When the sun sets, Mont Saint-Michel transforms into a magical scene with precise architectural lighting highlighting the abbey, church, and walls. The illumination begins at dusk and continues throughout the night, free for everyone. Best viewing points are from the bridge (Pont-Passerelle), the new dam, and the sand beach at low tide. Staying overnight on the island offers a unique experience when tourists leave and the magical atmosphere returns. The sunset behind the island is particularly stunning.
