Keep Smiling opens the gateway to a beautiful underwater world. The diving centre has a large Underwater Park in the ‘Surfplas’. The park consists of a platform with Christmas trees, a wreck, a slide, the top of a lifeboat and the cherry on the cake: a real city bus! Anyone with a diving license is allowed to enjoy the Underwater Park. You do however have to request permission in advance. A tire and line track runs underwater from the diving jetty (also suitable for the disabled) to the large hardwood platform. From this platform, you can follow a line that runs past all the diving objects. A sign at the diving jetty explains everything you need to know. If you scan the QR code there, you will be able to go directly to the website of the diving centre .
