**Demonstrators Rally at Cosmeston Lake over Proposed Water Park Development**
A spirited protest unfolded at Cosmeston Country Park today as local residents—young and old alike—voiced their dissent against proposals to introduce an inflatable water park at the much-loved lakeside nature reserve. The demonstration comes in response to the Vale of Glamorgan Council’s recent decision to allow Cardiff Bay Aqua Park to temporarily relocate to Cosmeston’s eastern lake for an eight-week trial this summer.
The news of the council’s plans, announced in May with a July launch date, has stirred deep concern among environmentalists and community members who cherish the park’s tranquil environment and diverse habitats. Dozens gathered at the main entrance to Cosmeston Country Park, clutching homemade placards and calling for the protection of a site they feel is under threat.
Set across 100 acres, Cosmeston is not only a popular green space but also home to a Site of Special Scientific Interest (SSSI). This status underlines the ecological significance of the area and its rare mix of plant and animal species. The SSSI designation typically ensures high levels of protection from disruptive development, and many protesters argue that a summer water park is incompatible with such values.
Angela Peterken, a forest school leader who teaches children about the local wildlife around the lake, was among the passionate voices at the protest. Holding a sign that read “Forest School says keep Cosmeston for wildlife!”, she stressed the importance of preserving the area’s calm and natural state. “People value the peacefulness here—it’s just not the right setting for a water park,” she argued. “Even though this is being called a temporary measure, you can’t expect wildlife to simply return once the inflatable course has been packed away. Habitats can take years to recover from disruption.”
Her concerns were echoed by a nine-year-old regular of the forest school, who dismissed the water park proposal as “ridiculous.” She stated, “This lake is a home for wildlife. If the water park comes, it won’t be quiet anymore, and the animals won’t come back.”
Further reflecting local opinion, a petition against the water park, signed by over 5,000 people, has circulated amidst fears about deteriorating water quality, increased disturbance, and irreversible environmental damage. Campaigners also worry that light and noise pollution could negatively affect local birds, mammals, and aquatic species. Some parents at the protest spoke of their children’s distress upon hearing the news, highlighting the deep attachment many local families have to the natural space.
In response, Vale of Glamorgan Council defended its decision, pointing to collaborative work with partner agencies and a comprehensive water quality monitoring regime. The council also cited an ecological assessment which, they say, found no significant risk to local birdlife or water vole populations. Councillor Bronwen Brooks, deputy leader and cabinet member for sustainable places, said, “The Aqua Park will be a new addition to our leisure offerings in the area, especially as consultation has shown demand for more activities among young people. We’re determined to ensure our country parks are accessible to everyone.”
Nonetheless, not all remain convinced. Philippa Newman and Saar Lenaerts-Williams, who helped organise the demonstration, have called into question the adequacy of the environmental report and urged the council to prioritise existing habitats. “There are so few wild spaces left,” Philippa explained, “and this is simply the wrong location for such a venture.”
Also weighing in, Connor James, founder of Aqua Park Cardiff, expressed his excitement about the trial: “We’re thrilled to be partnering with the council to bring our watersport experience to Cosmeston. The park is ideal for family adventure and outdoor fun, all under safe supervision.”
As the summer approaches, the debate shows no signs of cooling. While the council and the Aqua Park’s backers look ahead to a busy season, residents, wildlife advocates, and forest school pupils remain adamant that Cosmeston’s rare habitats should not be put at risk—even temporarily. The coming weeks will likely determine whether recreation and conservation can find common ground at one of the Vale’s greenest treasures.
