Hobby diver

As a hobby diver, you should already be a “Open Water Diver”

Have you already attained your diving licence and can proudly call yourself “Open Water Diver” (or equivalent)?

Then you can also use our facilities without a diving instructor, because we can assume that you have already gained the required and safety-relevant skills.

Nevertheless, you should have a diving partner with you! It’s more fun in pairs anyway!

If you don’t have a diving buddy, you can book a diving companion from us for €35 per hour plus admission fee and equipment.

As breaks at surface level are necessary between multiple dives and diving makes you feel hungry, you can have a meal in the neighbouring restaurant or eat your own food in the common area. Please note that glass and porcelain are strictly prohibited for safety reasons.


20 metres deep, 18/10 metres in diameter and more than three million litres of crystal clear water – these dimensions are breathtaking, even for experienced divers. The dive4life indoor diving centre in Siegburg near Cologne/Bonn is the biggest complex of its kind in Europe.

Diving experience

Adventure diving: Beginners and professionals can look forward to a variety of diving experiences in the indoor underwater world, e.g. in the sunken city: Here, you can quietly dive through remarkably realistic ruins and plateaus at different depths!


Whether you need a full set of equipment or individual components, such as a diving suit, diving jacket, regulator, diving computer, flippers or mask – you can rent any kind of diving equipment from us at a fair price.

A compressed air cylinder and lead are included in the admission fee!

In addition to the rental of equipment, we also offer a diving shop as well as a repair shop for repairs and maintenance work. We will happily assist you with the equipment check and will provide you with individual and competent advice on all relevant diving topics!
