Stay away from our blue lagoon, owners warn after beauty spot goes viral on TikTok

The owners of the “blue lagoon” in South Wales that went viral on TikTok have warned people not to enter the site.
Brombil Reservoir, near Neath Port Talbot, has attracted a number of visitors since it first took social media by storm during the Covid-19 pandemic, which has reportedly caused traffic and litter problems in the area in the past.
Known for its turquoise blue waters, the beauty spot is located in a valley on Mount Margam and can be reached via a steep 900-metre public footpath. The body of water is locally called the “blue lagoon”.
The reservoir has been owned by Leisure Estate Investments Ltd since 2024 and it said its aim was to open the site for public use in a safe manner.
But now the owners are introducing a £2 per visit tax and installing barriers on the face of the dam as a “temporary deterrent”.
The trespassers removed the barriers, according to the BBC.

It was shared on social media that all activities, including swimming, hiking, motorcycling, filming and camping, are prohibited without the prior permission of the management team.
The management team shared a statement earlier this summer: “Our long-term goal is to open this area safely for the health and well-being of the community. However, the reservoir is currently a high-risk infrastructure area and remains private property.
“For your own safety, we strongly discourage public access at this time and all entry is entirely at your own risk,” they said.
“Managing this site requires significant private funding for environmental protection and flood maintenance. If you choose to visit please support our conservation efforts by paying our £2 site maintenance fee.”
This “maintenance fee” will be used to clear garbage, cut down vegetation, clear the storm drain, protect local biodiversity and repair structural damage, they said.
Managers warned: “Unauthorized activities are strictly prohibited on these premises. We reserve the right to take legal action against any person or entity acting without prior written consent.”
The website describes the area as “perfect for nature lovers, adventurers, filmmakers and ecology enthusiasts.”
It was auctioned for £20,000 in September 2024 after first being released with a guide price of £75,000. Wales Online.
The Independent has contacted Brombil Reservoir management and Neath Port Talbot Council for comment.
