Not surprisingly, the best time to go on a family holiday to Croatia is during the school holidays, with most holiday companies offering family fun from Easter onwards, although some only kick in properly in June-Aug. Oct half term is superb in Croatia, however. A few companies still offer holidays then, when the crowds have gone as it is the tail end of the season. But it does mean that there is lots of space to really let rip, adventure wise. And parents can toast a successful autumn adventure with a glass of local wine. Because this is not only quiet time, but also grape harvest time.
