Sydney Bike Tours

You can climb to the top of the arch of the bridge. For those who are good with heights and enjoy a spectacular view of the harbour, there are organised climbs to the top of the bridge. This climb is more demanding than climbing a set of stairs, although it is not so demanding as the name implies. You will be fitted with special climbing suits and secured by safety tethers, you must be 10 years old or over to take the climb. The climb takes 3½ hours and a group leaves every 10 minutes. You can ascend during the day, at twilight and at night. Book your climb as early as possible as the climb is very popular. Loose items including cameras are prohibited on the climb; Bridge Climb staff will take a photo of you, but you may not take photographs yourself.

The last relic of the small, relatively plain buildings that once ringed Sydney Cove in the early colonial period, this small sandstone cottage was built in 1815-1816. The building has survived largely because of constant government or institutional ownership. Restoration began in 1972 and the building is now used as an information centre by the National Parks and Wildlife Service. The Cottage was built by the water side, but with reclamation over the years, the shoreline of Sydney Cove is now 100 metres distant.

Follow Argyle St through this historic sandstone road cutting made between 1843 and 1867, made with the effort of both convict and paid labour. The sights and sounds of the convict labour, still bound in chains and working only with crude tools, horrified the locals and the cutting was abandoned after just three years. A long interlude lasted before the city council eventually linked Millers Point and The Rocks together with the use of paid labour and explosives.

The colony's first military church, it is still an active Anglican church.

Art museum focusing on work by contemporary Australian artists. Housed in a fabulous 1930s art deco building, former location of the Maritime Services Board and facing onto the western side of Circular Quay and Sydney Cove, the MCA has been dedicated since its opening in 1991 to showcasing great works of modern and contemporary art in all media. One wing is newer, contemporary architecture; the other is a historic building used for port administration until the 1930s. The museum runs some arts education programs for children and disabled people.

Australia's oldest observatory. It has a variety of exhibitions, a “beanbag planetarium” and of course, telescopes. The parks and views of the harbour from the Observatory Hill are exceptional. It's worth a visit even if you have no interest in astronomy and are not even going into the building. You can book a night tour guided by an astronomer, where you're allowed to use the telescope and see what is visible during night time. The old telescopes here aren't the most powerful around; the portable telescopes set up are just as powerful as the large ones in the domes. It makes for a fun, informative night out. Children are catered for in both the daytime and evening sessions.
