Move over, Iceland. Tucked away in the rugged heart of Snowdonia, the tiny, almost-forgotten village of Cwmorthin has become the backdrop for a stunning natural phenomenon that's taking the internet by storm.
A former slate quarry, which spent decades filled with murky water, has undergone a miraculous transformation. The water has now cleared to reveal a mesmerising, vibrant turquoise hue, so vivid it rivals the famous geothermal spas of the Mediterranean.
From Industrial Past to Turquoise Paradise
The dramatic change is due to a natural process. As the quarry settled over time, fine particles of slate dust that once clouded the water finally sank, allowing the sun to illuminate its stunning aquamarine colour. The result is a breathtaking lagoon that looks more at home in the Caribbean than North Wales.
"It's absolutely incredible to see," said a local walker who wished to remain anonymous. "One year it was dark and gloomy, the next it's this unbelievable shade of blue. It's put our little corner of the world on the map."
A Word of Caution for Eager Explorers
Despite its idyllic appearance, locals and authorities are urging visitors to exercise extreme caution. The water is deceptively cold, and hidden machinery lies beneath the surface, creating potential hazards for swimmers.
While wild swimming is not officially recommended, the area offers spectacular viewpoints for hikers and photographers eager to capture the lagoon's beauty from a safe distance. The surrounding landscape of abandoned quarry buildings and dramatic mountain slopes adds to the unique, almost mystical atmosphere.
How to Find Wales' Hidden Gem
Reaching Cwmorthin requires a sense of adventure. The village itself is largely uninhabited, accessible via a narrow road from the nearby town of Blaenau Ffestiniog. The lagoon is best approached on foot, with several public footpaths leading to viewpoints that overlook the spectacular site.
This unexpected discovery proves that you don't need to travel thousands of miles to find wonder. Sometimes, the most magical places are hiding in plain sight, waiting for a natural change to reveal their true colours.
