Moel Eilio may not be the most exciting mountain in Snowdonia, but when the conditions are right it can be a truly spectacular viewpoint to Snowdon, the Glyders, and the Beddgelert hills.

At the start of the 20th century, this was the second largest slate quarry in Wales (and thus, the world), covering over 700 acres, consisting of two main quarry sections with 20 galleries in each.

For a route that combines easy walking with local history, consider the Dinorwic Slate Quarry โ€“ Dinorwig Slate Mine Ruins loop from Llanberis, which is relatively short and explores the fascinating quarry remains.

What are the parking options for hikes starting near Llyn Peris?

Most hikes start from or near the village of Llanberis, which has several pay-and-display car parks. These can get very busy, especially on weekends and during holiday periods, so arriving early is strongly recommended.

Are dogs allowed on the hiking trails?

Dogs are welcome on most public footpaths in the area, including those in Padarn Country Park. However, you will be walking through a landscape with active farmland, so always keep your dog on a lead, especially near livestock. Be aware that some stiles may be difficult for larger dogs to cross.
