Surprising Scuba Diving Hotspot: Brussels, Belgium
The 105-foot-deep Nemo 33 has a tropical feel with the water kept at 33 degrees Celsius (91 F). You can learn to SCUBA there or just enjoy your own dive while your non-diving friends sit in the restaurant and watch you descend into the human aquarium.
A safety warning: We recommend diving in Nemo 33 first, before consuming the required ton of Belgian chocolate. Eating the sweets first could lead to serious sinking problems.
