Cotswold Country Park and Beach is the number one attraction in The Cotswold Water Park. The Park is open year-round, and offers the largest inland beach in the UK, activities, boat and kayak hire, cafes and wonderful lakeside walks. Cotswold Country Park and Beach comprises two lakes formed around forty years ago through gravel extraction. The lakes are filled by the natural groundwater, which means they are very clean. In fact, you can usually see the bottom of the lake from the viewing gallery on the Millennium Building!
