This dive site is Nemo 33 in Brussels, Belgium, an iconic indoor diving facility once renowned as the world's deepest swimming pool. It offers a unique controlled environment for divers of all levels, featuring multiple platforms at depths of 1.5, 3, 5, 10, and famously descending to 33 meters (though the maximum depth for typical recreational diving discussed here is 20 meters). The pool contains 2.5 million liters of water, maintained at a very comfortable 33 degrees Celsius, providing an ideal setting for training and skill development. Its multi-level structure allows for progression and specific depth exercises, making it perfect for courses and practice.
As an artificial indoor facility, Nemo 33 does not host any natural marine animals or plant life. The focus here is entirely on diver training, equipment testing, and recreational diving in a pristine, controlled underwater environment free from natural ecosystems.
Nemo 33 is an indoor facility, making it suitable for diving year-round, regardless of external weather conditions. It is particularly ideal for divers seeking to learn new skills, complete certifications (from beginner to advanced and technical), refresh their abilities, or simply enjoy a warm, clear water dive. Freedivers will find it an excellent location for depth training. Tips include utilizing the various platforms for buoyancy practice and descent training, and enjoying the consistently warm water which often negates the need for thick wetsuits.
