The Seychelles' unique marine biodiversity and appealing crystal-clear waters create the perfect conditions for underwater discovery. For snorkelling, head to one of the best sites of the Indian Ocean - Sainte Anne Marine National Park - or take advantage of the once-in-a-lifetime opportunity to swim alongside whale sharks on Mahe. Diving is another way to get close and personal with reef inhabitants (humphead parrotfish, octopus, various types of sharks - including hammerhead, if you're in luck). Seychelles Underwater Centre

Ada Ciganlija, Belgrade's most renowned summer resort, has transformed from an island to a peninsula, becoming the city's largest and most picturesque recreational spot. The Savsko lake is encircled by over 7 km of Blue Flag-awarded beaches, offering myriad ways to enjoy hot summer days. In summer, Ada Ciganlija turns into a bustling hub, attracting over 100,000 visitors daily (up to 300,000 on weekends) for swimming, sports, or leisurely afternoons in beachside cafés. In contrast, autumn and winter bring a quieter atmosphere, with a scenic promenade lined by cafés and nightclubs, although the lake's ice is too thin for skating. With more than 50 open-air sports facilities, including a golf course and cable-ski circuit, as well as courts and pitches for various sports and extreme activities like bungee-jumping and paintball, there's no shortage of action. The area's restaurants offer traditional city fare, particularly fish specialities, while bars and floating river clubs provide vibrant nightlife.
