I was able to go on two walks last week, Old Cremorne Wharf to Milsons Point and the other from Scrarborough Beach to Thirroul.  At 7 -8 kms each it was great walking especially as the Harbour walk was in great weather.    At Coledale,which is the beach between Scarborough and Thirroul, the tide was up so we had to walk up on the cliffs instead of rock hopping around.  Maybe next time.
