Central Cairns is compact enough to explore on foot. Visitors tend to congregate around the Esplanade and city centre, where there are plenty of taxis and bus stops. The public buses cover most areas with reasonable fares, though visitors should note that bus services are less frequent at night and over weekends. The city's 'Sun Buses' run from a central transit terminal and maps and timetables are freely available from hotels and other tourist establishments. Black and white metered taxis operate day and night from ranks throughout the city, or can be flagged down in the street. Car hire firms are plentiful for those wishing to explore further afield. Naturally, boat rides and cruises are also a popular transport option in Cairns.
