The village of Deiniolen, housing a village pub and shop, is 4 miles north of Llanberis, on the border of the Snowdonia National Park, making it an ideal base to explore the National Park. The Llanberis Railway runs nearby along the banks of Lake Padarn, whilst the ruins of Dolbadarn Castle are 2 miles away, or visit Ceunant Mawr, a cascading waterfall just outside Llanberis. Local walks lead to the Marchlyn Mawr Reservoir on the northern slopes of Elidir Fawr. Llanberis is 4 miles away and is flanked by two lakes, Llyn Padarn and Llyn Peris and is one of the most popular mountain tourist centres in the Snowdonia National Park. In fact, Llanberis is something of a “mecca” for walkers and climbers, being the starting point for the ascent of Snowdon – the highest mountain in England and Wales. The ascent can be made either by train, on the Snowdon Mountain Railway, or on foot along one of the many routes to the summit. Each year, major racing events attract thousands to the area: The fast Snowdon Race to the summit, held in July every year and The Snowdonia Marathon, held in October – a gruelling 26 mile course that starts and finishes in Llanberis, circumnavigating the Snowdon Massif. Within Llanberis itself there are excellent places to eat and drink and a great choice of shopping. On the coast is Caernarfon with its magnificent castle and town walls and close by are National Trust properties at Penrhyn and Plas Newydd.
