Introduction to the World’s Biggest Pool in Chile
The world’s biggest pool in Chile is the San Alfonso del Mar resort pool near Algarrobo, on the central coast. Completed in 2006, it holds approximately 250 million liters of seawater and spans about 1,013 meters in length. The pool is a saltwater lagoon maintained by wave-driven pumps and filtration systems. It is recognized by Guinness World Records as the largest outdoor pool. This overview provides verified attributes, context, and practical details for long-term reference.

Context and Purpose
The pool was created primarily for resort swimming and tourism, providing a vast, sheltered lagoon experience. Its design uses natural seawater and a system that harnesses wave energy for circulation and filtration. The pool supports the resort’s broader offerings, including beaches, sailing, and events. It functions as a landmark example of large-scale recreational engineering in a region known for dry climates and coastal geography.
Engineering and Maintenance
The pool’s size required sophisticated water management. Engineers use pumps that draw in ocean water and maintain quality through filtration and controlled circulation. The lagoon’s shallow average depth reduces construction and energy costs while still delivering a spacious swim area. Ongoing maintenance focuses on water clarity, salinity balance, and structural integrity of containment berms and barriers. These systems ensure the pool remains safe and usable year-round.
Key Engineering Points
- Wave-driven pumps help move and oxygenate water.
- Shallow average depth eresses thermal stability and maintenance.
- Containment structures manage tides and surges.
- Filtration systems handle large volumes continuously.
Practical Visitor Information
The pool is part of the San Alfonso del Mar resort, which offers lodging, dining, and water activities. Access is typically through resort packages or day-use options depending on availability. Visitors can swim in the pool and enjoy nearby coastal experiences. Planning ahead is recommended due to limited public access and the resort’s booking requirements.
- Check resort websites for current entry policies and pricing.
- Consider seasonal weather patterns; summers are popular.
- Book accommodations or day passes in advance.
- Prepare for sun protection and bring necessary gear.
Comparison to Other Large Pools
When compared to other massive pools worldwide, San Alfonso del Mar stands out for its outdoor setting and Guinness-certified size. Indoor pools and aquatic centers may hold more water, but this pool’s surface area and open-air environment are distinctive. Its location in a desert coast adds to its uniqueness as a tourism anchor.
