Snowdonia is a land of big hills. 


Snowdonia is a big park in North Wales. 


Snowdonia is a large national park in North Wales. 


Long ago, great ice sheets covered this land. This was during the ice ages. The moving ice carved the rocks into new shapes. It also left behind many lakes. Some lakes are natural. Others were made by people to hold water for power. The park also has a long coast by the sea. You can find sandy dunes and high cliffs there. More than 26,000 people live in the park. Many of them speak the Welsh language. It is a very popular place for visitors to explore.
Snowdonia, also known by its Welsh name Eryri, is a huge mountainous region. 
The landscape was shaped by many ice ages. Great sheets of ice moved across the land. This process carved the rocks into unique shapes. The last ice age ended about 11,500 years ago. Because of the ice, there are many lakes here. Some lakes sit in deep valleys called glacial troughs. Others are small lakes called tarns that sit in rocky hollows. 
People have lived and named this land for a very long time. 

The mountains are the most famous part of the park. 

Today, Snowdonia is a place where nature and people meet. 
Eryri National Park, commonly known as Snowdonia, is a vast mountainous region in North Wales. 
The landscape was shaped by intense geological processes. During a succession of ice ages, massive glaciers moved across the region. These glaciers carved the bedrock into a distinctive, rocky landscape. The last ice age ended approximately 11,500 years ago. This period of glaciation left behind many features that visitors see today. Even Charles Darwin recognized this connection. In 1841, he visited Cwm Idwal and realized the landscape resulted from glaciation.
The mountains are the most prominent feature of the park. 

The bedrock of these mountains is extremely old. Much of it dates back to the Cambrian and Ordovician periods. These rocks were affected by the Caledonian Orogeny, which involved intense folding and faulting. Low-grade metamorphism of ancient mudstones created the local slate. 
Water is another essential part of the Eryri landscape. The park is home to most of the large natural bodies of water in Wales. Llyn Tegid, also known as Bala Lake, is the largest natural lake in the country. Many other lakes occupy glacial troughs or small rocky hollows called tarns. 
The history of the park's name reflects its cultural roots. The name "Snowdon" comes from Old English words meaning "snow hill." The Welsh name for the mountain is Yr Wyddfa. The name "Eryri" likely means "place of the eagle." 
Today, more than 26,000 people live within the park boundaries.
