Aqua Adventure, Water park in Central Park, Fremont, California, United States.

Aqua Adventure is a public water park in Fremont, California, with multiple pools, slides, spray features, and a lazy river for floating. The facility is laid out across a large open site and caters to swimmers of all ages and skill levels.

The site was the Puerto Penasco Swim Lagoon, which served Fremont for 32 years before closing in 2001. That year the City Council approved a family water play facility on about four of the seven acres. Construction finished in early 2009, and the park opened on Memorial Day weekend in May 2009.

Aqua Adventure runs swim lessons in two-week sessions, Monday through Thursday, mornings and evenings, plus Saturday morning classes and private lessons. Junior Lifeguard camps meet about three times each summer, a week long, covering CPR, rescue breathing, shallow-water rescues and first aid. Lap swim uses the Oasis Pool after the park closes on weekdays and on Saturday mornings.

The grounds have changing rooms, food vendors, and picnic areas, so a full day visit is easy to plan. On hot days, arriving early is a good idea since shaded spots tend to fill up quickly.

The Oasis Pool is a 25-yard, five-lane lap pool, and the zero-depth entry and water-bucket spray area are separate features with only one foot of water. Parks and Recreation Director Annabell Holland noted that the park's deepest point, four feet, is in the middle of this lap pool.
