One of the best things about living in Sydney is that you have easy access to many different hikes. Most people though don't think past taking a train up to the Blue Mountains.
However there are many other public transport accessible hikes that I have done.
Jerusalem Bay, one of my favourite public transport accessible hikes around Sydney
There is a nice one in suburbs between Epping and Hornsby which is part of the Great North Walk (and a popular bushland area for local teenagers to stash their marijuana plants).
There is also another easy hike between Heathcote and Waterfall train stations in Sydney's south.
One that I have been on many times is to Jerusalem Bay on the Hawkesbury. You hike from Cowan Train Station up to Brooklyn where you can enjoy fresh Hawkesbury oysters and a beer in the local pub before taking the train home.
Do you have a favourite public transport accessible hike in the Sydney area?
The ones that comes to mind are the ones that start at Audley in the Royal National Park.
To get there you would get the train or bus to Sutherland Station. Then you can either catch a bus or walk to the Loftus Tram Museum and then catch a tram ride to the info centre. From here you can go on a number of different walks.
If you are of the more Adventurous type you could walk down to the weir at Audley and start from here.
