Make a Splash at Mersea Water Park
Mersea Water Park (formerly Mersea Boating Lake) is a 6-acre saltwater lake by the sea — a family-friendly hub where clubs gather, friendships grow, and everyone can enjoy watersports like paddleboarding, kayaking, and sailing. From open water swimming to the inflatable Aqua Park, there’s something for all ages to enjoy together.

Owner Manager
Hello! I’m Rebecca Edwards — and I’m so proud to welcome you to Mersea Water Park.

Some of you might remember me from my time managing the site back when it was known as Mersea Boating Lake. In November 2024, I took the leap and became the new owner, driven by a deep love for this place, paddleboarding, and all things outdoors. When we reopened in May 2025, my goal was simple: to keep the vibe alive.
I wanted to preserve everything that made the lake special while adding a fresh burst of energy and community spirit. Whether you’re here for a peaceful paddle, a family day out, or just to soak up the atmosphere, I hope you feel right at home.
