Waterparks: Easily the best place to take children is the gleaming Aqua Magic water park at the southern entrance to Mamaia, which has all the requisite slides and chutes.
Beaches: While Constanța has a few beaches of its own, those in Mamaia, just north of the city, are the ones to head for; calm and mostly shallow waters, there are also plenty of amenities, including sunbeds, umbrellas and beachside cafés - plus lifeguards.
Aquariums: The only one of its kind in the country, Constanța’s Aquarium showcases a variety of marine life from the Black Sea, including fish, turtles and seahorses. Part of the Natural Sciences Museum Complex, the Dolphinarium is another big hit with children.
