Luxembourg's swimming pools, from the slides at Strassen to the Olympic pool in Kirchberg

For a country of 2,586 km², Luxembourg has a surprising number of pools. The official tourism website lists 37 pools and bathing centres, from school pools that open to the public for a few hours a week to 10,000 m² complexes with waves, slides and saunas. If you’re travelling with children, or just need a wet-weather plan, the question is which ones are worth the trip. Below is my shortlist, plan by plan, with hours and prices as published in the week I looked them up.

The big water parks

Les Thermes in Strassen, on the edge of the capital, is the most complete for a full day in the water. There’s a 25-metre, six-lane pool at 28°C, a learner pool, a paddling pool, a wave pool and an outdoor pool at 31°C, a giant 80-metre slide from age 6, a fast 30-metre one from 12 and the Space-Shuttle, three 70-metre slides. On top of that come 6 saunas and 2 steam rooms. What I like most is that you pay by time, from €7 for 90 minutes to €18 for the day for an adult in September 2026.

Aquasud at Oberkorn, in Differdange, plays in the same league, with 10,000 m², six indoor pools including a 25-metre one, and play and paddling areas. The spa and gym are for over-18s, with five saunas, two of them outdoors, a steam room, a cold plunge and a jacuzzi, and there are 520 parking spaces. One warning, though. Its outdoor pool was closed for renovation and expansion, although the indoor side is open all year.

Worth leaving the city for?

That depends on where you’re staying. Syrdall Schwemm in Niederanven is close to the airport, and for a quiet afternoon it gets my vote. It has a huge glass frontage with views, a lawn and outdoor play area in summer, two Finnish saunas, a bio sauna and a steam room, and in that same week it opened 7:00 to 22:00 Tuesday to Friday. Up north, AquaNat’Our in Hosingen covers more than 3,500 m² with a children’s pool, saunas and a gym, and it was open every day until 21:30.

In the south, An der Schwemm at Bettembourg has the Black Hole, a 40-metre slide with sound effects and LED strobes, a waterfall and a paddling pool with a mini slide, and an adult ticket cost €5 for 90 minutes. The Escher Schwemm, beside Park Laval, is a 5 to 10 minute walk from the centre of Esch-sur-Alzette. And just north of the capital, visitguttland lists the PIDAL pool in Walferdange, with saunas, a spa and a restaurant.

Lane swimming in Luxembourg City

For proper swimming, head to the Coque in Kirchberg. Its Olympic pool opened in 1982 beneath a shell-shaped concrete roof by Roger Taillibert, who extended it in 2002 to create the National Sports and Cultural Centre. Its published hours on 30 September 2026 were 6:30 to 22:00 Monday to Friday, and it runs aquafitness classes.

The neighbourhood pools are more modest. Bonnevoie has a main pool with an adjustable floor from 1.80 to 3.80 metres, a smaller pool, a sweat bath and a solarium, and closes on Wednesdays. Cents, 25 by 15 metres, lets the general public in only at weekends (Saturday afternoons until 20:00 and Sunday mornings), and Belair is for schools and clubs only. The Badanstalt in the centre has a pool with water jets, two saunas and a Turkish bath, but its listing had it shut on all seven days from 30 September to 6 October 2026, with no reason given. I’d phone first.

The summer lidos

Between May and September the tourist board recommends the outdoor pools at Remich, Wiltz and Beaufort, and I’d add Vianden for the view. It’s heated, with a slide 6.5 metres high and 65 metres long and a refreshment bar looking up at the castle. Remich’s heated pool by the Moselle opened from 15 May to 15 September in 2025, 10:00 to 19:00. The Kaul in Wiltz opens daily from mid-June to mid-September, and Beaufort’s Aqua Park, with a 50-metre slide, from mid-May to early September.

There are others. Troisvierges has a 45-metre slide and a current channel, Grevenmacher charged adults €10 for the day and Rosport, at the Camping du Barrage, €5. They’re seasonal and their published dates end in September, so from October I’d count on indoor pools until they reopen in May or June 2027.

Thermal baths, spa hotels and lakes

None of these has thermal water. The country’s only thermal pool is at Mondorf Domaine Thermal, at 36°C, and its prices and house rules are in my guide to Mondorf spa. For a hotel with its own pool and saunas, my list is in spa hotels in Luxembourg. The four lakes with monitored zones are the other summer option, since the bathing season opens on 1 May and closes on 30 September (the 2026 one is over). I cover them in swimming lakes in Luxembourg.

How I’d fit a pool into a trip

With children on a rainy day, Les Thermes in the morning on a four-hour ticket. With the LuxembourgPass, I’d use it at AquaNat’Our or Bettembourg, which are free. And if you swim every day at home, the Coque first thing, before you start on the city.

If you are short on time, see the best tours in Luxemburgo and pick one that fits your day.

Where the bus does not go, a car does: compare car hire in Luxembourg before you arrive rather than at the desk.
