San Alfonso del Mar, Chile

The world's largest hotel swimming pool is located along the coastline of Chile. San Alfonso del Mar is a resort in the South American nation's Central Coast region. Its massive pool covers nearly 20 acres and stretches for more than half a mile. For a little perspective, you could pour the water from several thousand standard 25-foot hotel swimming pools into San Alfonso and still not fill it up.

The pool is more than 100 feet deep in some sections. The water that fills it (more than 66 million gallons in total) is pumped in from the nearby Pacific Ocean. It is filtered and treated before reaching the pool. Hundreds of hotel rooms and rental apartments sit right next to this human-made swimmer's paradise.
