Gwynedd. The Holy Well of St. Bueno, in Clynnog Fawr, was once the source of water for the monastic community there. St. Beuno reputedly had miraculous powers, and the spring became a famous healing well, and it reputedly cured many ailments from epilepsy to nervousness. It was a favoured well for curing eye problems, and children would be brought to the well from many miles away to be healed of their illnesses. The well is walled, with an open top. There are steps that lead down to the water, where there are seats. After the sick had bathed there, they may have been taken to St. Bueno’s chapel where they could have spent the night laying on top of the saint’s tomb. Clynnog Fawr is on the pilgrim’s route through the Lleyn peninsula to Bardsey Island.

Pwllheli is a small town with several cafés, pubs and restaurants, as well as a big supermarket (Asda), long sandy beach, promenade and marina. In terms of tourism, Pwllheli is mostly overshadowed by nearby towns like Abersoch, Criccieth, and Porthmadog. However it offers plenty for people passing through or wanting a place for the night, and I feel the beach is very worthy of a detour!

Nefyn is a beautiful little north coast seaside village with harbour, museum and a graceful sandy crescent beach. The Llyn Maritime Museum tells the story of the peninsula’s often stormy relationship with the sea.

The settlement of Clynnog-Fawr was once a busy stopping place for medieval pilgrims on their journey to Bardsey Island. Over time, the original church here became a pilgrim destination in its own right. The church you see today is younger, dating back to the 15th and 16th centuries. It's imposing and impressive in quite a small village. There's a 10th-century sundial in the churchyard.
