Clifton Gardens, Sydney

Dive Site: Clifton Gardens, Sydney

Depth:3 to 26 feet (1 to 8 meters)
Visibility:3 to 26 feet (1 to 8 meters)
Location:Sydney, Australia
Best places to dive: The beach entry is easy, and there are toilets, showers and barbecue facilities in the park. Don’t forget to pay for parking. Be careful with the fishermen angling from the jetty, and with the occasional boats landing on the left side of the main jetty. It’s safest to stay underneath it.
When to go:Year-round, especially when other Sydney dive sites are too rough to dive.
