August rewards visitors who prefer a slower pace: the old town is easier to enjoy without the June crowds, and it's a great time for an unhurried day trip to Giverny, where the water garden is lush with late-summer blooms. Evening visits to the Cathédrale de Lumière are especially pleasant with the warm night air.
