This is the company that operates the tram system of Montpellier and its suburbs. There are 4 lines…read morecrisscrossing the city which is far more than what bigger cities like Nice has (only 1 line so far). The lines run smooth for the most part although we happened to take an evening ride to Odysseum on Line 1 from Comedie and it broke down. However, the matter was resolved within the hour upon arrival of company employees. A lot of public transport apps have public transport maps of Montpellier's system. All 4 lines have a stop near the Montpellier train station which is convenient. Because we stayed 1 night in Montpellier, we bought a one-day pass (4.30 Euro per person) that we bought the first evening and it would expire a few hours after our train back to Nice. But for 8.60, we really made use of the trams taking at least 3 of the lines to both termini and back. The colors of the different tram lines on the outside and the inside is very appealing and they are very colorful. Also, you can use the tickets for any of the other services they operate besides tram such as the bus system. So it's really a value deal in the perspective of a tourist. You can't go wrong with affordable transportation, a smooth service, multiple lines, and more!!
