Aqua Adventure is a water park located in Central Park of Fremont, California.

Currently, there are two open and two enclosed slides that twist and turn from a height of 40 feet above pools and slide-stopping water gates called run-outs. A 700 square-foot, three foot deep lazy river surrounds much of the complex while a splash zone of water features water jets and sprays.

In addition, a 25-yard "utility pool" with five lanes will provide a swimming and exercise venue. For younger guests, a zero depth entry to the water course and a water bucket spray area has a depth of only one foot of water. Fremont Director of Parks and Recreation, Annabell Holland noted, "The deepest section of the entire park is four feet in the middle of the utility (lap) pool." Twelve shade structures will provide relief from the sun on hot days.

While at the park, Locker rooms, concession stands, food service, picnic areas, offices and other park amenities are available for use.

In 2001, the City Council approved a project to utilize the site of the Puerto Penasco Swim Lagoon into a modern, family-oriented water play facility that would serve both the residents of Fremont as well as the surrounding region. The Family Water Play Facility (also known as the "Water Park") was proposed to be developed on approximately four of the seven acres of the site, which had provided water-oriented recreation to the citizens of Fremont for 32 years prior to closing in 2001. The Water Park would be designed to provide a wide range of interactive water-based activities and experiences, for people of all ages, and would be focused on family fun. In addition to the many water-oriented activities, the design would provide picnic areas for small and large groups wishing to enjoy celebrations of family events; company get-togethers; and similar activities.

Construction was completed in early 2009 and was open to the general public on the Memorial Day weekend in May 2009.

Guests will not be allowed to bring food into the park, but food service is planned within, and there is a grilling area. Wristbands will facilitate multiple entries such that entrance and re-entrance can be permitted. Birthday parties will be welcome at Aqua Adventure and may reserve a shade area to congregate. Groups that would like to reserve Aqua Adventure for private functions will have an opportunity to do so after hours. Since the park is scheduled to close late afternoon, private functions may become a popular use of the facility. "We have two group areas that can be used for such parties," said Holland. Pricing is still being discussed. In October, the Recreation Commission will submit a recommendation.

Although there is additional acreage at the site for possible expansion (approximately four of 7 acres (28,000 m2) is being developed), Holland said, "I am very protective of this as a family-oriented water park." She said there is a possibility of adding other features within that theme if the numbers justify it. In ground capacity of Aqua Adventure - the number of people that be accommodated at any point in time is approximately 1,200 people. It is projected that the crowd will change about two times each day.
