Since St-Pierre is part of France, local currency is the euro (€), made up of 100 cents. Canadian and US dollars are also widely accepted in shops and some restaurants, but you’ll usually get change in euros. Note however, that museums, local ferries and any government-run service will only accept euros (and may not accept credit cards) – you’ll need to get at least some euros in cash. There is only one bank, Banque de St-Pierre et Miquelon (Mon–Fri 8.30am–noon & 1.30–5pm), on the harbourfront, near L’Arche Musée, which can change money and has an ATM; there is also an ATM next to Bar Rustique on rue Albert in the centre.
To clear St-Pierre et Miquelon’s immigration and customs control, EU and US nationals need a passport (providing visa-free entry for up to thirty days); Canadians just need photo ID. Entry requirements are essentially the same as visiting France for other nationals, so check the latest requirements. For medical emergencies, dial t 15, police t 17.
