This place is unmissable for those who feel at home in the water. It doesn’t matter if the sun is shining or it’s raining, if you’re young or in your prime, if you want to relax or to burn calories, if you come alone or with the family, or whatever the case may be, there is something for everyone in this water paradise.

Many, varied pools

Inside the complex, you will find a recreation area. There is a hot water lagoon, (the best for relaxing thanks to the hydro-massaging jets), a rapid river (let yourself be carried along by the current for some surprising sensations) and of course, the paddling pool. Your little angels won’t know which way to look among all the colourful animals spitting water as well as the waterslides. Let’s not forget Lud’eau the dragon who’s keeping an eye on all the nice people.
Something new: two giant waterslides have come to enhance the recreation area: Sismo, test it with a lifebuoy, with a friend or by yourself, and Volcano, without the lifebuoy this time but with more speed!
There is also a more traditional area with two pools. One has 8 lanes of 25 metres, ideal for doing a few lengths or following a swimming class. Note that on Sunday afternoons (as well as Monday to Friday afternoons during the school holidays), an obstacle course is set up to defy the more daring among you. Here, agility, balance and speed will determine your success.
Next to the large pool there is a small one with a special feature: a mobile bottom that allows a variable depth of between 0 and 2 metres. This is very useful for taking the first steps in the water (from 6 months, your baby will be able to participate in the swimming academy and follow practice and flotation sessions) or join in aquasport (aquafitness, aquabike, aquajogging, abs/butt). It’s good for the health, respects the body and is rewarding for the figure.
Friday evenings are diving evenings. La Royale ASM Plongée, a scuba diving school with different specialities (snorkelling, bottle, for children or athletes), will be happy to welcome you. Here, leisure and enjoyment go together! Beginners or experienced divers, welcome! You will follow theoretical and practical training, in a swimming pool and in a natural setting, with the goal of obtaining your diving certificate, which is internationally recognised. Following this, you will be able to dive around the world! In addition, every year trainee courses are organised that give you the opportunity to travel together to explore the seas near or far (from the Mediterranean to the Indian Ocean). Also, trips of one or several days are regularly organised in the nearby maritime regions and every Sunday, dives are organised in the quarries for club members.
Outside of the complex you will see a small paddling pool and another swimming pool. But outside there is absolutely no training. We’re here to enjoy the nice weather and to have fun!

A wellness area for stress relief

Come and enjoy the various facilities of this centre, the benefits of which do not need to be explained! Immerse yourself in a Jacuzzi, there’s nothing like it to reduce stress and help you sleep. Relax in the sauna (bio sauna at 70° C and Finnish sauna at 90° C), same effect as the Jacuzzi but with body detox and weight loss as a plus! Before the session, go through the foot bath. A foot bath will reinforce the benefits of the sauna. Go through it again afterwards to eliminate any residual heat.
Or, cleanse your skin in the hammam, ideal for cell renewal and clearing the respiratory tracts. Lastly, you can also go to the rest area and enjoy the relaxation room with deckchairs and tables at your disposal.

A restaurant area open to all

The Rest-eau-café, a meaningful name. Indeed, whether you want to get a drink or have a meal, whether you’re in a swimming costume or dressed, this brasserie will welcome you with open arms!

As for the swimmers, there is a terrace reserved just for you. It’s so nice not to have to worry about bringing a picnic on your aquatic day out!

For non-swimmers, the brasserie also has a large outdoor terrace with a secure playground for the kids. This is perfect for discovering the chef’s selection at a good price, while admiring the view over the Grand Large.

A centre that is accessible to all

We don’t leave things to luck here. We have thought of everything to make this site accessible to all: a lift, wheelchairs, sloped surfaces, adapted cabins and toilets, and a bath lift with access to the pool. A special price is also offered to persons with reduced mobility.

For all occasions!

Would you like to have a party in the water? An original idea and certainly a lot of fun! Lago offers various packages with access to activities and an adapted menu.
