Two bus companies, Red Bus and Go Bus Christchurch, and a ferry service are jointly marketed as Metro, plying a comprehensive range of routes throughout the city and outer reaches. Central Station is at Lichfield and Tuam Sts. The ferry connects Lyttleton to Diamond Harbour. Christchurch Tramway plies a one-way circuit around the CBD, primarily for tourists. Beyond that, cycling is a great option for getting around a predominantly flat city.
