The river is a great natural and free asset for the city. Perth Water, the section of the Swan immediately below the CBD, is a superb foreground and mirror to the city -- best seen from South Perth, and stunning around sunset. The South Perth ferry is the easiest way of getting there. Perth Water is shallow, ideal for "messing about in boats," and small catamarans can be hired on the South Perth foreshore. Once past the Narrow Bridge, the river widens out and becomes home to several yacht clubs. Biking along the riverside pathways is also a great way to enjoy the city, the river, and the climate. Rent a bike near the Causeway bridges.
