Île-de-France is France's most populous and economically powerful region, home to Paris and an extraordinary concentration of world-class museums, châteaux, gardens, and culinary experiences. Surrounding the French capital, the region stretches across the Seine and Marne river valleys, encompassing the palaces of Versailles and Fontainebleau, the medieval streets of Provins, and vast forests perfect for cycling and hiking.

Beach safety
Hard-earned guidance — read this before you swim, especially if you’re unfamiliar with the coast.
Critical
Swim where lifeguards are posted and follow flag warnings — green is safe, yellow is caution, red means no swimming. Rip currents are the leading beach hazard worldwide.
Caution
Watch for tide changes and marine life — jellyfish blooms, sea urchins on rocky entries, occasional shark or stingray advisories. Don’t swim alone, especially at dawn or dusk.
Tip
Reapply sunscreen every 90 minutes and after every swim. Take shade between 11 am and 3 pm — the sun is harsher than people expect, even when the air is cool.
Practical
Keep valuables out of sight or back at the accommodation. Beach theft is a small-but-real risk at busy beaches; never leave bags unattended while you’re in the water.
