In fact, I live in Montpellier. What Christine wrote is right on but I would say that you don't have to go as far as Marseille to see some beautiful things. Languedoc Roussillon, the region where Montpellier is located, has mountain ranges as well as the beach so its a great place for hiking and biking. It's also a wine producing region so there are always opportunities for wine tasting. There are quaint towns surrounding Montpellier such as Pezanas, Sete and St Guilhem le Dessert as well as the famous little city of Nimes. All of these locations are less than an hour away from the city and are beautiful.
While there are not many monuments to visit, as it's a big university town, there are always festivals and other activities that keep the locals entertained. Its a good liveable city with super friendly folks.
