The Mio network organized by the Communauté de Communes de Millau Grands Causses serves Millau and Creissels town centers, outlying districts, public facilities and services. It is structured around 4 urban bus lines.

Mio aims to be a network serving as many people as possible. That’s why the network has been built with the aim of offering an attractive range of services:

• useful for as many people as possible, with timetables designed for employees and schoolchildren alike, enabling them to travel for administrative purposes, shopping, leisure activities, etc. ;
• easy to understand, with recurring timetables at regular intervals to make them easier to remember;
• clear, by offering a consistent range of services all year round, from Monday to Friday, as well as on Saturdays and during school vacations and summer vacation.
