Boulder Adventures, Llanberis offers outdoor activities and accommodation in Snowdonia, North Wales.
Probably built by Llywelyn ab Iorwerth ('the Great') early in the thirteenth century, the castle is dominated by a massive round-towered keep, still standing up to 50 feet (15.2m) high.
Please note that Electric Mountain is temporarily closed for refurbishment and upgrading. We hope to be back in the new and improved Visitor Centre by 2020.
This lovely little line runs alongside Llyn Padarn in the Padarn Country Park for a there-and-back journey of five miles. Stop off for a lakeside picnic at Cei Llydan, or visit the National Slate Museum at Gilfach Ddu.
