A serene oasis dedicated to your well-being

Dear clients,

We are happy to announce the reopening of Martin'Spa & Fitness.

From September 6, the Spa area (treatments & massages) will be open every day from 10 a.m. to 6 p.m. On Tuesdays and Thursdays, however, certain treatments cannot be provided. We will tell you on a case-by-case basis.

The Thermal Baths (swimming pool & sauna) and the terrace are only reserved for Spa clients having treatment (s) and members of Fitness. Access is limited to 45 minutes per person. By reservation only.

The Fitness is also open from 7 a.m. to 9 p.m. on weekdays and from 9 a.m. to 7 p.m. on weekends.
Group lessons also resume and must be booked in advance.

In order for the experience to be reassuring for everyone, we must develop new habits during treatment and fitness sessions. We are counting on you to apply them and are at your entire disposal for any further information.

The Martin'Spa & Fitness team

Are you looking for a spa, wellness or fitness centre that’s easy to reach from either Brussels or Namur? While, of course, also meeting your high requirements concerning the quality of the facilities and the treatments. And your discernment for details that make the difference. 

Welcome to Martin'Spa – a modern spa where you can unwind completely, surrounded by the magnificent environment of the Martin's Château du Lac de Genval.

We invite you to visit our wellness centre for a rich array of relaxation sessions or stays, treatments and dynamic workouts. Compose the programme that suits you best. An hour of massage, or perhaps an extended relaxation with overnight stay? Or register for our fitness room.
