Things to do
Perth spreads along the Swan River, with the city towers facing Kings Park across the water. It is a spacious, sunny place: trains link the centre with Fremantle and the beaches, and free CAT buses loop through the districts.
Kings Park
Climb into Kings Park by the steps above Elizabeth Quay and walk through the botanic garden. The lookout shows the towers and the river; return through the park to the centre.
Rottnest Island
The ferry from Barrack Street jetty reaches Rottnest Island in about ninety minutes. Hire a bike to ride between the white-sand bays and take a late ferry back. Quokkas live there and nowhere else.
Cottesloe and Fremantle
The train reaches Fremantle in half an hour: walk the port streets and the market. On the way back get off at Cottesloe and swim at the town beach. Cottesloe has a long ocean promenade.
Where to stay
City centre
The centre suits a short visit, with Elizabeth Quay, the station and Kings Park close together. The office district empties in the evening, so head to Northbridge for dinner. Northbridge is fifteen minutes on foot.
Northbridge
Northbridge works for restaurants, bars and Asian cooking. The centre is ten minutes on foot, nights are noisy, and the hotels are plain. Cross the footbridge to reach the station and centre.
Fremantle
Fremantle sits at the mouth of the Swan, with a port, a market and old warehouses. It suits quiet days by the water, though the train to the centre takes half an hour.
Getting to and around Perth
Perth airport connects to the centre on the Airport Line, with trains reaching Perth station in about twenty minutes. Transperth trains are the main way around and run to Fremantle and the beaches, while free CAT buses loop through the centre. A car is worth hiring only for longer trips, such as the wine regions to the south.
Three days in Perth
Centre and Kings Park
Walk the Elizabeth Quay waterfront, then climb into Kings Park to the botanic garden. At sunset return to the park lookout over the river, and ride to Northbridge for dinner afterwards.
Rottnest
Take the morning ferry to Rottnest, hire a bike and ride to the bays on the western side. Come back towards evening and eat by the water in Fremantle. Hire a mask and snorkel there.
Fremantle and Cottesloe
Look round Fremantle's port and market, then take the train to Cottesloe. After a swim, return to the city and walk the Swan riverfront. Lunch at a café by the beach in Cottesloe.
