Sydney's harbour shapes almost every good walking route in the city, with paths like the one connecting the Opera House to the Royal Botanic Garden, or the longer coastal walk from Bondi to Coogee, offering constant water views and a natural, easy-to-follow structure without needing much navigation.
The central business district itself is fairly compact and walkable, though it includes some genuine hills, particularly around the older parts of town near The Rocks, which adds a bit of elevation to what otherwise feels like a manageable urban core.
Australian sun is strong even on mild-feeling days, so walking here calls for more sun protection than the temperature alone might suggest, especially on the longer, more exposed coastal paths with limited shade.
