Operastranda
Next to the Operahuset, this 100-meter-long (328-foot) urban beach offers year-round swimming, public saunas, and lounging areas. The water is shallow, making it especially great for kids. Behind the beach, there’s a green park area with a playground, which makes it even more family-friendly—just keep in mind there are no lifeguards on duty. You can grab food and drinks at the Opera’s café.
