I am currently staying in Sydney with a friend and we would like to do some more day trips but are sort of running out of ideas... does anyone have any tips on what places we should definitely see apart from the obvious ones and those that cost $100+?
A few things I would recommend:
Scenic walk from Manly to The Spit: Buy a Daytripper ticket and go to Manly by ferry, then when you get of at Manly turn right and just keep walking until you get to The Spit. The views are stunning and it is very calming to walk through the bush right next to the sea...
Make sure you start early though as you don't want to get caught in there when it is dark - it takes around four hours... buses from the Spit go to North Shore suburbs and probably the city, too.
Coastal walk from Bondi to Bronte: Nice views over the beaches and the coastal line... can go further to a huge cemetery which looks quite amazing... swimming would probably be possible most times of the year, too - and surfing of course!
Botany Bay National Park (Kurnell): Once again, stunning views and lots of animals to be seen... There is a walk to Cronulla which is supposed to be really nice, too. Apparently in winter you can sometimes see whales.
Taronga Zoo: Probably not for everyone, but you will definitely see your native animals here...
Royal Botanic Gardens: Like an oasis in the middle of the city... adjacent to the Opera House with views across the harbour...
More tips would be appreciated!
