Bundeena to Marley beach track in Royal National Park is one of the most spectacular coastal walks in Sydney. It follows the cliff tops along the Illawara coastline for 4km until bringing you to a largely deserted Marley beach.  And if the stunning views are not enough, the clifftops along the walk are excellent for spotting Humpback whales during their migrations from August to October. #coastline #hiking #views #photography #beach #whalewatching #swimming
