The bus network is extensive, but can be slow. The most pleasant way to get around is by ferry. A trip on the Manly Ferry is the best way to experience the harbour if you can't charm someone into taking you sailing. The Monorail is an elevated toy train that shuttles uselessly between the city and Darling Harbour. Sydneysiders either love its sub- Bladerunner futurism or thinks it's a godawful eyesore, depending on their aesthetic bent.
Taxis are plentiful and car and bike hire are widely available.
