The historic birthplace of Paris, Île de la Cité holds some of the capital's most storied monuments, before giving way to the far quieter atmosphere of neighboring Île Saint-Louis. This itinerary follows the two islands from east to west, from Notre-Dame to the 17th-century townhouses beyond, for a walk of roughly two hours along the Seine.
Notre-Dame de Paris, the starting point
Reopened to the public in December 2024 after the 2019 fire and years of restoration, the cathedral has recovered its Gothic facade, its twin towers and its rose windows. Take a moment to admire the square in front before going in, since it is from there that the scale of the building is easiest to appreciate.
Sainte-Chapelle, a masterpiece of stained glass
Built in the 13th century by Louis IX to house the Crown of Thorns and other relics of the Passion, this royal chapel's upper level holds fifteen stained-glass windows over fifteen meters tall, telling biblical stories in colored light. On a sunny day, the light pouring through makes it one of the most striking interiors in Paris.
The Conciergerie, from royal palace to prison
Once a residence of the kings of France before they moved to the Louvre, this vast medieval complex became a feared prison during the Revolution, where Marie-Antoinette was held before her execution. The Salle des Gens d'Armes, a huge vaulted Gothic hall dating to the 14th century, hints at the scale of the original medieval palace.
Pont Neuf, Paris's oldest surviving bridge despite its name
Completed in the very early 17th century under Henri IV, it remains, despite its name meaning "new bridge," the oldest bridge still standing in the capital. It spans the western tip of Île de la Cité and offers one of the finest views over the Seine and its quays.
The townhouses of Île Saint-Louis
Crossing over to Île Saint-Louis, the contrast is immediate: fewer grand monuments, but rows of 17th-century townhouses along narrow streets, dating from when the island was developed all at once. Rue Saint-Louis-en-l'Île, its main street, still feels like a small village today.
Quai d'Orléans, river views
This quiet riverbank, lined with elegant facades and benches, offers one of the best views back toward Île de la Cité and the rear of Notre-Dame. It is one of the calmest spots in central Paris to stop for a few minutes by the water.
Berthillon, the finishing point
Founded in 1954 on Rue Saint-Louis-en-l'Île, this shop has become a Parisian institution for its handmade ice creams and sorbets, with flavors that change with the seasons. It makes a fitting end to the walk, whatever the time of year.
Tips
Start at Cité metro station (line 4) or Saint-Michel Notre-Dame, on the square in front of Notre-Dame. From there, head to Sainte-Chapelle and the Conciergerie, both within the grounds of the former royal Palais de la Cité, before crossing to the western tip of the island to reach the Pont Neuf. Cross the Pont Saint-Louis to reach Île Saint-Louis, walk down Rue Saint-Louis-en-l'Île to Quai d'Orléans, and finish at Berthillon. Allow for about two kilometers and an hour and a half to two hours of walking, including visits. Book a time slot in advance for Sainte-Chapelle if you can, to avoid the line, especially in high season, and aim for a morning visit for softer light on the stained glass. If the line at Berthillon's original shop is too long, several cafés and brasseries on Rue Saint-Louis-en-l'Île serve the same ice cream under license.
