Follow the weekend crowd two hours west to the Blue Mountains, Sydney’s popular hilltop getaway. There, spend your days hiking the lush valley.
For an easier jaunt, hop a harbor ferry to the northern beaches on the city’s outer edge and stroll the Victoria Parade in Manly.
Seeking a more tropical escape? Head 138 miles south to Jervis Bay, which looks like the backdrop of The Blue Lagoon: white sands lapped by clear, blue water teeming with rays.
