Are you a fan of doing laps? How about in a swimming pool that is over 1,000 yards long and covers 20 acres? Still interested? An Olympic size pool is about 50 yards by 25 yards so this pool is slightly larger. Check out the picture below of the largest pool in the world according to the Guinness Book of Records. The pool lies right next to the sea in Chile and is filled with over 66 million gallons of saltwater.
Chile has the world record for the largest outdoor swimming pool. Watch this Reuters video showing how this massive pool recycles seawater to keep it clean. The pool is well over half a mile long and more than 90 feet deep in places.
