Indre-et-Loire IGN Top 100 Map | Tours, Chinon & Loire Valley Châteaux Road Map

Step into the "Garden of France" with the IGN Top 100 Indre-et-Loire Map. Part of the recently launched Top 100 Tourisme series (Map D37), this 1:100,000 scale map is the definitive guide for Department 37. Specifically updated in May 2025, this map is engineered for travelers who want to explore the majestic Loire Valley by car, bicycle, or on foot, offering a comprehensive view from the vibrant city of Tours to the medieval fortresses of Chinon and Loches.

This map is an essential companion for visiting the world-famous Châteaux of the Loire. It provides unrivaled detail of the Parc Naturel Régional (PNR) Loire-Anjou-Touraine and the scenic valley floors. Cyclists will find the entire La Loire à Vélo route and an enriched network of secondary roads vetted for safe travel in partnership with the AF3V. For hikers, the map features a high-visibility overprint of the GR® and GR de Pays® networks, including the GR 3 and GR 655 (Way of St. James). With contour lines for topographic clarity, a trilingual legend (French/English/German), and full GPS compatibility, this map ensures you won't miss a single vineyard, castle, or panoramic viewpoint in the Touraine region.
