Most visitors spend between 5 and 7 hours at Aquapark El Arenal. This allows enough time to enjoy the main slides, take breaks, and explore family-friendly areas without rushing. A shorter 3 to 4-hour visit is possible if you focus only on the highlights, but queues may limit how much you can experience.
However, your entry tickets get you a 1-day pass, which means you can enter the park at 10am and stay until the rides close 15 minutes before closing time.
