My friend and I arrived in Sydney Monday night. Yesterday we took the ferry to Manly and did some walking around which was great. We leave on Saturday so we only have 3 days left. A couple of questions. We were thinking about making a day trip to the Blue Mountains. Should we scratch that idea if it continues to rain as predicted? If we attempt the Blue Mountains on a rainy day what is the best way to do this? We will still walk around the Rocks and see the Opera House--probably today. Any other ideas for rainy day activities? What is the best restaurant for great seafood? We are staying in the Circular Quay area. Thanks for your help!
