Transport in Mauritius is characterized by the network of roadways, ports, and airports. The island was originally only accessible by boat until 1922, when the first flight landed in Mauritius. Mauritius has a widespread bus network with around 220 bus lines and roughly 900 bus stops.They are operated by a number of major companies (National Transport Corporation, Mauritius Bus Transport, Rose Hill Transport, Triolet Bus Service, United Bus Service, Luna Transport and Perle de la savanne) and various individual operators which are organized in regional Bus Owners Co-operative Societies (BOCS). The bus prices are regulated by the Government of Mauritius. However, there is no such thing as an operator independent ticket which could be used across the island.
