Sydney is one of the most beautiful cities with amazing beaches along its 70 km of coastline. To explore all the hidden beaches in lovely spots in detail requires a couple of days. Most beaches are very well maintained and ideal for swimming. Popular spots like Bondi, Coogee and Cronulla have a lifeguard on duty and have strict regulations for swimming and surfing. A warm summer weekend attracts large crowds to Bondi and Coogee Beaches which are popular locations for swimming and surfing.
