Tourists are being urged to stay away from Brombil Reservoir in Margam, South Wales, after its owners introduced a £2 levy per visit to deter growing numbers. The reservoir, known as the 'blue lagoon', dates back to the 19th century and is around 100 feet deep, rumoured to contain several abandoned cars. It is located near Port Talbot steel works and requires a steep 900-metre public footpath to access.
Viral fame brings problems
The reservoir gained viral attention during the pandemic as people sought peaceful escapes, with some TikTok users calling it one of the most beautiful sights in Wales. However, its popularity led to complaints from locals about traffic, fly-tipping, and littering. Visitors have documented enormous amounts of rubbish, including drinks cans, water bottles, and plastic bags, left along the path and around the water.
Owner response
Since 2024, the reservoir has been owned by Leisure Estate Investments Ltd. The company introduced the levy as a 'temporary deterrent' and installed barriers on its dam face, though reports from the BBC indicate these have already been dismantled by trespassers. A spokesperson for the company told the BBC: 'Our long-term vision has always been to build a sustainable public-private framework so the community can safely enjoy this asset. However, managing a critical piece of infrastructure presents immense structural, environmental, and financial challenges that cannot be indefinitely sustained by a private entity alone.'
The owners also face costs from Natural Resources Wales, a Welsh Government Sponsored Body, which charges an annual fee of £276 for regulated reservoirs. Leisure Estate Investments Ltd said repeated attempts to seek support from Neath Port Talbot council and local politicians have been unsuccessful.
Risk to reservoir
The reservoir has a 'unique aquatic system' and plays a crucial role in flood protection, helping shield downstream residential areas. Without public sector support, it could be at serious risk. On social media, the owners are imploring people who 'love and cherish this special place' to help keep it safe by giving donations.
