If you want to see a show while you're in town, try and grab some tickets at Zenith de Toulouse in Toulouse Left Bank. If you enjoy the show and want to see another, Casino Theater Barriere of Toulouse, Halle aux Grains Theater, and Le Fil a Plomb are not far.
You can study the exhibits at Les Abattoirs, a museum with a story of its own, during your trip to Toulouse. Stroll along the riverfront or seek out the biking trails.
