Yes, Brussels is considered a very walkable city, especially within the historic city center known as the "Pentagon." Most of the major tourist attractions, such as the Grand Place, the Manneken Pis, and the Royal Gallery of Saint-Hubert, are located within a compact area that can be easily navigated on foot. Walking from the Grand Place to the famous Sablon district or the Mont des Arts takes less than 15 minutes. The city has also significantly expanded its pedestrian zones in recent years, making the central shopping streets like Rue Neuve much safer and more pleasant for strollers. However, for attractions located further out, such as the Atomium or the European Parliament district, you will likely want to use the city's efficient metro or tram system. While the city is hilly in certain areas (the "Upper Town" versus "Lower Town"), the architectural variety and hidden comic-strip murals make walking the preferred method for tourists to truly discover the charm of the Belgian capital.
