A companion guide for the Latin Quarter after Notre-Dame, with bookish streets, churches, cafés, and river crossings.

Cross from Île de la Cité toward the Latin Quarter and let the bookshops, Shakespeare and Company, and narrow streets set a slower pace right after Notre-Dame.
The Panthéon, the Cluny medieval museum, or Saint-Étienne-du-Mont gives the wander a focal point. Pick one rather than trying to see all of them.
The Luxembourg Gardens edge or a classic café closes the loop well and connects easily onward to Saint-Germain or back across the Seine.
