When discussing the largest swimming pools on the planet, we’re certainly not talking about your average-sized watering hole.

While there have been large man-made pools practically since civilization began, these swimming pools in particular defy the imagination in terms of their sheer scale.

You may have visited a few resorts in your time with large luxurious over-the-top pools, but trust me when we say that those pools are practically teacup-sized in comparison to these swimming pools. We’ve covered plenty of swimming pool Top 10’s in Pool Magazine, including the world’s most expensive pools. Today, however, we’re going to be looking at some of the largest pools on Earth. With that said, let’s dive right in!

Statistics are all well and good, but we’re dying to know more about these massive swimming pools and we’re sure you are too. Let’s take a closer look at each one of the swimming pools on our Top 10 Largest Swimming Pools list.

In conclusion:

You may have asked the question “what is the largest swimming pool in the world” and gotten 100 different answers. Unfortunately, there is a lot of conflicting information out there and statistics have a tendency to be copied & pasted without much fact-checking these days. Stats also have a way of changing quicker than human beings tend to update their websites.

In fact, the Guinness Book of World Records even still lists the 8.9-acre Orthlieb Pool in Casablanca, Morocco as the largest pool on the planet. Unfortunately, that pool was demolished back in 1986 and hasn’t been around for quite some time. There are also plenty of places that still list the San Alfonso Del Mar as the world’s largest swimming pool, but it was supplanted back in 2015 by the #1 pool on our list. City Stars Sharm El Sheikh is officially the largest swimming pool on the planet – for now.
