The Waikiki Aquarium, located right on the shores and run by the nearby university, attempts to recreate diverse tropical Pacific reef habitats to function as home to a number of aquatic species, including some rare fish species from the Northwestern Hawaiian Islands and the moon jellyfish.

Knez Mihailova Street is the pedestrian area that unifies Belgrade's beautiful architecture. It leads to the Belgrade Fortress and Kalemegdan Park on one end, and to Terazije and the iconic Terazijska česma drinking fountain near Hotel Moskva on the other, offering a splendid view of the Sava river valley. Inside tip: Take a detour to Kosančićev venac, the oldest part of Belgrade outside the fortress. This charming elbow-shaped street is home to Princess Ljubica's Residence, the Building of the Patriarchate of the Serbian Orthodox Church, and the Cathedral Church of St Michael the Archangel, all of which are sure to captivate you with their elegance.

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.

The Cook Islands Christian Church in Avarua is a striking old building crafted from white coral, originally erected in 1853. It's well worth a visit, particularly for its intriguing graveyard. In front of the church, you’ll find a monument dedicated to Papeiha, a Polynesian missionary, and the grave of Albert Henry, the first Prime Minister of the independent Cook Islands, complete with a life-size bust.
