If you’re someone who suffers from thalassophobia or the fear of being in deep water, you will most definitely stay away from the ocean and deep-sea diving. <\/p>\n\n\n\n

However, did you know that some massive swimming pools in the world appear to be almost as dark, deep, and unknown as the vast ocean? <\/p>\n\n\n\n

Whether you’re fascinated by the deepest pools the world has ever seen or an individual who wants to stay as far away as possible, you have to admit that the topic piques a bit of interest. We put together a list of some of the deepest pools in the world and where you can find them. We included the worlds’ deepest natural pools (#1: Great blue hole) and the worlds’ deepest swimming pools (#1: Blue Abyss) in our list of deepest pools in the world.<\/p>\n\n\n\n

The worlds’ 10 deepest pools<\/figcaption><\/figure>\n\n\n\n

Below are ten of the deepest swimming pools from all around the world, along with a bit of background information for each of them.<\/p>\n\n\n\n

10th Deepest Pool in the world: NASA Pool<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Ever wonder about how astronauts train? The NASA training pool<\/a> isn’t your average Olympic-sized pool. In fact, it’s much larger than that. <\/p>\n\n\n\n

Not only is the NASA training pool 202 feet long, but it sinks down to a depth of 40 feet (ca. 12 meters)<\/strong>, which is much deeper than average pools ranging anywhere from 8 to 12 feet. It holds a whopping 6.2 million gallons of water, which could fill about 10 Olympic swimming pools. <\/p>\n\n\n\n

The large pool certainly has specific purposes aside from a diver’s paradise. Underneath the water is actually pieces of the International Space Station. Using the buoyancy of the water paired with various weights and floatation devices, astronauts can practice their actions and simulate what it feels like to be in space with zero gravity. How cool is that?<\/p>\n\n\n\n

9th Deepest Pool in the world: Abyssea Diving Pool<\/h3>\n\n\n\n

Also located in France, the Abyssea diving pool is a part of an aquatic facility dedicated to fitness, well-being, relaxation, and overall fun. This popular tourist attraction features a 16-foot swimming pool with an attached diving pool that measures about 65 feet (ca. 20 m) <\/strong>deep. <\/p>\n\n\n\n

Here, beginners and experienced divers alike can swim down the deep depths for an ocean-like experience with the safety and security of professional equipment, trainers, and guides. <\/p>\n\n\n\n

Divers can also rent photography equipment, or professional underwater photographers<\/a> can work on honing their skills at the bottom of this deep pool.<\/p>\n\n\n\n

Windows allow loved ones and interested parties to watch the divers go all the way to the bottom, making for a well-rounded and thrilling experience in this facility.<\/p>\n\n\n\n

8th Deepest Pool in the world: Fosse of Villeneuve-la-Garenne <\/h3>\n\n\n\n

Fosse of Villeneuve-la-Garenne is a France-based indoor diving facility that offers a diving experience to over 40,000 divers every year. The pool boasts three different pits at about 16 feet (ca. 5 meters), 32 feet (ca. 10 meters), and 65 feet (ca. 20 meters) <\/strong>deep. <\/p>\n\n\n\n

The deepest of these three diving puts also hosts high-tech equipment, including a movable floor and a video camera for the best experience possible. Individuals can practice scuba diving and free diving with supervised practice sessions and underwater activities. <\/p>\n\n\n\n

Other programs include particular first aid training and even baptisms. Apnea and yoga courses focus on deep breathing, relaxation, and yoga to help build muscle and flexibility in a new and unique way.<\/p>\n\n\n\n

7th Deepest Pool in the world: Homestead Crater<\/h3>\n\n\n\n

While some of the world’s deepest swimming pools are entirely man-made, there are some swimming destinations that came about naturally. The Homestead Crater in Utah is one of them.<\/p>\n\n\n\n

The Homestead’s hot spring is a must-visit destination for scuba divers and enthusiasts from all over the world. It boasts a depth of 65 feet (ca. 20 meters)<\/strong> and a base that is 400 feet (ca. 122 m) wide. In fact, it is the only warm scuba destination in the Continental US where you can get certified in scuba diving.<\/p>\n\n\n\n

This crater is believed to have been created over a period of 10,000 years from the snow melting off of the Wasatch Mountains. Just two miles below the surface, the earth’s heat radiates to keep the water consistently warm between 90 and 96 degrees. <\/p>\n\n\n\n

These temperatures make this spot the only warm scuba diving location in the continental US, which makes it an excellent destination for dedicated divers. The 65-foot depth makes for a fun dive, and the 400-foot base leaves plenty of space for exploring.<\/p>\n\n\n\n

6th Deepest Pool in the world: Nemo 33<\/h3>\n\n\n\n

The Nemo 33 pool is a freshwater facility located in Belgium, specifically Brussels. The facility contains over two million liters of non-chlorinated water throughout several underwater caves, tunnels, and houses. However, the deepest point of Nemo 33<\/a> is the deep pit, which reaches down to 113 feet (ca. 34 meters).<\/strong> <\/p>\n\n\n\n

People use the facility for all kinds of diving, from tourists looking for some fun to professional divers honing their skills. Because the water is kept at a regulated, warm temperature, divers can actually swim down to the deepest depths without a wetsuit<\/a>. <\/p>\n\n\n\n

With the water and the deep pit being the main attractions, Nemo 33 also has a restaurant, a bookshop, and a souvenir store along with several underwater windows for viewing the various water activities.<\/p>\n\n\n\n

5th Deepest Pool in the world: TODI<\/h3>\n\n\n\n
\"TODI
The TODI pool is detailed nicely. You can even find a car wreck in this massive belgium indoor pool.<\/figcaption><\/figure>\n\n\n\n

TODI is another bottomless diving pool in Belgium, but this one has the unique attribute of doubling as a freshwater aquarium.<\/p>\n\n\n\n

The main pool in the facility measures 32 feet (ca. 10 meters) deep and 118 feet (ca. 36 meters)<\/strong> wide. With about 6.5 liters of water, this pool is undoubtedly larger and more profound than the swimming pool at your local rec center. <\/p>\n\n\n\n

What makes this deep pool exceptionally special is the thousands of colorful fish that accompany you underwater. <\/p>\n\n\n\n

This coal depot-turned dive facility lets divers swim down into temperature-controlled water and explore the sea without actually being in the ocean. The water is chock full of tons of freshwater fish<\/a> and beautiful ocean scenery for a once in a lifetime experience.<\/p>\n\n\n\n

4th Deepest Pool in the world: Y-40 Deep Joy<\/h3>\n\n\n\n

Located in Italy, the Y-40 Deep Joy pool was once the deepest indoor swimming pool in the world, with its deepest point reaching 130 feet (ca. 40 meters)<\/strong>. The gigantic pool goes as deep as a 14-story building is high, so it’s kind of a big deal. <\/p>\n\n\n\n

Like some of the other pools on our list, Y-40 features systemwide heating that keeps the pool at warm enough temperatures to eliminate the need for a wetsuit for divers. This particular deep pool is cylindrical and specially designed to hold 4,300 cubic meters of water.<\/p>\n\n\n\n

To dive to the bottom of this pool is scary as fuck. In this video, Guillaume N\u00e9ry explores the bottom of Y-40 without oxygen. When I watch this, I feel like dying 10 times over, when Guillaume jumps into the dark hole.<\/p>\n\n\n
