Croatia Basics

Time: Local time is GMT +1 (GMT +2 from last Sunday in March to the last Sunday in October).
Electricity: Electrical current is 230 volts, 50Hz. European style round, two-pin plugs are standard.
Language: The official language is Croatian.
Health: No vaccinations are required, however there is a risk of tick-borne encephalitis for those travelling in forested areas or who consume unpasteurised dairy products. Typhoid and Hepatitis A vaccinations are also recommended. The bird flu virus was found in dead migratory swans and stringent measures have been taken by the Croatian authorities to contain the virus. Travellers to Croatia are unlikely to be affected, but should avoid any contact with live birds and ensure poultry and egg dishes are well cooked. Medical care is fairly good, with free emergency medical care available to UK citizens with a European Health Insurance Card (EHIC), though some medicines are in short supply in public facilities. Non-UK nationals are advised to invest in health insurance.
Tipping: In tourist or upmarket restaurants a tip of 10% will be appreciated, but otherwise it is usual to round up the bill if the service has been good unless a service charge has already been added. Tour guides expect to be tipped. Most other services receive a small tip by rounding up the bill.
Safety: Most visits to Croatia are trouble-free, and there is no particular threat of terrorism. Busy tourist areas are prone to petty theft. Outside the normal tourist routes travellers should be aware that unexploded mines might remain, particularly in Eastern Slavonia and the former Krajina.
Customs: Passports, or some form of identification, should be carried at all times.
Business: Business in Croatia is conducted in a formal manner; punctuality is key, dress should be smart and conservative (suits and ties are the norm) and polite greetings are made with a handshake. Titles and surnames are usually used unless otherwise indicated and business cards are exchanged at the beginning of a meeting. English and German are widely spoken, but any attempt at speaking some Croatian will be appreciated. Women tend to hold high positions in business and are well respected. Building a good working relationship is important in Croatia and it is useful to work with a reliable local partner. Although Croatia appears typically European in its dealings, business can take some time to conclude. Business hours are usually 8am to 4pm Monday to Friday.
Communications: The international access code for Croatia is +385. The outgoing code is 00 followed by the relevant country code (e.g. 0044 for the United Kingdom). The city code for Zagreb is (0)1 and (0)20 for Dubrovnik. Public phones take phone cards, which can be bought in post offices and hotels. GSM operators have active roaming agreements with most international networks, and cover most of the country. Internet cafes are available in the larger towns and cities.
Duty Free: Travellers to Croatia can enter the country with the following items without incurring customs duty: 200 cigarettes or 50 cigars or 250g of tobacco; 1 litre wine and 1 litre spirits; 250ml of eau de cologne and one bottle of perfume. Regulations apply to firearms and radio instruments. No item of archaeological, historical, ethnographic, artistic, cultural or scientific value may leave the country without a license issued by the appropriate authorities.
