Island-dotted region in the north
Flights from the UK to Croatia take around 2 hours 30 minutes.
July and August are the hottest months (temperatures can reach into the mid-30s) and attract the most visitors. June, September and October are great months to visit. It's less busy, plus the weather tends to be warm and dry (spot on for sightseeing).
Tipping is becoming more commonplace in Croatia, especially in more upmarket establishments where around 10% has become the norm. In bars and more casual restaurants, just leave the coins in your change. At your hotel, tip porters and maids 15 kuna or so. Taxi drivers don’t expect a tip, but it’s a nice gesture to round up the fare.
The official language of Croatia is Croatian. English is widely spoken too, so getting by is easy.
