Spoken languages: Portuguese is the official language, but English is spoken all along the coast.
Local habits and customs: Do respect the traditional siesta hours between 1 pm and 3 pm when smaller shops might close; otherwise, dining is a leisurely affair and often starts late, around 8 or 9 pm. There is no hard and fast rule for tipping, which is not really a Portuguese custom; that said, in a café, restaurant or for taxis, it's customary to round up the bill to the nearest euro or, for big amounts, the nearest note.
Currency: Portugal uses the Euro. ATMs are easy to find, and most establishments accept major credit cards. For smaller purchases in markets or cafés, having some cash handy is a good idea.
Getting around: Carvoeiro is small and easy to navigate on foot. For nearby beaches and attractions, buses connect major towns and cost around €1.50–€3 per journey. Taxis and car hire are popular options for exploring further afield, with rental cars starting at around €30 per day.
Electricity and plug types: Portugal uses the standard continental 220 volts, and Irish travellers will need a two-pin adaptor for their devices.
Time zone: Carvoeiro is in Western European Time (WET), the same as Irish time. Daylight Saving Time is observed, so clocks move forward by an hour in summer.
