This walk explores the fascinating old Dinorwic Slate Quarry in Llanberis. At one time the quarry was the second largest slate quarry in the world, after the nearby Penrhyn quarry at Bethesda.
The site is now home to the National Slate Museum, covering more than 700 acres (283 ha) consisting of two main quarry sections with 20 galleries in each. The site is a fine place to explore on foot with towering walls of slate backed the mountains of Snowdonia.
The walk starts from Dinowic parking area at the western end of the site, just above Llyn Padarn. From here you can pick up the village tramway trail and follow it south east across the quarries towards Nant Peris. Around here you can pick up trails along Llyn Peris before heading back to the car park.

Further Information and Other Local Ideas
The site is part of the wider Padarn Country Park where you can also enjoy the Llanberis Lake Walk and the Llanberis Waterfall Walk.
The quarry is one of the significant sites on the Snowdonia Slate Trail which runs through the area. The circular long distance trail can be used to visit several of the other historic mining areas located in the World Heritage Site. Heading north along the trail would take you to Bethesda where you could visit the Penrhyn Quarry which was the largest slate quarry in the world during the 19th century. Heading south along the trail would take you to Dorothea Quarry where you'll find the remains of the old mining houses and a series of scenic lakes including Llyn Nantlle Uchaf.
The Llyn Peris Walk takes you up the steep zig zag path at the northern end of the lake. There are some fabulous views down to the lake from this elevated position.
