The public transport system in Managua consists of buses, taxis, and cycle taxis. Urban buses tend to be old and poorly maintained, although the city's network is fairly extensive. Buses display their route number, and a list of routes is posted on signs for the bus stops.Despite this, transport information can be scarce and asking locals for assistance is recommended. Interurban buses operate at terminals in the city. There are two main kinds of buses: ordinarios are larger buses with lower fares and longer travel times, while espresos are smaller, more comfortable buses that travel faster but charge more.Taxis are usually the most convenient means of transport in the city and are widely available. They generally do not have meters and negotiating a fare before setting off is important, especially since they tend to try overcharge tourists.
