Cycling is an excellent way to explore Perth. Kings Park has some good bike tracks and there are cycling routes along the Swan River, running all the way to Fremantle, and along the coast. Bikes can be taken free of charge on ferries at any time and on trains outside of weekday peak hours (7am to 9am and 4pm to 6.30pm) – with a bit of planning you can pedal as far as you like in one direction and return via public transport. Bikes can't be taken on buses at any time, except some regional coaches (for a small charge). For route maps, see www.transport.wa.gov.au/cycling/ or call into a bike shop.
The whale-watching season runs from mid-September to early December, when 30,000 cetaceans take the 'Humpback Highway' up the coast. Tour operators offer either a refund or a repeat trip in the unlikely event that whales aren't spotted. Tour boats are fitted with underwater hydrophones, so you can also listen to the whales singing.
