Croatia has an amazing 5,835km of coastline with 1,185 islands in the Adriatic, but only about 50 are populated. The largest island is Krk (near Rijeka) which has a land area of 462 square km. The climate is Mediterranean along the Adriatic coast, meaning warm dry summers and mild winters, with 2,600 hours of sunlight on average yearly - it is one of the sunniest coastlines in Europe!
