Ploče Beach is well-suited for families, being Rijeka's main modern beach complex with good facilities and safety features. The beach offers various entry points including concrete platforms and pebble areas, some with gradual water access suitable for children. Lifeguards are typically present during peak season. The complex includes children's playgrounds, changing rooms, showers, and nearby cafés. Water quality is monitored as an urban beach. While not a traditional sandy beach, the developed infrastructure makes it practical for families. The urban setting means crowds during summer weekends, so weekday mornings offer a better experience for families.

Ploče Beach is accessible year-round as an urban beach, but the best swimming conditions are June through September. July and August are busiest with full facilities operating but expect significant crowds, especially weekends. June and September offer a good balance of warm weather and fewer visitors. The beach can be enjoyed in shoulder seasons (May, October) for sunbathing and the seaside promenade, though swimming may be chilly. Weekday mornings are quieter than afternoons and weekends when locals visit after work. As a city beach, it serves Rijeka residents throughout the warm season, so timing depends on your crowd tolerance.
