2 Best Sights in Slavonia, Croatia

A 20-minute walk across Osijek's pedestrian bridge over the Drava, and across from Trvđa, is Copacabana, a pleasant and spacious aquatic-recreation complex that includes pools, a waterslide, a restaurant, and plenty of willow trees. In August it hosts the popular five-day Pannonian Challenge, an extreme sport and music festival. Impossible to miss if you stroll along this section of the river, it operates from mid-June through mid-September, daily from 10 to 8 pm (weekends from 9 to 8)

Offering old-world Viennese-style elegance, the Kavana Waldinger is Osijek's finest café. Part of the Hotel Waldinger family—which also includes the trendier, more stylish Gold by Waldinger café across the street—it is a wonderful place to relax over a cocktail, coffee, or spectacularly indulgent cake.
