Visas. All visitors must complete an online pre-registration before arrival at ease.gov.cv. Citizens of the EU, UK, US, and several other countries can get a visa on arrival or have it added to their online registration. Check current requirements before you travel -- the rules change periodically. Your passport must be valid for at least six months beyond your return date.
Money. The currency is the Cape Verdean Escudo (CVE), pegged to the euro at a fixed rate of roughly 110 CVE to 1 euro. You cannot buy escudos outside Cape Verde, and you cannot exchange them back easily when you leave, so do not withdraw more than you need. ATMs are available in the main towns on the larger islands, but they are sometimes out of order. Visa cards work widely; Mastercard is less reliable. Euros are accepted at some hotels and tourist businesses, but for everyday use -- markets, restaurants, transport -- you need escudos. Bring some euros in cash as a backup.
Language. The official language is Portuguese, and that is what you will see on signs and documents. In daily life, everyone speaks Cape Verdean Creole (Kriolu), a Portuguese-based creole with West African influences. Each island has its own variant. English is not widely spoken outside tourist areas, but you will get by with basic Portuguese or even Spanish in a pinch. Learning a few words of Kriolu goes a long way with locals.
Safety. Cape Verde is generally safe by regional standards, but petty crime is a real concern in the larger towns, particularly Praia and Mindelo. Pickpocketing and bag-snatching occur at markets, on beaches, and around nightlife areas. Muggings happen after dark in quieter streets. Use common sense: do not flash valuables, avoid walking alone at night in unlit areas, and be alert around ATMs. The smaller islands are very safe.
Electricity. Cape Verde uses European-style 220V plugs (type C and F). Bring an adapter if you are coming from the US or UK.
Internet and phones. Mobile coverage is decent on the main islands. Local SIM cards from CV Movel or Unitel are cheap and easy to buy. Wi-Fi is available at most hotels and many restaurants, though speeds can be slow, especially on the smaller islands.
Health. No special vaccinations are required for Cape Verde, though routine travel vaccinations are recommended. Tap water is not safe to drink on most islands -- stick to bottled water. The sun is strong year-round; bring good sunscreen. Medical facilities are basic outside Praia and Mindelo, so travel insurance with medical evacuation cover is a good idea.
