The River Seine, winding through the heart of Paris, is transforming into a vibrant recreational hub, reminiscent of the French Riviera. Once plagued by concerns over hygiene, significant efforts in recent years have led to a notable improvement in the river's water quality, paving the way for Parisians and visitors to enjoy its banks for relaxation and even swimming.

This summer, the Seine has welcomed a series of chic establishments that enhance its appeal as a waterside destination. Annette K, a premium barge moored on the Seine at Port de Javel Bas, has become a popular spot since its opening three years ago. The venue features a 50-meter outdoor swimming pool, a spa, an open-air cafe, and a solarium, offering views of the city.

Cécile Favreau, a local hairdresser, described Annette K as "like a beach club" and "so peaceful." Access to the deckchairs at Annette K costs €10 for one hour and 30 minutes, with pool entry priced at €32. A monthly membership is available for €200. A spokesperson for Annette K stated they offer "something much more varied with sport, healthcare and a festive place."

This contrasts with Paris Plages, the city's free annual summer event that creates temporary beaches along the Seine, Bassin de la Villette, and Canal Saint-Martin, offering swimming pools, deckchairs, and cabanas.

For those seeking a more exclusive experience, other venues have emerged along the Seine. Polpo Plage, a seasonal extension of the seafood restaurant Polpo Brasserie, offers a beach club atmosphere in Levallois-Perret, away from the coast. Visitors can enjoy cocktails, waffles, and seating on a sandy area by the river. The venue transforms into Polpo Nord, a winter terrace, during the off-season.

Another establishment, Cozy, located near the Pont Alexandre III, describes itself as an "intimate and exclusive Parisian rooftop." It provides a space for guests to enjoy DJ sets, sunbathe, and have drinks by the water.

In addition to these establishments, permit-free boats are available for hire, allowing people to cruise along the water. These developments mark a significant shift for the Seine, moving it from a waterway once considered dirty and grimy to a desirable destination for leisure and recreation.
