The mountains of the Snowdonia National Park in North Wales are one of the most popular places to visit in Wales. Few of Snowdonia’s peaks top 900 meters (3,000 feet), but their steeply wooded slopes lend them a heightened sense of drama. They also provide a stunning backdrop to the park’s estuaries, lakes, rivers, slate mines and villages. Hiking is a popular activity in Snowdonia, and there are Neolithic burial cairns and Roman ruins to explore in the park too. A cog railway takes visitors to the top of Snowdon, the park’s namesake and highest peak.
