Jerusalem Bay trail in Kur-rin-gai National Park is a good opportunity to get a taste of the mammoth 250-km long Great Northen Walk. The trial runs for 2.5 km from Cowan train station to Jerusalem Bay through typical Australian eucalypt woodland.  For an extra challenge, you can continue all the way to Brooklyn and catch the train back from Hawkesbury River station. #mountains #hiking #scenery #forest
