When the thermometer goes wild, there’s only one impulse: find a splash of cool water without necessarily heading to the sea. Good news, swimming is the standout activity of the bathing during the summer holidays, and Seine-Saint-Denis (93) has nothing to envy its Île-de-France neighbors on this front. From ephemeral urban beaches to mega leisure hubs, via the inflatable courses and other outdoor pools, the department is rolling out a lovely lineup of spots to cool off this summer 2026, most often free and a stone’s throw from public transport. We’ve marked out for you the addresses where you can lay down your towel.

The department thus steps into the realm of nature-filled sites, long limited to the Marne on the Val-de-Marne side. And for those who prefer sand and water games, the 93’s ephemeral beaches will be taking over throughout the summer.
From ephemeral basins to the The Canal Summer, ephemeral urban beaches with pools and toddler pools, there’s plenty to choose from… And what if we went for a dip in Seine-Saint-Denis?
