Imagine lounging beside a swimming pool that stretches as far as the eye can see, with crystal-clear turquoise waters that rival the beauty of the Caribbean Sea. This is the breathtaking reality at San Alfonso del Mar in Algarrobo, Chile, home to the largest swimming pool in the world. This engineering marvel not only offers a unique recreational experience but also stands as a testament to human ingenuity and ambition.

A Record-Breaking Pool

1. World's Largest:

   • San Alfonso del Mar’s pool holds the Guinness World Record for the largest swimming pool by area. Covering an impressive 20 acres (8 hectares), the pool is a colossal 3,323 feet (1,013 meters) long, making it nearly 20 times longer than an Olympic-sized swimming pool.
   • The pool contains an astonishing 66 million gallons (250,000 cubic meters) of seawater, enough to fill about 6,000 standard backyard pools.

2. Crystal Clear Waters:

   • The pool’s water is sourced directly from the Pacific Ocean, which is just steps away. Advanced technology is used to filter and purify the water, ensuring it remains crystal clear and inviting.
   • The water is maintained at a warm and comfortable 26 degrees Celsius (79 degrees Fahrenheit) during the summer, which is about nine degrees warmer than the adjacent ocean.

Engineering Feat

1. Innovative Technology:

   • The pool was developed by Crystal Lagoons, a company specializing in large-scale artificial lagoons. They employed a cutting-edge technology that allows the pool to be filled and maintained with a minimal environmental footprint.
   • The water filtration system uses a small amount of additives and energy compared to traditional pool systems, making it more sustainable and cost-effective.

2. Construction and Maintenance:

   • Constructing such a massive pool was no small feat. It took nearly five years and an investment of around $2 billion USD to complete. The result is a stunning, lagoon-like pool that seamlessly blends with the surrounding natural beauty.
   • The maintenance of the pool is similarly impressive. It uses a fraction of the energy and chemicals typically required for pools, thanks to its innovative filtration and cleaning systems.

A Unique Recreational Destination

1. Resort Amenities:

   • San Alfonso del Mar is more than just its gigantic pool. The resort offers a wide range of amenities, including luxurious accommodations, restaurants, bars, and recreational facilities.
