Mynydd Hendre-ddu (pronounced 'Min-ith Hen-dre-thee') is a mountain located in the southern part of Snowdonia, Wales. It is also sometimes called Mynydd Hendreddu. This mountain is part of a long line of peaks that stretch across the landscape.

Mynydd Hendre-ddu acts like a natural dividing line for water. It separates streams that flow southwest into the Afon Dulas river from those that flow north and east into the Afon Angell and then into the larger River Dyfi. This is called a watershed.

What Makes Mynydd Hendre-ddu Special?

The very top of Mynydd Hendre-ddu, called its summit, has something interesting to see. There are several parallel ridges, which are like long, narrow bumps on the ground. These ridges are about 80 centimeters (about 31 inches) wide and stretch for about 130 meters (about 426 feet).

A Look at the Past: Hendreddu Quarry

On the northern side of the mountain, there used to be a place called the Hendreddu quarry. A quarry is where people dig out rocks or minerals from the ground. This quarry was known for its slate, a type of rock often used for roofing.

To move the slate from the quarry, a special railway called the Hendre-Ddu Tramway was built. This tramway connected the quarry to the nearby village of Aberangell. It was an important way to transport the slate to other places.

Part of the Dyfi Hills

Mynydd Hendre-ddu is also considered one of the Dyfi hills. The Dyfi Hills are a group of mountains and hills located around the River Dyfi valley in Wales. This area is known for its beautiful scenery and natural environment.
