Montmartre, a historic hilltop neighborhood in Paris, is famous for the Sacré-Cœur Basilica, Place du Tertre (where artists create and sell their work), and its charming, winding streets. While generally accessible, the steep inclines can pose challenges for those with mobility issues; consider the funicular to reach the basilica. Montmartre is enjoyable both solo and with guided tours, with the latter offering deeper insights into its history and artistic legacy. The area is open year-round, but the atmosphere is particularly vibrant in spring and fall. Budget varies greatly depending on dining and shopping choices, but expect to spend at least €50-€100 per person. A typical visit lasts 3-5 hours, but allow more time if you plan to explore extensively or visit museums.
