Easily the most popular beach in Australia, Bondi Beach is a great place to soak up the sun. Drop into Bondi Icebergs for lunch overlooking the Pacific Ocean and the Bondi Baths. You can get bunt quite quickly under the Australian sun so remember to slap on the suncream!
There is a lovely coastal walk between Bondi and Coogee. You'll pass through 5 of Sydney's beaches; Bondi, Tamarama, Bronte and Clovelly and ending at Coogee Beach. The walk should take 2-3 hours return.
Tip: Bondi can get pretty busy, so if you're looking for a quieter beach head to nearby Bronte Beach. There are some great cafes and a lovely park for BBQ's.
