One of my favourite things to do is to walk across the Sydney Harbour Bridge in the morning while there are not many people. The sunrise view is very beautiful and it is very quiet in the morning. It may get pretty busy and a bit polluted if you walk across the bridge in the afternoon or evening. Walking across the Sydney Harbour Bridge requires a certain fitness level so it is perfect if you want to keep fit or do your morning run there. This activity is completely free so it should be affordable for everyone. The Sydney Harbour Bridge is a must to visit if you are travelling around Sydney. I highly recommend that you at least try walking across the bridge once! Don’t forget to bring your water with you.
