It’s known as the gateway to Krka national park and the Kornati islands, but this 1,000-year-old city has enough in itself to keep visitors happily busy for days. A slow amble along its waterfront goes past bars, restaurants and the 15th-century Cathedral of St James, a Unesco world heritage site with a blend of gothic and renaissance architecture. In the labyrinthine old town are several of Šibenik’s fortresses, including Sveti Mihovila, a magical spot for outdoor concerts in summer. There’s also the newly renovated Barone fortress, which has stunning views. Cool off at Plaža Banj, a pebbly blue-flag beach north of the old town.
