Grenoble sits in the Isère River valley, surrounded by three mountain ranges in the French Alps. The city combines alpine landscape with urban infrastructure and serves as a base for exploring the surrounding mountain regions. The Fort de la Bastille, accessible via a historic cable car, provides views over the city and valleys. Parc Paul Mistral covers 52 acres (21 hectares) in the city center and includes sports facilities and green spaces. The Musée de Grenoble displays European artworks from the 13th century to the present, including French painting and modern art. The Musée Dauphinois documents regional history and alpine culture. The Musée de l'Ancien Évêché focuses on local history from the Middle Ages to the present. Place Saint-André forms the historic center with medieval architecture, while Place Grenette serves as a central market square. Château de Vizille, located 9 miles (15 kilometers) south, was the site of the 1788 assembly and now houses a museum on the French Revolution. The Grottes de Sassenage, prehistoric limestone caves on the city outskirts, offer guided tours through underground galleries.
