French Guiana currency and payment questions.\n\nCan I use Singapore dollars in French Guiana?\nNo. Singapore dollars are not normal spending currency. Convert through a bank, card network, ATM, or exchange service and pay in euros.\n\nShould I exchange money before arrival?\nBringing a small euro reserve is sensible for transport, snacks, or an arrival purchase, but bank ATMs at or near Cayenne Félix-Éboué Airport can also provide euros. Avoid exchanging a large amount at an airport counter without comparing the rate and commission.\n\nAre ATMs available everywhere?\nNo. They are concentrated in Cayenne, Kourou, Saint-Laurent-du-Maroni, and other larger towns; access can be limited in places such as Maripasoula, Grand-Santi, Mana, and Saint-Georges.\n\nIs tipping compulsory?\nNo. Service is commonly included. Round up or leave 5–10% for exceptional restaurant service, guides, or drivers.\n\nHow can I stay connected while managing expenses?\nBuy and activate Hello eSIM for French Guiana before departure so maps, banking alerts, translation, and the Hello app remain accessible on arrival. Hello offers eSIM connectivity in 200+ countries, with live-updated plans and instant activation.
