Holidays in Croatia in December are best spent in Dubrovnik or Pula. Here the temperature sometimes reaches +15°C, while in Zagreb it is much cooler and the humidity is higher. During a vacation in Croatia in winter you can catch the end of the white truffle harvesting season, fish on the lakes or go on vacation to one of the thermal resorts of the country. But the most popular are ski tours to Croatia in December. This month is the start of the ski season.
