Geek Pool: Belgium's Nemo 33
This is the deepest indoor pool in the world. The Nemo 33 was constructed back in 2004 and if you’re from Belgium, you’ve probably enjoyed 30 degrees Celsius of spa water (it’s non-chlorinated!) all year round. At over 33 meters deep (that’s about a little bit more than a hundred feet) the pool caters to the public who want to get away from the winter cold and to divers and would-be divers who are taking their certification courses. At over a hundred feet deep, you can actually take your open water and advanced open water courses here as the pool will suffice for a deep dive.
Within the pool are several holes and tunnels which divers can explore all year round. No fish. If you’re ever planning on stopping by Belgium, do check this place out. The facility is huge, and it’s not just all pool. The place houses a bar and restaurant as well, turning it into a total recreation destination day and night.
The only thing I don’t like about the Nemo 33 is their really ugly website.
