Best Waterparks in London: Top Family Fun & Local Hidden Gems (2025 Edition)

Located just outside London in Surrey, Thorpe Lakes Aqua Park isn’t your average waterpark. As soon as I arrived, the expansive lake surrounded by lush greenery took my breath away. It’s a modular water wonderland filled with activities designed for thrill-seekers and families alike.

Why Thorpe Lakes Aqua Park Stands Out:

• Modular Course: The floating obstacle course here is nothing short of extraordinary. From giant slides to balancing beams, it’s like a Ninja Warrior course on water.
• Wakeboarding: For those who crave adrenaline, the park offers wakeboarding lessons. I dared to try it and, although I fell numerous times, the rush was unparalleled.
• Family-Friendly: Families are a common sight here. They offer life jackets and safety briefings, making it a secure, enjoyable experience for all ages.
