Sydney has a good network of buses, trains and ferries that make getting around the city and the surrounds easy. The bus network is the most extensive and cheapest mode of public transport, but can be slow due to traffic jams. There are also several hop-on hop-off Explorer buses for tourists that take in the major sights and surrounding beaches. The underground city centre train loop is the fastest way to get around, but many of the tourist areas, including Darling Harbour, Bondi Beach and Manly, can only be reached by further ferry or bus connections. The most pleasurable way to get around is by ferry - the main terminal is at Circular Quay. There is also a 10-minute monorail loop from the city centre to Darling Harbour and back, and a Metro Light Rail 'tram' system between Central Station and Wentworth Park in Pyrmont. In addition, metered taxis are plentiful and fairly economical. Hiring a car for short visits is not recommended due to heavy congestion (in peak hours) and limited parking in the city centre.
