Try a walking tour of Sydney. Starting at Circular Quay, the train, bus and ferry station, you can see the Opera house and Harbour Bridge. It is only a short walk past the bridge to the Rocks area, where Sydney was first foundered. This is famous for its markets, art-works, eateries and historic buildings.
In the other direction from the Rocks, past the Opera house, are the Sydney Botanic Gardens. Established 200 years ago the area was once home to a zoo and an exhibition area, but is now dedicated to gardens and some local animal wildlife.
Those individuals not comfortable exploring on their own can try a free tour. There are free walking tours starting at Town Hall Square at 10:30am and 2:30pm every day (just outside Town Hall Train station) and a free walking tour of the Rocks starting at 6pm outside Cadman’s cottage. Donations are welcomed.
Tired of walking?
The Red explorer bus is focused on Sydney site seeing. Including Circular Quay as part of its route it allows passengers to get on and off as many time as they like on a one or two day trip.
Take a day tour of Sydney to see the popular sites. Then try a little exploring on you own. The popular sites are popular for a reason, but there are always the lesser known cafes, museum, beaches and other sites that are worth a half day visit.
