Aquaboulevard is Europe’s largest urban water park, located in the 15th arrondissement of Paris at 4‑6 Rue Louis Armand. It covers about 7,000 m² and includes indoor and outdoor pools, wave pools, multiple giant slides, rivers with counter‑current flow, jacuzzis, geysers, water play structures, and a sandy beach area of several thousand square metres with beach huts. For relaxation there are also wellness features like saunas, hammams, and hot tubs. It forms part of a larger leisure complex that includes fitness, cinemas, restaurants and shops.

Children must be at least 3 years old to enter. Children aged 3–11 get a child rate, and those under 12 must be accompanied by an adult. For safety and hygiene, armbands are compulsory (free for kids up to about 6 years old), proper swimwear (tight‑fitting trunks or speedo-style for men) is required, and showers and foot baths are mandatory before entering pools. Picnics and street clothes are not allowed in the pool areas. Outdoor slides or areas may be closed during colder or off-season periods.

Entry prices are around €39 for adults (12 years and older) and about €21–22 for children ages 3–11. Those under 3 years are not allowed in. There are often reduced or cheaper rates for entry after 5 pm, and family tickets or offers are available. The park typically opens early (around 8–9 am depending on the day) and closes in the evening (often 11 pm or midnight on weekends). Arriving about 30 minutes before closing is not advised if you want full use of the facilities. It’s smart to check opening hours and availability of outdoor areas or slides before your visit.
