Only in the summer months is there more informality, and visitors should note that air-conditioning is not normal in offices, public buildings, city transport or the cheaper hotels. In winter, a heavy coat is advisable together with stout, waterproof footwear - even when the temperature is below freezing, the use of salt on footpaths turns snow to slush. No special precautions need to be taken. Tap water in Zagreb is perfectly drinkable and there is a wide variety of excellent bottled waters on sale. Streets are kept free from garbage and washed regularly in the summer.
Pharmacies are well-stocked, and doctors, dentists and opticians of good quality, if expensive.
Travel insurance is advisable because, although the reciprocal health agreement between the UK and Croatia allows free treatment, this can only be in public sector clinics, which are very busy. Hygiene standards are high, although normal precautions about washing fruit before consumption should be taken. Smoking is forbidden in all public transport and public buildings. Food and drink Croatia is a cafe society. Street cafes abound in the warmer months, but generally they only serve drinks.
