While The Plunge has a fresh new look, it has a rich history. The Natatorium, which later became known as The Plunge swimming pool was constructed in 1925 as a centerpiece of the park along with the Giant Dipper Roller Coaster within the original Mission Beach Entertainment Center, now known as Belmont Park. The 60’ by 175’ pool was, at the time, the largest salt-water pool in the world— holding 400,000 gallons of water. The building encapsulating The Natatorium was styled after the Spanish Renaissance style buildings that were erected in San Diego’s Balboa Park between 1915 and 1916. In 1940, the saltwater of The Plunge began to damage its filtration system and freshwater was brought in to the pool. The Plunge then became “the largest indoor heated pool in Southern California,” at 12,000 square feet. It was previously connected to Wavehouse Athletic Club, as a feature of the gym open to the public. Years later, the pool has been transformed into a new and modernized experience within Belmont Park and reopened its doors as The Plunge San Diego. The fresh look offers an upscale experience for all ages.
