- Currency
- The euro (EUR): the country switched to the euro at the start of 2026. Cards are accepted in towns and resorts, but cash is useful in mountain villages and small shops.
- Sockets
- Sockets of types C and F, 230 V, 50 Hz. Phones and chargers from Kazakhstan work without an adapter.
- Emergency
- The single emergency number is 112. Save it and your accommodation address before heading into the mountains.
- Time difference
- In winter Bulgaria is 3 hours behind Kazakhstan, and in summer, after the switch to summer time, 2 hours. When it is noon in Astana, it is 09:00 in Sofia in winter and 10:00 in summer.
- Language and alphabet
- The official language is Bulgarian, written in Cyrillic, so signs are easy to read. In tourist places you can usually get by in English, and in smaller towns a translator helps.
- Roads and vignette
- On a rental car, driving on national roads outside city streets requires an electronic vignette. Ask the rental company whether one is registered for your car.
- Tipping and water
- Tipping is optional and people often round up the bill. Tap water in towns is usually drinkable, but many travellers take bottled water.
- Entry
- Check current entry rules for citizens of Kazakhstan before the trip.
