We recommend visiting our ceremony venue before or after the wedding, as it is such a beautiful place to do a walk with views of the bridge, Opera House, and Sydney Harbour. A great place to start is a walk around The Rocks then venture to the Opera House, which will then lead you into the Botanic Gardens.
If there is one coastal walk you have to do whilst in Sydney, its the 6km Bondi to Coogee walk where you will get to see stunning views, beaches, parks, cliffs, bays and rock pools. You can take the hop on hop off tour bus or get to Bondi via the train + a short bus ride to the beach.
If you have time, we would highly recommend doing a 1 hour day trip from Sydney to Royal National Park for scenic views. Although it will be closer to winter, it would still be a great time to visit. We did a winter caravan trip along this route and it was perfect sunny days driving along the coast.
