Kalardovo Beach is a lovely sandy (or small gravel) beach, located near the airport. To get to the beach, you can take a taxi or go by car as it's not very close to the city. The beach is pretty specific - you can watch airplanes arriving and departing from the airport and hear their sounds that are pretty loud. And the beach is pretty shallow, so it's better for families with kids - it's very safe there. And watching planes could be really cool entertainment for kids as the addition to the playground on the beach.
On the beach you can rent loungers and umbrellas, have some food at the restaurant right on the beach. There is a very beautiful view to Tivat airport and the Riviera. Surrounded by mountains, you can enjoy fantastic bay views. The water is very beautiful, clear and transparent at the sea. There is a big parking next to the beach which is very convenient. There is a very beautiful small island of flowers close to the beach that you can also visit while resting on the beach.
