The popular Blue Lagoon at Abereiddy will close this autumn to protect a booming seal population.
The Pembrokeshire coast is a popular place for breeding Atlantic grey seals which have arrived early this year to have their pups on the secluded beaches. The lagoon is often filled with seals and their pups this time of year and it is closed off by National Trust Cymru every year in late September to stop them being disturbed.
But thanks to their early arrival at the end of the 2022 summer, the Trust has decided to close the former slate quarry earlier than expected on September 17. The annual closure usually runs until November. Increasing numbers of grey seals breeding in and around the lagoon coupled with the Blue Lagoon’s high visitor numbers and its sheltered nature means there is a high potential for disturbance to seals, the Trust said.
