Yes, Zadar is most definitely worth visiting. Not only is it considered one of the coolest destinations in Croatia, but it's also the perfect base for a sailing holiday. Zadar gives you easy access to many of the stunning islands that lie off the Croatian coastline; sail to charming spots like Dugi Otok or Ugljan before heading back into Zadar at sunset. As you do so, listen to the haunting sounds of architect Nikola Bašić's Sea Organ, a structure of subterranean pipes that create the sound of whale song as the tide ebbs and flows. After sailing around the islands, spend some time enjoying the delights of Zadar. Explore Roman ruins on the waterfront before relaxing with a spot of people watching over coffee in the old town area of Kalelarga. Here you'll find St. Anastasia's Cathedral and St. Donatus Church. Food is a big part of any holiday, and Dalmatian cuisine is becoming known around the world. Slow-cooked lamb stews, octopus cooked in garlic and wine, and sustainably farmed bluefin tuna are all on Zadar's menus, washed down with a glass of wine from the Kraljevski vineyard. Before you leave Zadar, sail to Kornati National Park. Go snorkelling or scuba diving in this uninhabited marine reserve and you may catch a glimpse of some playful dolphins.
