Things to do
Sydney grew around a vast natural harbour, and water sets the pace: ferries leave Circular Quay for beaches and suburbs while the office towers of the centre stand a short walk from historic lanes. Plan each day around one side of the harbour to avoid long crossings.
Bondi to Coogee coastal walk
Follow the six-kilometre cliff path from Bondi Beach to Coogee, passing lookout points, small coves and ocean pools. Start in the morning, carry water and take the bus back from Coogee.
Ferry to Manly
The ferry from Circular Quay to Manly passes the Opera House and ends beside an ocean beach. Give the day to the water and the sand; the return crossing at sunset gives the best view of the harbour.
The Rocks and the Opera House
Walk around Sydney Opera House along the waterfront, climb into The Rocks and continue beneath the arch of Harbour Bridge. Half a day covers the route, and it costs nothing unless you go inside the buildings.
Where to stay
The Rocks
The Rocks is the city's oldest quarter, right by Circular Quay, with sandstone warehouses, pubs and a view of the bridge. It suits early ferries, but evenings are loud and rooms are expensive.
Surry Hills
Surry Hills suits travellers who want cafés, small restaurants and a walk to Central Station. It is calmer than the centre, though you will need a tram or bus to reach Circular Quay.
Bondi
Bondi brings beach life into the city: surfing, swimming and a promenade lined with cafés. The centre is about twenty minutes away via Bondi Junction, and evenings here stay quiet. Surfers arrive at dawn.
Getting to and around Sydney
Kingsford Smith Airport lies ten kilometres from the centre; the Airport Link train reaches Central and Circular Quay in about twenty minutes. Trains, light rail and ferries form the main network and run on the one Opal card. Ferries connect Circular Quay with Manly, Taronga Zoo and Watsons Bay, light rail serves Randwick, and buses cover Bondi and Coogee.
Three days in Sydney
Circular Quay, the Opera House and The Rocks
Begin at Sydney Opera House, follow the waterfront into The Rocks and climb to the lookout by Harbour Bridge. Return to the water after dark to see the Opera House lit.
Bondi and the coast
Take the train to Bondi Junction in the morning, walk down to the beach and follow the coastal path to Coogee. After a swim, head back to Surry Hills for dinner in a small restaurant.
Manly and the north shore
Board the ferry to Manly, walk along the beach and continue to the North Head lookout. The afternoon return crossing leaves time for the Royal Botanic Garden beside Circular Quay.
