Porth Glastwr, also known as the Blue Lagoon, is a stunning coastal bay located in Pembrokeshire, Wales. Situated near the small village of Abereiddy, this natural wonder has gained popularity due to its breathtaking beauty and unique features.

The bay is characterized by its dramatic cliffs, which surround a deep, clear-blue water-filled quarry. The vivid hue of the lagoon is a result of the quarry's former use as a slate quarry, with minerals from the surrounding rocks seeping into the water. The contrast between the blue water and the rugged cliffs creates a mesmerizing sight that attracts both locals and tourists alike.

Porth Glastwr offers a range of activities for outdoor enthusiasts. The lagoon itself is a popular spot for diving, with its crystal-clear waters providing excellent visibility for exploring the underwater world. The cliffs surrounding the bay are a haven for climbers, offering various routes of different difficulty levels. Additionally, the bay is a great spot for kayaking and wild swimming.

The area surrounding Porth Glastwr is also home to diverse wildlife, making it an ideal location for nature lovers. Seabirds, such as razorbills and guillemots, nest on the cliffs, and seals can often be spotted lounging on the rocks or swimming in the bay.

Overall, Porth Glastwr, or the Blue Lagoon, is a remarkable natural attraction in Pembrokeshire. Its stunning beauty, outdoor activities, and diverse wildlife make it a must-visit destination for those seeking adventure and natural wonders.
